Leading by examples – retrofitting all types of social housing – part two

Posted on by

By Ian Babelon

In the first part of two blog posts, published on 22 May, Ian Babelon provided examples of good practice in retrofitting social housing. The second part of this blog post looks at estate-wide and area-wide social housing retrofits.

Introduction

Upscaling social housing retrofits requires learning from individual property retrofits and wider retrofitting programmes. With numbers comes greater complexity. As capacity grows, opportunities for partnerships provide new opportunities to embed retrofit programmes in wider sectoral and place-based strategies. This post considers the role of estate-wide and area-wide social housing retrofits, including how these can benefit from tenant engagement for healthy, inclusive placemaking.

Estate-wide retrofits

Low-carbon retrofitting measures on Lancaster West Estate at the Royal Borough of Kensington and Chelsea have included Energiesprong whole house retrofits at 38 homes, energy-efficiency measures at 367 homes across seven blocks, and testing mechanical ventilation heat recovery systems. The latest measure is the fully carbon-neutral retrofit at Treadgold House. Other measures have included public realm and safety improvements. Along with the extensive resident engagement, the estate has witnessed a deep one-of-a-kind transformation.

However, estate-wide retrofits can be difficult to plan and deliver to a high energy-efficiency standard due to the large up-front costs involved. A mix of whole-house retrofits, fabric-first approaches, redevelopment of poorly designed buildings, and essential scheduled upgrades might be preferable, depending on the context and the heavy cost of building safety compliance.

The acclaimed Passivhaus redevelopment of Agar Grove in Camden, based on the masterplan by Hawkins\Brown, features a mix of solutions that make the estate-wide regeneration more affordable for both the council and residents. These include new council homes, refurbished flats, affordable rental housing, and homes for sale, enabling a tall order of 496 new homes to be delivered in six phases. Besides providing much-needed quality homes to many, the project also acts an exemplar for social and affordable housing in the UK and beyond.

Area-wide programmes

From being an early adopter of the Energiesprong approach to the Deep Retrofit Energy Model (DREeM), enabling  energy-efficient retrofits to dozens of social homes, Nottingham City Homes have been among the first in the UK to develop neighbourhood-wide retrofits. Nottingham City Council even tested the innovative use of Low Temperature District Heating along with whole house retrofits for 94 homes in Sneinton, which proved more complex than initially expected.

In Scotland, the Renfrewshire retrofit programme aims for EnerPHit or AECB Retrofit Standard for up to 3,500 homes across eight neighbourhoods. The initiative is part of a £100m housing-led regeneration programme across the local authority. Renfrewshire Council was selected as Social Landlord of the Year 2022 by the Retrofit Academy for its clear strategy to deliver large-scale housing decarbonisation, adopt the PAS2035 framework wherever possible, and for its proactive engagement of residents throughout the programme.

Other noteworthy programmes include whole house retrofits for 150 council-owned flats on the Holt Dale Estate in Leeds, reaching EPC rating A, benefitting residents who were living in fuel poverty. The 3 Cities Retrofit programme is worth following up as it has the potential to retrofit up to 165,000 social homes across the Birmingham, Coventry and Wolverhampton City Councils.

In France, 14 housing associations in Brittany have partnered to leverage the Energiesprong approach for an initial stock of 2,000 social homes, with a potential to extend the experience to 16,000 social homes. In the north of France, the housing association Maison et Cités selected hemp concrete as the most effective material for a progressive roll-out of fabric-first retrofits to 20,000 homes in the former mining region. Both area-wide retrofit approaches were part-funded by the French public investment agency Banque des Territoires.

Upscaling tenant engagement

Residents should be onboard from day one of their property’s retrofit, but they can also actively contribute to wider retrofit programmes. Insight from the Social Housing Tenants’ Climate Jury report (2021) and the Resident Voices in the Net Zero Carbon Journey report both point to the need to educate and actively involve residents from the planning phase to supporting sustainable lifestyles.

One year on, these needs were felt even more acutely in the build-up to COP26. Critically, residents have expressed that perceived contradictions in council-led environmental strategies such as recycling can have knock-on effects on how they perceive the value and effectiveness of retrofits. This implies that efforts toward improving energy-efficiency and reducing waste should be consistent.

Resident-led and national initiatives have included community gardening and the Incredible Edible network. These can provide additional involvement opportunities as well as quality food and care for the neighbourhood. The demand for greener urban spaces, biodiversity and access to wildlife also came strongly in a related report by Orbit and the Chartered Institute of Housing. Initiatives that upscale tenant engagement include recruiting tenants as board members (at Connect Housing) or embedding tenant involvement in the housing provider’s sustainability strategy (at Notting Hill Genesis).

Providers can also encourage residents to contribute to the Together with Tenants Charter led by the National Housing Federation. The organisation Tpas and partners have shared tenant engagement guidance for ALMOs and housing associations that will be useful in seeking to upscale social housing retrofits. In addition, there has been a recent ministerial push encouraging tenants to voice their concerns more readily, and therefore to exercise scrutiny over what may be dismal housing conditions.

Final thoughts

Collaboration and cross-sectoral partnerships underpinned by active tenant engagement seem essential to deliver large retrofit programmes while hedging against otherwise deterring risks. Exemplars, in turn, help build a greater ‘can do’ attitude and know-how for the wider housing and property sectors on the road to net zero, including area-wide retrofits.

What goes around comes around: how the circular economy can reduce waste and address climate change

Posted on by

This week, the crucial COP26 summit gets under way in Glasgow. The meeting will bring together government leaders, climate experts and campaigners with the aim of agreeing coordinated action to tackle global climate change.

The discussions will be wide-ranging, covering major themes such as deforestation, renewable power generation, and electrification of transport. But although it might not hit the headlines, there’s another issue that could play a critical role in meeting climate change goals: the circular economy.

Producing, consuming and disposing of the products we use in our everyday lives accounts for nearly half of all greenhouse gas emissions. Cutting those emissions means upending the conventional “take-make-consume-dispose” model of growth, and designing waste out of our economy altogether.

In advance of the COP26 meeting, The Economist magazine hosted a webinar which focused on the potential of the circular economy for emissions reduction.

The challenges of going circular

Introducing the event, Vijay Vaitheeswaran, The Economist’s global energy and climate innovation editor, explained that the essence of the circular economy is about keeping materials in circulation and maintaining their utility. But how much of a Utopian dream is this, and what are the practical challenges that need to be overcome if this elegant theory is to become a reality?

In response, Federico Merlo, managing director of member relations and circular economy for the World Business Council for Sustainable Development, explained that, while changing business models to extend the life cycle of products would not be easy, the economic benefits of using and wasting fewer materials should drive business in the direction of the circular economy.

Jim McLelland, Sustainable Futurist at SustMeme, was concerned about possible resistance from consumers in changing their behaviour. Because many people equate consumption with ‘shopping’, they don’t consider the emissions generated during the journey of materials from design to finished product. This could result in friction in the transition to the circular economy.

But Kai Karolin Hüppe, sustainability & circular economy lead for Arthur D. Little management consultants, suggested consumers were becoming more curious about how the materials that made their products came to be in them. And once they know the impact of consumption, people can make informed buying decisions. 

She went on to explain how this is getting easier, thanks to new tools from the Greenhouse Gas Protocol and the Science Based Targets  initiatives, which can help to identify, measure and manage emissions throughout material life cycles. When the Kraft food company mapped out the sources of its own emissions, it discovered that over 90% were not directly generated by the business, but by indirect sources, such as suppliers and distributors.

Making plastic circular

In recent years, there has been much greater awareness about the environmental damage caused by plastic. One of the world’s biggest plastics manufacturers is Dow, and the company’s commercial vice president for packaging and specialist plastics took part in the webinar to outline how it’s addressing the issue.

Marco ten Bruggencate explained that, while Dow is taking sustainability seriously, the company needs to go much faster. Doing this means making sure the whole production process is addressed, from the way factories are powered to the use of renewable feedstocks to make bio based plastics. And now, Dow is looking at how to make plastics part of the circular economy by making sure that valuable waste is looped back into new packaging structures.

Raising awareness

Education has a vital role to play in the circular economy, and Jim McLelland highlighted an initiative that is providing the construction industry with greater understanding of sustainability issues.  The Supply Chain Sustainability School is funded by major construction contractors, and provides free access to training for suppliers and subcontractors in a range of disciplines, including common standards for sustainability. Jim noted that construction is responsible for 38% of global emissions, and a typical supply chain involves large numbers of materials and many microbusinesses in different countries and regions. The collective approach offered by The Supply Chain Sustainability School is an important contribution to a sustainable built environment.

Reversing the trend

Jim is one of the authors of the Circularity Gap Report, an annual progress report on the journey to a global circular economy. The first report, published in 2018, established that the world was only 9.1% circular. But the most recent report put the figure at 8.6% circularity.

It appears that the world is going in the wrong direction, but there are now signs that businesses are moving forward with their own ideas.

The packaging sector, for example, is exploring digital technologies that could drive a truly circular economy – such as blockchain to help with tracking material flows, and digital watermarking to enable better sorting of packaging waste.

And achieving circularity doesn’t mean a company has to completely rethink its business model. Global sportswear giant Nike was able to reduce the waste generated by one of its running shoes by 80% simply by talking to their supply chain.

Final thoughts

COP26 has been described as world’s last best chance to get runaway climate change under control. For all of us, the stakes could hardly be higher. Failure to limit global temperature increases to well below 2 degrees Celsius risks greater pressures on water and food supplies, increased hunger and poverty and more frequent flooding, storms and heatwaves that threaten plant, animal, and human life.

Yet if we were able to double the current 8.6% global circularity figure to achieve 17% circularity, that move alone would achieve the targets on global warming set out by the Paris COP meeting in 2015.

Whatever the outcome of the talks in Glasgow, it should now be clear that the circular economy is a vital element in fostering low-carbon growth. And it might even tip the balance in the battle against global warming.

Role models for a new economic landscape: lessons from Europe’s Green Capitals

Posted on by
Hamburg: StadtRÄDER bike rental system

Last month, the French city of Grenoble was crowned European Green Capital for 2022. Since 2010, this award has been presented by the European Commission to cities judged to be at the forefront of sustainable urban living.

Being named Europe’s Green Capital is good PR for any winning city, and the €350,000 prize is an additional incentive to win. But the award also places demands on the winners to build on the environmental improvements that helped put them in first place.

The key message of the award is that Europeans have a right to live in healthy urban areas. Cities should therefore strive to improve the quality of life of their citizens and reduce their impact on the global environment.

Cities bidding for the award are judged on a range of environmental criteria, including climate change, local transport, public green areas, air quality, noise, waste, water consumption, wastewater, sustainable land use, biodiversity and environmental management.

The award enables cities to inspire each other and to share examples of good practice. So far, 13 cities have been named European Green Capitals:

2010: Stockholm (Sweden)

2011: Hamburg (Germany)

2012: Vitoria-Gasteiz (Spain)

2013: Nantes (France)

2014: Copenhagen (Denmark)

2015: Bristol (United Kingdom)

2016: Ljubljana (Slovenia)

2017: Essen (Germany)

2018: Nijmegen (Netherlands)

2019: Oslo (Norway)

2020: Lisbon (Portugal)

2021: Lahti (Finland)

2022: Grenoble (France)

Green approaches

Each city has adopted different approaches during its year as a green capital.

  • One very clear example of Stockholm’s commitment to sustainable development during its year as European Green Capital was the opening of a new tramway. The line opened in August 2010 and quickly achieved substantial environmental and economic impacts.

  • One of the campaigns during Hamburg’s year as green capital in 2011 aimed to make it easier for citizens to switch from cars to bikes and public transport. The Hamburg Transport Association distributed 2,735 free tickets to friends and acquaintances of season ticket holders, and many visitors made use of the free advisory and ‘get involved’ activities of Germany’s national bicycle club. During the year, Hamburg’s StadtRÄDER bike rental system was also promoted, resulting in an 8% increase in the number of users.

  • Even before it was named as a European Green Capital, Grenoble, had already made efforts to address noise pollution, promote cycling and reduce speed limits. It has also taken a proactive approach to maximising its limited green space by encouraging citizen-led planting initiatives. Grenoble reduced greenhouse gas emissions by 25% from 2005 to 2016 and is working towards a 50% reduction by 2030.

Britain’s green capital

The only UK city to be awarded the European Green Capital prize is Bristol, which held the title in 2015. The city hosted a number of art projects to raise awareness about sustainable development. Bristol also began a trial of ‘bio-buses’ powered by biomethane gas, using human waste from more than 30,000 households, an initiative that was developed further in 2020.

The selection of Bristol opened up a serious debate about  the true value of the award, with some regarding it as a distraction from Bristol’s serious environmental issues, such as traffic congestion, while others were critical of public funding for some European Green Capital projects as wasteful.

However, an important legacy from the year was the publication of the “Bristol Method”, a knowledge-transfer programme aimed at helping people in other cities understand and apply the lessons that Bristol learned in becoming a more sustainable city.

The Bristol Method is made up of a series of modules, each of which uses Bristol’s experience to present a ‘how to’ guide on a particular topic. Topics include:

  • how to use partnerships to drive change;
  • how to use grants to support grassroots change;
  • how to prepare a winning bid for the European Green Capital;
  • how to grow the green economy in a city;
  • how to get more people riding bikes and walking;
  • how to protect and enhance green spaces in a city.

Green shoots for a post-Covid recovery

Although the world is currently preoccupied by the coronavirus pandemic, that other serious planetary threat –  climate change – has not gone away. So it’s significant that many governments see this moment as an opportunity to build radical green policies into their packages for economic recovery.

Some of the practical ideas developed over the past decade by Europe’s Green Capitals are important in their own right, but may also be seen as key elements in rebuilding economies that have been devastated by restrictions to suppress the coronavirus.

The German city of Essen, for example, (European Green Capital in 2017) has developed one of Europe’s largest infrastructure projects, restoring 80 kilometres of waterways and creating a network of green spaces. The project was not only an important climate adaptation milestone, but has also created new jobs and business opportunities. Essen has shown that it’s possible for a city which previously relied on heavy industry to transform itself into a vibrant and sustainable space for humans, animals and plants.

Another project, in the Dutch city of Nijmegen, (Green Capital in 2018) is a social enterprise that collects, restores and re-sells second-hand goods. The venture prevents waste, as well as employing people who can put their repair and retail experience to good use. Similar projects across the Netherlands have collected 20,000 tonnes of goods a year, with 80% being re-used. They also provide jobs for disadvantaged and disabled people who have found it especially difficult to enter the labour market.

Europe’s Green Capitals have already become role models for green economies throughout Europe and beyond. Now they can demonstrate the economic as well as the environmental benefits of building back greener.

Guest post: Why we’ll still need waste in a circular economy

Posted on by

Stijn van Ewijk, Yale University and Julia Stegemann, UCL

Every year, we buy 30 billion tonnes of stuff, from pizza boxes to family homes. We throw out or demolish 13 billion tonnes of it as waste – about 2 tonnes per person. A third of what we discard was bought the same year. The extraction, use and discarding of so much stuff creates a large environmental burden, from the depletion of minerals to the destruction of rainforests.

The idea of a circular economy aims to address these problems by rejecting the take-make-dispose model of production and consumption that governs our world. Instead, waste is “designed out” and materials are kept at a high value for longer through reuse, repair and recycling.

Find another use for it.

Unfortunately, some wastes are an inevitable result of growing or making things, and even durable products such as cars, toasters and smartphones eventually break down or become useless. So how should we deal with it? In a recent paper, we argue for a legal requirement to recognise the potential for this waste to be used again.

Why waste is necessary

To deal with waste, we must first understand why it is there. Waste consists of products that are unwanted and so little attention is currently paid to their fate. As a result, they tend to end up in the wrong places, including ecosystems that supply our food and drinking water. After all, the cheapest way to get rid of waste – a plastic bag, old furniture – is to dump it.

The first waste management systems were introduced to address the public health problems that emerged from this habit. The 1854 cholera outbreak in London was caused by the unsafe disposal of human waste in urban cesspools. The accumulation of plastic waste in the ocean today – which ensnares and chokes wildlife while contaminating the seafood we eat – has the same root cause: ineffective waste collection and treatment.

To avoid litter and dumping, governments define everything we discard as waste. Once that happens, strict regulations apply for its transport, treatment and disposal. For example, when you have your car tyres replaced, the car workshop needs a permit, or a permitted contractor, to legally and safely reuse, recycle or dispose of the old tyres.

Used tyres are regulated as waste to prevent their unsafe reuse and illegal dumping.
Ich bin dann mal raus hier/Pixabay, CC BY

But defining a potentially valuable material as waste can complicate the process of using it again for another purpose. A construction firm may want to reuse the tyres from the workshop, but since they’re classified as waste, both parties have to fill out paperwork just to show they’re meeting the waste handling requirements.

Defining fewer materials as waste cuts out paperwork and makes reuse easier. But tyres are flammable and release chemicals as they wear down. If the reuse of tyres was unregulated, it could compromise fire safety and endanger our health. Without strict regulations, the car workshop might even resort to illegal dumping, which is already a major problem.

The use potential of waste

This leaves regulators with a dilemma. How can we strictly regulate waste while promoting its reuse? The solution is to think ahead. If we know in advance how and to what extent waste can be used again – its “use potential” – we can regulate it more effectively. Most importantly, we need to design products to be safely reusable and create regulations that allow and encourage reuse.

For example, if we design car tyres that aren’t flammable or toxic, they can be reused in a wider range of applications. To get manufacturers to develop and use these products, governments need to help them identify the use potential of the resulting waste. Tyres could be approved and labelled not only for their first use on a car, but also for their subsequent reuse in construction.

A universal requirement for designers to increase the use potential of waste, and for product users to fulfil this potential, can ensure waste is repeatedly used, without having to change the definition of waste and how it’s regulated. Waste is still a necessary concept for keeping us safe and preventing illegal dumping, but we should think about it even before it’s generated, rather than pretending it can be made to vanish entirely.

Recycling: is it worth it?

Posted on by

By Helen Bird, Resource Management Specialist, WRAP

‘Single-use’ was coined 2018’s word of the year – and it’s not hard to see why after we collectively became aware of the devastating impact single-use plastic can have watching the BBC’s Blue Planet II and Drowning in Plastic.

Everybody seems to be discussing the plastic crisis – what the problem is, whose fault it is, what the right thing to do is… the list goes on. There has also been a lot in the media which can cause confusion and apprehension about what you should be doing at home to be as environmentally friendly as possible – fundamentally, for perhaps the first time it’s made us question whether recycling is really worth it after all.

And yet we’re recycling more than ever – twice as much as we did 15 years ago, in fact! So what’s the solution? What can we do about the scourge of plastics – is recycling really the answer?

The most important thing I should stress at this point is that recycling is always the most environmentally friendly way to dispose of your rubbish. By putting something in your general rubbish bin, it’s guaranteed to end up in landfill, or be used for energy from waste; but recycling gives that material the best chance of staying in use and out of the wider environment.

But at WRAP (Recycle Now’s parent organisation) we’re also working ‘behind the scenes’ with the industry and governments to make the recycling system better and simpler. Here’s how:-

What’s being done about the plastics crisis?

This year WRAP launched a world-first initiative, The UK Plastics Pact. The Pact works across the whole industry with Government, supermarkets, businesses, governments, industry and NGOs – from design to disposal – aiming to make plastic pollution a thing of the past. Its aims are to not just increase the recycling of plastics and improve the recycling system, but also to eliminate unnecessary single-use plastic packaging altogether, and increase the amount of recycled material in plastic packaging. A LOT is happening.

88% of us are reporting to have changed how we use plastics after watching Blue Planet II. The supermarkets are seeing the effects of this – Waitrose, for example, have recently reported sales of loose pears to have increased 30 times the rate of bagged, and they expect this trend to continue. But we also need to consider how we can make packaging more sustainable when it does need to be used – and in many cases, it does need to be used to prevent food waste, which is a huge contributor to greenhouse gases and carbon emissions.

One of the targets of The UK Plastics Pact is for all plastic packaging sold by Pact members to be reusable, recyclable or compostable by 2025. Brand and retailer members of the Pact (which between them account for more than 80% of all the packaging we buy daily) are making changes to their packaging, for example by removing or reducing the amount of plastic used, switching to more recyclable plastics and providing re-usable alternatives. Some examples can be found on the WRAP website.

What about compostable plastics – are they the answer?

We are considering opportunities for compostable plastic packaging – while compostable sounds like it will have a minimal on the environment, it has to be disposed in a particular way in order for them to be beneficial and can cause more issues if not dealt with correctly. Our work in this area will help ensure the most sustainable type of plastic is picked for the scenario in which it’s used.

What is Government doing?

The Government has already made some progressive steps to prevent plastic pollution and improve recycling – such as introducing the single use plastic carrier bag charge.

In the Autumn Statement the Chancellor announced a new tax on plastic packaging which doesn’t have a minimum of 30% recycled content (subject to consultation). This will make it more costly for businesses producing plastic to make it from new, non-recycled plastic which is less environmentally friendly.

The Government also published a landmark Resources and Waste Strategy in December. Part of this addresses Extended Producer Responsibility (EPR) – where businesses that produce a material in turn pay a percentage its recycling costs. This is based on the principle of ‘Polluter Pays’, ensuring that the system works transparently and as best it can, funded by those that produce.

The Strategy is also pushing for more consistency in what’s collected for recycling at kerbside across the country – making it simpler for everyone to understand what should and shouldn’t go in the recycling bin. This is something WRAP has been championing for a while, as it makes recycling easier for everybody and it will ensure more plastic packaging is recycled.

The Government is also outlining plans to make food waste recycling collections available across the country. Reducing the amount of food we waste is important, but when food does need to be thrown away, recycling is the best option.

What’s being done about our recycling going overseas?

Recycle Now recently blogged about the recycling import restrictions in China, and what we can all do at home to help the situation.

WRAP believes we should be recycling more of our plastic waste in the UK; but also to see a better system for our recycling if it does have to be sent abroad. Under The UK Plastics Pact, there is a target to significantly increase recycled content in plastic packaging. This will help drive the UK market for recycling and therefore reducing the amount of material that is exported.

In the Resources and Waste Strategy Government recognises that there are failings in the current system and have pledged to consult on changes, including better controls on materials that are exported for recycling.

The UK is also a member of the Basal Convention, an international treaty originally designed to prevent developed countries sending developing countries hazardous waste. Amendments are proposed that could see mixed plastic packaging waste added to this.

What are local authorities doing?

The number of local authorities that are collecting a wider range of plastics (bottles and pots, tubs and trays) has increased to 79% – that’s up from 18% 10 years ago. Recycling in the UK is on the right path – and I have had many positive individual conversations with the UK recyclers about the future of the UK recycling industry.

At WRAP we have (and continue to) develop and share best practice guidance with local authorities and industry to make recycling easier for everyone.

Remember the Recycling Locator is always there too if you’re not sure what to recycle in your area.

What can we do at home to help?

Remember that taking a tiny amount of time to recycle gives plastic the best chance to be transformed into a new item and out of our environment. Here are my top tips:

  • Leave lids on plastic bottles – squash the bottle first before replacing the lid
  • Recycle from the bathroom – remember shampoo and shower gel bottles can be recycled too!
  • Recycle plastic film at supermarkets – they often have collection points for plastic bags
  • Give items with food residue a quick rinse
  • If in doubt, check before you chuck – visit our Recycling Locator to find out what you can recycle where you live

So – is recycling worth it?

I feel passionately about the improving the plastics system and improving the recycling system, and I know that many of you reading this will feel that too. Recycling really does make a difference. We’ve come a long way, and there’s still work to be done – but the recycling system is improving for the better.

Let’s keep up the good work – it is worth it.

Could deposit return schemes turn the tide of plastic pollution?

Posted on by

For decades, plastic has been regarded as something of a miracle product. Lightweight, durable and versatile, it’s been used for practically everything, from food packaging and water pipes to aircraft and insulation systems.

But all of a sudden it seems that plastic has become public enemy number one.  In January, the Iceland supermarket chain announced plans to eliminate or drastically reduce plastic packaging of all its own-label products by the end of 2023. Also in January, the UK government set out its ambition to eliminate all avoidable plastic waste within 25 years.

A rising tide

The new war on plastic is largely to do with an increased awareness about the highly damaging impact of plastic waste on the planet. Research has found that, since the 1950s, nine billion tonnes of plastic has been produced, a figure that’s likely to rise to 30 billion tonnes by the end of the century. Over eight million tonnes of plastic enter the oceans each year, threatening marine and bird life, as well as having a wider impact on human health.

The difficulty of disposing of plastic waste has been amplified by China’s decision last summer to ban the import of 24 categories of recyclable materials, including most plastics. The news was a body blow to the waste management sector, which has relied on China’s dominant position in recycling to dispose of plastic waste.

Tackling the problem, one bottle at a time

More recently, the focus has been on single use plastic bottles for water and other soft drinks. The House of Commons Environmental Audit Committee last year reported that 13 billion plastic bottles are used each year in the UK. Only 57% of these are recycled, with the rest going to landfill/incineration or litter.

Various solutions have been suggested to reduce plastic bottle waste, such as greater provision of public drinking fountains and bottle refill points.

Another idea is the development of deposit return schemes (DRS). These involve consumers paying a small deposit on top of the price of a bottled drink. The deposit is refunded when the bottle is returned to an in-store collection point or a reverse vending machine. The bottles are then collected and recycled into new plastic bottles.

A 2015 study by Eunomia for Zero Waste Scotland considered the feasibility of a DRS being introduced to Scotland. The research included case studies of deposit return schemes in Germany and Scandinavia. In Germany, the introduction of the deposit on one-way beverage packaging was a big success with 98.5% of refillable bottles being returned by consumers. And in Norway, 96% of bottles are returned for plastic recycling.

The Eunomia study concluded that none of the challenges posed by introducing a DRS to Scotland was insuperable, and in September 2017, First Minister Nicola Sturgeon announced plans for a Scottish DRS. Shortly afterwards, the Commons Environmental Audit Committee recommended the introduction of a DRS in England, arguing that it would recycle more plastic bottles, save money and create jobs in the long run.

Deposit return schemes – pros and cons

Writing in the January 2018 ENDS Report, Dominic Hogg, chairman of Eunomia, described four benefits of DRS:

  • The return rates can be high, and the climate change benefits associated with recycling the materials are correspondingly higher;
  • Because materials returned are of a high level of purity, they are sought after by reprocessors;
  • Because they now have meaningful value, the rate of littering of used beverage containers falls by about 95%
  • A DRS would reduce the prevalence of plastic found in the marine environment.

However, some local authorities have expressed concern that they would lose money as people would use the DRS rather than recycle through local authorities’ kerbside systems.

Reservations have also been voiced by the soft drinks sector. AG Barr believes that “…the scope for fraud in a Scottish DRS is huge. On a small scale we could see people scavenging in bins for containers, as is the US experience. On a medium scale there is the potential for local authority amenity centre looting. And on a larger scale there is the very real possibility of cross-border trafficking of deposit-bearing containers.”

However, having previously opposed DRS, one major soft drinks company has undergone a change of heart. “A well-designed DRS, targeting the littering of on-the-go soft drinks, could have a role to play alongside reforms and improvements for the current systems,” said Nick Brown, head of sustainability at Coca-Cola European Partners.

A future role for plastic

While there is a growing recognition of the need to manage plastic waste, there’s also an understanding that plastic can’t simply be uninvented.

WRAP (the Waste and Resources Action Programme), which promotes sustainable waste management, has recognised the value of plastic as a resource:

“Take health care, for example. Most disposable medical items – insulin pens, IV tubes, inhalation masks, and so on – use plastic as a core component because it is sterile and reduces the risk of infection. Plastic packaging preserves and protects food. According to the US Flexible Packaging Association (FPA), plastic film extends the shelf life of a cucumber from three days to 14.”

Even so, it’s clear that we’ve reached a watershed moment concerning DRS. As Dominic Hogg concludes:

“Policymakers should make it clear that this is going to happen. The naysayers can choose either to be part of the solution’s design or to have it imposed upon them.”

From big data to creative ‘binfrastructure’: new ideas for tackling litter

Posted on by

As we’ve previously reported, litter is a big and expensive problem for the UK’s local authorities. A 2015 report by the House of Commons Communities and Local Government (CLG) Committee put the annual cost of cleaning up litter in England at around £850m. Litter also generates strong emotions. Research by Populus has found that 81% of people are angry and frustrated by the amount of litter lying all over the country.

The CLG committee and the UK government have put forward a range of proposals for tackling litter. But at home and overseas local authorities and the third sector have been looking at inventive ways to keep our streets clean.

 Philadelphia’s data-driven litter index

Earlier this year, Philadelphia’s Zero Waste and Litter Cabinet launched a digital tool to help catalogue the type and location of litter in the city’s neighbourhoods.

The Litter Index provides a full picture of the different types of waste in each of the city’s neighbourhoods, as well as recording the incidence of litter during different weather conditions. Using tablets, city workers record how much waste they’re seeing in their neighbourhoods, take photos and give ratings. The information can then be used to devise a plan for cleaning up litter in different parts of the city, and to pinpoint where resources are needed.

The Philadelphia plan is ambitious, but, as Nic Esposito, the city’s Zero Waste and Litter Director says: “If we’re not changing infrastructure and attitudes, we’re not going to solve the problem.”

 Edinburgh’s intelligent litter bins

New technology has been undergoing tests by the City of Edinburgh Council to measure how full litter bins have become and provide alerts via mobile when they reach capacity.

Sensors positioned inside the bins use ultrasonic technology to measure how full a bin has become. The data is then transmitted to notify the council’s waste management system when a bin needs emptied. The system can also help the council to spot fly tipping when there is sudden spike in the results, and a heat sensor detects fires inside the bin.

During the initial pilot project, collections in areas fitted with the new bins increased by 24% on average, and some collections quadrupled in frequency. The data from the sensors will be used to provide reports on waste generation patterns and can help in planning the most efficient routes for litter bin collections.

Driving litter underground

A growing number of European cities have invested in underground collection units in an effort to make their streets less cluttered.  In the Slovenian capital of Ljulbljana, these units are located around the city centre, with different receptacles for paper, glass, and packaging. In addition, residents of the city have access cards which open receptacles for organic and other specialist waste types, which in turn determines the level of their monthly waste management bill. Separation of waste in this way drives down the cost of managing it, and makes recycling much easier.

In the UK, Cambridge City Council has also taken an interest in subterranean waste units. Steel chutes have been set into the pavement with the aim of replacing thousands of wheelie bins. Residents have corresponding bins for their kitchens, which the city council believes will help create a sustainable living space.

Once completed, the 150-hectare site will have 450 underground recycling and general waste banks across 155 locations.

Thinking outside the bin

Environmental charity Hubbub has examined research and examples from around the world to develop a catalogue of creative and playful ideas for tackling litter effectively. Among the suggestions are:

  • an open-air gallery featuring local people to raise awareness of personal responsibility for waste management;
  • flashmobs to cheer on people who pick up litter and put it in the bin;
  • brightly-coloured bins that draw attention to litter campaigns; and
  • ‘talking bins’ that reward users with belches or coughs.

Hubbub has not confined its efforts to urban waste. Earlier this year, the charity unveiled a campaign targeting countryside litter. A “trashconverter” van toured the Forest of Dean, accepting trash, rather than cash, in exchange for flowers and hot drinks.

Final thoughts

As the Populus survey demonstrates, litter has a negative impact on how people view their own neighbourhoods. At the same time, as the recent Blue Planet 2 programme highlighted, our litter can have terrible effects on the natural environment and on birds and marine life, both in our own coastal waters and in oceans thousands of miles away.

Data, technology and behavioural insights all have important roles to play in tackling the blight of litter. Unusual initiatives, such as those employed in Philadelphia, Edinburgh and Cambridge, as well as Hubbub’s inventive ideas, are worth exploring if they can make an impact on human behaviour, and contribute to the conservation of the natural world.

Throwaway lines: poets celebrate the “hideous beauty” of landfill and the unsung heroes of waste management

Throwaway lines: poets celebrate the “hideous beauty” of landfill and the unsung heroes of waste management

Posted on by


If you think poetry is a load of old rubbish, you might find some agreement in the unlikeliest quarters. Poets themselves have been finding inspiration from the items we discard, and from the people who make a living clearing up our trash.

In October, John Wedgewood Clarke published a book of poetry called Landfill, the result of a year-long residency at two Yorkshire rubbish sites. The collection explores what John calls the “hideous beauty” of places that most of us would rarely describe as poetic.

The residency had a profound experience on the poet. Appearing on BBC Radio 4’s Today programme, John described the experience of making his way through the landscape of trash as akin to walking on the moon. And he found that landfill sites have their own seasons, with a blossoming of fairy lights just after Christmas and an upsurge in lawnmowers in the spring. In autumn the dump was littered with pumpkins and glow-sticks.

The collection features poems both about rubbish itself and its effects. Newsprint turns the writer’s skin grey, and he finds himself wandering through a “palace of glistering cans”.

A rubbish dump is also a repository for stories. One of the site workers told John about poignant finds such as discarded war medals and photograph albums.

In recent years, there have been greater efforts to divert more and more of our waste away from landfill. Many of us are recycling waste products, and the idea of a circular economy is becoming a reality.

In spite of these efforts, John’s rubbish residency is a reminder of the sheer scale of landfill, and of its enduring nature. As he told the Yorkshire Post: “our waste doesn’t disappear, it is simply on its way to becoming geology.”

Unsung heroes

In Edinburgh, the city’s Makar, Christine de Luca, has also found poetic inspiration from an unlikely source. A visit to the Seafield Waste Water Treatment Works resulted in a poem called Gardyloo which describes a space-station of engines, pipework and pumps that transform effluent into a purified stream which flows with “the speed and sparkle of a Highland burn in spate.”

Later, Christine persuaded a selection of poets to celebrate other Edinburgh workers whose service for the city largely goes unnoticed or unappreciated. The result was a collection of poems called Edinburgh Unsung, now freely available on Edinburgh City Council’s website.

The subjects are varied, from chimney sweeps and environmental wardens to facilities managers at the Scottish Parliament and book dusters at the National Library of Scotland. Christine herself, more used to writing in praise of the great and the good, such as Robert Louis Stevenson and James Clerk Maxwell, contributed a poem celebrating Edinburgh’s refuse collectors. It describes their daily routine of waste collection and disposal as a kind of dance, with its own repertoire, rhythm and precision.

A strange beauty

Percy Shelley described poetry as “a mirror which makes beautiful that which is distorted”. Many would have thought it impossible to equate the workings of a waste water treatment plant with something beautiful. But, as Christine de Luca, John Wedgewood Clarke and many other poets have demonstrated, there is a strange beauty in the features and functions of the everyday. And if these poets can – even for a moment – shine a light on the people working to make our lives better, then that’s kind of beautiful too.

Coming unstuck? New solutions to tackle discarded gum

Posted on by

In April, the Local Government Association (LGA) declared war on chewing gum:

“Chewing gum is a plague on our pavements. It’s ugly, it’s unsightly and it’s unacceptable.”

Representing more than 370 councils in England and Wales, the LGA called on chewing gum manufacturers for more support in tackling the £60m annual cost of removing discarded gum:

“Chewing gum manufacturers must help more with the growing multi-million pound cost to local communities of removing discarded gum, with 99% of the nation’s main shopping streets now spattered.”

A growing market, a costly problem

Chewing gum may be a modern-day product, but its origins go back a long way. The ancient Greeks, Aztecs, Mayans and Chinese all chewed substances made from the extract of plants and trees. But it was the commercial development of chewing gum in the United States in the 1860s that launched an international market that has continued to grow.

Today, sugar-free gum is marketed as a healthy alternative to confectionery and tobacco, with claims of added benefits, such as fresher breath and whiter teeth. Research in 2015 forecast a 32.6% rise in global chewing gum sales to reach $32.63 billion by 2019. Britain’s chewing gum market is seventh in the world.

All of which means that as more gum is being consumed, more is being discarded on city streets. Research by Keep Britain Tidy has found that 99% of main shopping streets and 64% of all roads and pavements are stained by chewing gum. And once a piece of gum hits the ground, it’s likely to remain there. Gum is made from synthetic plastics that don’t biodegrade, so it can only be addressed by costly removal techniques, such as steam cleaning.

As the LGA has pointed out, councils have no legal obligation to clear up gum once it has been flattened onto the ground. Even so, many councils have mounted gum cleaning operations to make the streets more attractive and improve the environment for residents, visitors and businesses.  But local authorities find themselves under increasing budgetary pressures, and are keen to find alternative solutions.

Taking action

Established in 2009, Gumdrop Ltd is the first company in the world to recycle and process chewing gum into a range of new compounds that can be used in the rubber and plastics industry.

Its eye-catching receptacles (also called Gumdrops), are made from recycled chewing gum, and placed in public places for the collection of gum that would otherwise litter the streets. Once full, Gumdrops and their contents are recycled and processed to make new Gumdrops.

The company has been working with public and private organisations to install their receptacles in railway stations, shopping centres, airports and universities, and has also formed links with chewing gum manufacturers. In partnership with Cardiff Council and Keep Wales Tidy, Gumdrop joined forces with The Wrigley Company Ltd. in 2013 to locate bins across the city centre and key district shopping centres. Siân O’Keefe, Senior Manager, Corporate Affairs at Wrigley, believes the project is a good model for others to follow.

“Encouraging behaviour change is the only long-term and sustainable solution to the problem of littered gum and we are totally committed tackling this issue”.

 Another initiative aiming to promote a gum-free environment is Keep Britain Tidy’s Chewing Gum Action Group. This campaign unites local authorities, central government and the chewing gum industry to encourage responsible disposal of gum. The group’s annual promotion encourages councils to run corresponding local campaigns across the UK. In 2016, the 11 local campaigns saw a 36% average reduction of dropped gum in monitored areas.

Meanwhile, one inventive individual in London is making a virtue of an eyesore by creating miniature works of art, with chewing gum as his canvas.

Final thoughts

Chewing gum waste is not just a problem in the UK. Across the world, authorities are looking at different approaches to deal with it. As of yet, there’s no sign of the UK following the lead of Singapore in banning the sale of chewing gum. Instead, national and local governments are trying to find less authoritarian ways of tackling this modern-day blight.

The progress made by Keep Britain Tidy, Gumdrop and others in the public and private sectors is to be applauded. But, as the LGA has made clear, gum manufacturers are now being expected to do a lot more, both by switching to biodegradable gum and contributing to the cost of clearing it up.

“While awareness campaigns the industry is involved in have some value, they are not enough by themselves. The industry needs to go a lot further, faster, in tackling this issue.”

ReGen Villages: is this the future of sustainable living?

The Netherlands covers an area of 41,543 km², and has a population of 17 million people. That works out at 488 people per square kilometre, making Holland the most densely populated country in the European Union. By comparison, the UK has a population density of 413 people per sq km, while the figure for Scotland is just 68 people per sq km

Statistics like that matter when it comes to waste management. Lack of space in the Netherlands has prompted successive governments to divert waste from landfill, and encourage more recycling. The waste management movement was strongly influenced by Ad Lansink, a chemistry lecturer turned politician, who developed “Lansink’s Ladder”. This tool has six “rungs”, with disposal on the bottom, then recovery, recycling, reuse and on the top rung prevention.

The Dutch approach has reaped impressive benefits, with high rates of recycling and most of the remainder being incinerated to generate electricity and heat.

However, there is a growing sense that recycling in the Netherlands may be close to its limit. In 2015, Green Growth in the Netherlands reported that since 2000, the percentage of recycled waste has remained more or less constant.

“Recycled material reached 81% in 2012, a high share that has been fairly constant over the years. This may indicate that the recycling percentages are close to their achievable maximum.”

The Dutch are now looking for further ways to create more value from recycled waste.

ReGen Villages

One such idea is the development of  “regenerative villages” (ReGen). These self-reliant communities will produce their own food, generate their own energy and recycle their own waste.

The ReGen model is the brainchild of California-based ReGen Villages, which is partnering with EFFEKT, a Danish architecture practice, to launch a pilot version in the Netherlands this year. 

Each ReGen community will contain a variety of homes, greenhouses and public buildings, with built-in sustainable features, such as solar power, communal fruit and vegetable gardens and shared water and waste management systems.  The five principles underpinning the concept are:

  • energy positive homes,
  • door-step high-yield organic food production,
  • mixed renewable energy and storage,
  • water and waste recycling,
  • empowerment of local communities

The first 25 pilot prefabricated homes will be located at Almere in the west of Holland. Almere has experienced exponential growth, rising from farmland in the 1970s to become the seventh largest city in the Netherlands.

Waste management is a key element in the ReGen villages, which will have  ‘closed-loop’ waste-to-resource systems that turn waste into energy.

Prospects and problems

There are plans to roll out the model in other communities, in Europe, North America and the Middle East. Off-grid communities are not a new idea. But the necessary technology, falling costs and consumer demand have reached a point where the ReGen approach may become truly sustainable. The idea offers the promise of meeting the challenges of rising populations making unprecedented demands on limited resources.

Interviewed in The Guardian, Frank Suurenbroek, professor of urban transformation at the Amsterdam University of Applied Sciences, acknowledged the need for such projects, but also highlighted potential problems:

“A possible field of tension is how the technological demands of sustainability and circularity [interact with] spatial configurations needed to create attractive places and the desire to create new houses fast. Both worlds have to learn how to connect. Experiments with new sustainable quarters are interesting and needed, but a major issue is how to do this within existing built areas.”

All eyes on Almere

Once the first 25 homes are built, a further 75 will complete the village. It will take a lot of time, money, skill and muscle to make the project a success . We’ll be watching with interest to see if the vision can be turned into reality.
