141 Joel Tasche: scaleable solutions to plastic pollution

Joel Tasche founded CleanHub, a Berlin-based company that provides a scalable solution to plastic pollution. CleanHub connects coastal communities to proper waste collection in places where that doesn’t exist, at the same time creating safe and dignified jobs. Brands can support the mission by funding the collection of waste that otherwise wouldn’t be collected. CleanHub accepts ALL types of plastic – not just the stuff that’s easy to turn into value. CleanHub’s AI technology tracks the entire process from collection to disposal, ensuring transparency. It’s verified by TÜV SÜD according to ISO standards
Joel’s mission was sparked by a love of the ocean. As a traveler and surfer, he witnessed firsthand the heartbreaking reality of plastic pollution, everywhere he went. Whilst disheartened, Joel resolved to dedicate his working life to keeping plastic out of the sea. Many doubted he could make a difference. Fast forward to today, CleanHub has collected over 9 million kgs of plastic waste and partnered with more than 300 brands, helping them reduce plastic and collect more plastic than they use.
Whilst we see images of ocean plastics, beach plastics and landfills, we’re perhaps less familiar with the dreadful working conditions of those trying to earn a living by collecting and sorting the waste. Resolving this is at the heart of CleanHub’s mission, and we’ll more about how it does that.
Joel also talks about the complexities of plastic waste collection, how to scale new ventures, and how keeping ethics at the heart of your business really helps bring everyone along with you.

136 Julia Brenner of Melta: creating value from food waste

There is a simple solution to conserve, and reuse, more of the nutrients from food waste.
In today’s episode, I’m talking to Julia Brenner, a soil scientist and co-founder of Melta, a company dedicated to transforming waste management and soil health. Julia and her business partner founded Melta in 2020, to solve two interconnected challenges faced by rural municipalities: the lack of accessible and cost-effective food waste solutions, and the difficulty of transporting organic fertilizers to remote areas.
This is a brilliant example of something that is needs little investment, saves money, time and space, and can be adopted easily, all around the world. It is easy to scale out, and a great example of a local, regenerative solution to the typical ineffective, expensive and resource-intensive solutions that we see in western society.
The Melta system uses the Bokashi process which is thought to originate from East Asia, centuries ago. The Bokashi process converts food waste and similar organic matter into a nutrient-rich soil additive which also improves soil texture.
Melta’s innovative system for organic waste collection, processing, and utilization can reduce municipal waste transport by 70%, and producing a nutrient-rich fertilizer that is cheaper and easier for farmers to access.
Julia studied soil restoration at the University of Iceland and then delved further into nutrient cycling and climate models at Oak Ridge National Laboratory. She continues to engage in collaborative field experiments with the Soil Conservation Service of Iceland and Icelandic Agricultural University. Julia is passionate about making “sustainability” a realistic and attainable goal, and is committed to bridging the gap between practical waste management and soil health.
We discover why dealing with household food waste is such a big headache for rural municipalities; and how the bokashi process can easily become part of a system that’s better for households, farmers and the local council.
Julia explains how the Bokashi process works in practice, and why households prefer it over other methods like putting food waste in with other refuse, or have separate food waste collection bins. As we’ll hear, the results are amazing – and the system is very simple, so it could be easily used in rural areas around the world.

Circular Economy Podcast 97 Alice Mah - Unpicking plastic propaganda

97 Alice Mah – unpicking plastics propaganda

IT’S EPISODE 97, and today we’ll be talking about plastics, a familiar circular economy topic, from someone with a someone with a less familiar background… Alice Mah is Professor of Sociology at the University of Warwick, in the UK, and she’ll help us unpick the propaganda about plastics and their role in a circular economy
I came across Alice’s work when IEMA’s Transform magazine interviewed her about her latest book, Plastic Unlimited: How Corporations are Fuelling the Ecological Crisis and What We Can Do About It. I’m a member of IEMA, which is the Institute of Environmental Management and Assessment. Alice unpacked some of the ways the plastics industry is trying to improve our perception of plastics, including how it tries to reframe the circular economy as a recycling issue. She highlighted other worrying aspects of how the petrochemicals industry is operating, and we’ll hear some of those.
Spookily, a few weeks later, on the same day I’d emailed Alice to invite her on, I was in the kitchen half-listening to BBC Radio 4’s sociology programme, Thinking Allowed, and up popped Alice, being interviewed about the ways the plastic industry uses its corporate power to influence our thinking around plastics.
Alice Mah holds a PhD in Sociology from the London School of Economics and was Principal Investigator of the large-scale European Research Council project “Toxic Expertise: Environmental Justice and the Global Petrochemical Industry” from 2015-2020. Her research focuses on environmental justice, corporate power, and the politics of green industrial transformations. Her next book the is Petrochemical Planet: Multiscalar Battles of Industrial Transformation.
In today’s conversation, I’ve asked Alice to help bust some myths around plastics and their potential role in a circular economy…
Myth #1 Plastics can support a Net Zero economy
Myth #2 Plastics are safe – in other words, it’s wrong to link plastics to health issues
Myth #3 Plastics are essential for our quality of life
Myth #4 Exporting plastic waste to low-income countries helps the country, and/or the local people, create value from that plastic
Myth #5 Plastic recycling can play an important role in the circular economy.

We’ll hear how online retailing has transformed the market for mattresses, and led to increased levels of returns. Nick explains the complexity of mattress designs, and how TFR Group is going beyond recycling to help its customers recover more value from unwanted mattresses.
Nick describes the broader circular services and advice offered to The Furniture Recyclng Group’s clients, and what makes mattresses such a challenging product to reuse or remake, including barriers created by our sub-conscious perceptions.

Circular Economy Podcast 95 - Simone Andersson - social value from circular e-waste solutions

95 Simone Andersson – social value from circular e-waste solutions

Simone Andersson is Chief Commercial Officer at WEEE Centre, a Kenyan social enterprise that’s been expanding safe e-waste management and circular solutions across East Africa, since 2012. Simone’s background is in communication and sustainability action around waste and water management, and before joining the WEEE Centre she was at RISE (Research Institutes of Sweden), where she led innovative developmental projects on resource efficiency, circular economy systems, traceability, precious materials and various solid and liquid wastes.
Her mission is to create awareness about the possibilities and prosperity of Green Business and Clean Tech.
The WEEE Centre focuses on people, planet and prosperity, in particular by helping young people improve their social and economic circumstances. It’s aiming to expand the collection infrastructure to cover all Kenyan Counties and to increase local recycling by bringing more advanced technologies. It also wants to reach other African countries, starting with neighboring Uganda and Tanzania.
By 2019, the WEEE Centre had recycled more than 10,000ntons of e-waste, serving over 8,000 clients across Africa, and creating hundreds of jobs. It became the first and only e-waste management organization to be ISO certified with multiple awards. WEEE Centre has the capacity to recycle all types of e-waste, and has trained many other African countries on safe e-waste recycling.
We’ll hear about the operational complexities, some of the collaborations and partnerships they’ve fostered to overcome the challenges of being a relatively small enterprise, and how they’re trying to make sure they create value-adding circular flows, rather than focusing on recycling.

Circular Economy Podcast - Ep93 Guglielmo Mazza ReFuse Eco

93 Guglielmo Mazza – helping communities refuse packaging waste

Guglielmo Mazzà is an environmental engineer and social entrepreneur, and the co-founder and CEO of ReFuse, a social enterprise based in Beirut [Lebanon] that offers community-based solid waste management services. Guglielmo worked in development initiatives and humanitarian response in the field of water, sanitation, hygiene and financial inclusion, across Europe and Africa. His passion is combining equitable access to resources with ecosystem justice and restoration.
ReFuse has a mission to work with underserved communities, enabling them to sort recyclables and get rewarded for it. ReFuse says: “Where most people see a pile of waste, we see opportunities to improve the lives of vulnerable people. Secondary raw-materials have an unexploited value.”
Guglielmo explains some of the issues faced by many people living in Beirut, where approximately one-third of the population are migrants, with many living in temporary tented communities. Poverty, inequality and lack of government funds are big issues, and there is a lack of basic infrastructure, including a reliable electricity supply.
We hear how the ReFuse operation works, how they’ve expanded the range of materials they can recycle, and what they do with it all. We find out what motivates people to bring their recyclables along to the ReFuse stations – surprisingly, for many people, it’s not about the cash.

Circular Economy Podcast Ep92 Elmar Stroomer Africa Collect Textiles

92 Elmar Stroomer – circular textile solutions in Africa

Elmar Stroomer is the founder of Africa Collect Textiles (ACT). Africa Collect Textiles does exactly that – collecting used textiles across Africa, for reuse, recycling and upcycling.

Elmar Stroomer has a strong background in the circular economy and design, and lived in Kenya and Uganda between 2012 and 2017 to get Africa Collect Textiles up and running. Now, Elmar is working full time on the expansion of ACT in Kenya and Nigeria. ACT aims to develop solutions to end the textile waste issues across Africa. It distributes free and affordable clothing to underprivileged communities, and currently has over 40 collection points in Nairobi and Lagos for used textiles. It provides employment to more than 50 people, who help collect, sort and upcycle fashion waste, used uniforms and off-cuts, creating products such as rugs, backpacks, toys and much more. On top of this, for every kilogram of used textiles it recycles, Africa Collect Textiles (ACT) donates 10 Kenyan shillings to charity. We hear about how fashion waste imported from the global north has undermined the existing textile and clothing sector in Kenya, and why Elmar decided to create a circular economy for locally produced textiles. Elmar tells us about some of the circular initiatives that ACT has set up, including repurposing workshops, services for resellers that overcome some of the major issues with the system for reselling imported end-of-use textiles, and innovative ways of repurposing end-of-life clothing for local businesses.
