Circular Economy Podcast - 94 David Peck – navigating Critical Raw Material risks

94 David Peck – navigating the risk of Critical Raw Materials

David Peck, Associate Professor at TU Delft, explains why we need to know more about critical raw materials – what they are used in, and how we might navigate the future challenges they present.
David Peck is Associate Professor, Climate Design & Sustainability, Circular Built Environment and Critical Materials, Faculty of Architecture and the Built Environment, at Delft University of Technology (TU Delft).
David researches and teaches in the field of circular design, focusing on remanufacturing and critical materials. He is a founding member of the Circular Built Environment Hub and works cross disciplinary on circular challenges, in particular on digital, ICT, mobility and renewables fields.
David explains how critical raw materials are defined, helping us understand why they are ‘critical’ from the perspective of different countries or regions, and how they are assessed and scored.
We discuss the pressure on CRMs, particularly from the perspective of low-carbon technologies, and how this presents ethical dilemmas around ‘fair shares’ for countries, and even across different industry sectors.
I ask David about the conversations he’s having with businesses and policymakers, and whether he’s noticing positive trends towards a good understanding of CRMs, and a recognition of the complex issues and risks.
We discuss the ethics and other issues around mining, and David unpacks the dangers of over-simplifying the arguments for avoiding more mining.

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 - Ep90 Does circular mean sustainable?

90 – Does circular mean it’s sustainable?

Does circular mean it’s sustainable? Or, are companies just using circular economy solutions to grow their business (and their footprints)?
In this episode, I want to shine a light on something that’s been worrying me.
Over the last few years, I’ve come to realise that the circular economy is not fit for purpose. It’s not helping create the future we need. Instead, it’s being watered down, and cherry picked. I’m seeing increasing numbers of businesses and policymakers choosing strategies that ARE circular – but aren’t improving sustainability. I’m going to be talking about loopholes, rather than loops…
I think we’re at a critical turning point. We need to evolve the circular economy into a framework that supports the future we want – the future we know is possible.
If we don’t, we’re letting all our work, our innovations, our struggles, go to waste. (And you don’t need me to remind you that waste shouldn’t exist in a circular economy!)

Circular Economy Podcast Ep89 Simon Hombersley - Xampla

89 Simon Hombersley – plastics from plant protein

Simon Hombersley, CEO of Xampla, shares the story of how this Cambridge University spin-out has created the world’s first plant protein material for commercial use, pioneering the replacement of the most polluting plastics with natural alternatives. Xampla’s ambition is to become the leader in natural polymers, and it’s been developing its natural polymer resin over the past 15 years. The polymer, which Xampla describes as a breakthrough material, performs just like synthetic polymers, but decomposes naturally and fully without harming the environment at the end of life.
Xampla is the first UK University spin-out to be awarded B Corp status and is working with multi-national companies, including Britvic, Gousto and Croda on new technologies.

Circular Economy Podcast Episode 88 Alexandra Rico-Lloyd - the Bike Club

88 Alexandra Rico-Lloyd – the Bike Club

Alexandra Rico-Lloyd is one of the UK’s circular economy entrepreneurs, and is passionate about inspiring the next generation to get active and outdoors.
Alexandra says there are over 12.5 million unused kids bikes, just in the UK. That spurred her on to create Bike Club back in 2016, to provide a better way to cycle; better for the environment, better for parents and their children.
Bike Club has revolutionised the traditional model of ownership, aiming to change family cycling forever. It’s had over $40million of funding and reached 40,000 cyclists so far, and Bike Club says that makes it the largest micro mobility network in the UK – larger than Uber and Santander Cycles (what we used to call Boris Bikes).
Alexandra, who was recently listed in the Forbes 30 Under 30 list, shares the story of how the Bike Club grew from a self-funded ‘minimum viable proposition’, with a few bikes packed into an attic spare room. She explains how it’s delivering deeper levels of value for customers, and how its collaboration with one of the UK’s leading retailers has opened up its next development phase.

Circular Economy Podcast - 87 Veena Sahajwalla High-value MICROFactories

87 – Veena Sahajwalla – high-value opportunities from MICROFactories

Professor Veena Sahajwalla, founder of UNSW SMaRT Centre, is an internationally recognised materials scientist, engineer, and inventor who is revolutionising recycling science. In 2018, Veena launched the world’s first e-waste MICROfactorieTM and in 2019 she launched her plastics and Green Ceramics MICROfactoriesTM, another breakthrough for recycling technology. Veena unpacks the concepts of micro-factories and micro-recycling, and we hear why it’s important to get clear on the constituent materials in waste flows – for example, not just textiles, but what the textile is made from.
Veena explains the importance of thinking beyond the manufacture of the recycled material, so you are designing solutions that are properly suitable for high-value end-products. Veena also describes how the projects are collaborating with industry partners, helping open up opportunities for important local jobs, skills and resilient income streams.

Circular Economy Podcast 86 Jennifer Hinton - Rethinking how profit is used

86 Jennifer Hinton – Rethinking how profit is used

We explore a different way of thinking, about how business fits into our society and economy. Jennifer Hinton is a systems researcher and activist in the field of sustainable economy. Her work focuses on how societies relate to profit and how that relationship affects global sustainability challenges.
Jennifer started developing this theory in the book How on Earth, which outlines a conceptual model of a not-for-profit market economy – the Not-for-Profit World model.
As an activist, Jennifer collaborates with civil society organizations, businesses, and policy makers to transform the economy so that it can work for everyone within the ecological limits of the planet. Jennifer holds a double PhD in Economics and Sustainability Science, and is a researcher at Lund University and a senior research fellow at the Schumacher Institute.
