What if waste is just material that has lost its way?
In this episode of HappyPorch Radio, we go back into the archive to our 2023 conversation with Christian van Maaren, founder and CEO of Excess Materials Exchange, and Anne Rademaker of Rademaker Consulting. First published in Season 7, it comes with a new introduction from Barry on what has changed since.
Excess Materials Exchange works like a dating site for secondary materials and waste. It gives materials an identity through resources passport, then uses technology to match them with their highest-value next use. But as Christian and Anne explain, the technology is only part of the story. Making it work means changing processes, contracts and incentives, and getting departments that have never worked together to collaborate.
A lot has moved on since 2023. Digital product passports are now becoming EU infrastructure, Right to Repair rules apply across the EU, and sustainability reporting has been scaled back. As Christian told us when we asked about republishing, it's no longer only about sustainability, but about resource security, supply chains and the financial case.

You drop off your engagement ring to be repaired. You get a handwritten paper ticket. No confirmation, no updates, no idea when it's coming back. For something with that much value, it's a stressful experience. And for everyday items, that same friction is often enough to make people skip the repair and buy new instead.
In this episode of HappyPorch Radio, Barry O'Kane speaks with Emily Watts, founder and CEO of Coblr, a company building the digital infrastructure to connect and power the repair economy for the first time.
Emily spent years in corporate operations, was COO of a scheduling startup that sold to Toast, and then did something unusual: she ran her own mail-in repair business for two years, not as the endgame, but to understand the problem from the inside. What she found was an industry running on software from the early 2000s, brands managing repair manually even at scale, and consumer intent dying because the process was just too much hassle.
Her thesis is simple. She compares repair to resale: shopping secondhand used to mean sorting through racks at a charity shop. Technology removed that friction and the market exploded. Emily believes repair is sitting in the same place right now, with the demand already there but held back by a broken experience. Coblr's job is to fix the experience.

What happens when unwanted laptops and phones become more than just an e-waste problem?
In this episode of HappyPorch Radio, Barry O'Kane speaks with Elaine Brown, Chief Executive of The Edinburgh Remakery, a social enterprise and charity working at the intersection of technology reuse, repair and community support.
The Remakery takes unwanted technology from businesses, securely wipes and refurbishes it, and gives it a second life wherever possible. But its mission goes beyond keeping electronics out of landfill. The organisation uses circularity to create social value too, supporting people experiencing digital exclusion, creating opportunities to learn repair skills, and providing a space where communities can come together. Earlier this year, The Remakery won a King's Award for Enterprise, the only social enterprise in Scotland to be recognised.
Elaine is candid about the challenges too, including what happens when funding falls away and a growing organisation has to find new ways to sustain itself.

The tailoring workforce in the US has been shrinking for decades. And the ones that remain aren't easy to find or get an appointment with.
In this episode of HappyPorch Radio, Barry O'Kane speaks with Robin Atkinson and Cash Acrey, the husband-and-wife co-founders of Upkept, an online clothing repair platform based in Northwest Arkansas. You mail in clothes you want fixed, they repair them in a centralised facility, and they send them back. Robin says this should be as easy as ordering delivery.
Robin's journey began with a different question: how do you create meaningful sewing jobs in America? Along the way she discovered something unexpected. The people learning these skills weren't excited by repetitive manufacturing. They loved repair, where every garment is different and every project demands creativity and problem-solving.
That insight sits at the heart of Upkept: the technology isn't the product. Repair is the product, and the software exists to reduce friction so the human craft can scale.

👤 About our guests:
Robin Atkinson is the founder and CEO of Upkept, an online apparel repair and alterations platform serving customers across 26 US states from a centralised facility in Northwest Arkansas. After nine years building workforce development programmes in sewn trades, she founded Upkept to create meaningful skilled jobs while making clothing repair affordable and accessible. She describes her mission as getting the unit economics of repair to work in America.
Cash Acrey is the CFO and CTO of Upkept and a finance professor at the University of Arkansas. He leads the company's technology strategy, building custom software from scratch using AI coding tools that simplifies the repair experience for customers while supporting the skilled people carrying out the work.

Most commercial kitchens have no clear picture of what they are throwing away, when, or why.
In this episode of HappyPorch Radio, Barry O'Kane speaks with Anastasia Dellis, CEO of Orbisk, a platform that uses AI and computer vision to make food waste visible in commercial kitchens. The Orbi monitor sits above a waste bin, captures every item discarded, recognises over 800 ingredients, and feeds it all into a dashboard that tells chefs, GMs, CFOs, and sustainability teams what is happening and what to change first.
Anastasia's path to Orbisk runs through two decades of scaling businesses, from Africa's largest retailer to Gorillas, one of Europe's fastest-growing startups in quick commerce. She describes recognising the intersection of her professional experience with a personal connection to food scarcity she grew up with in South Africa.
What comes through most clearly is her conviction that kitchen technology only works at scale if it demands nothing of the people using it. No training, no buttons, no extra steps. That principle, which Orbisk calls "No Pause Dispose," is not an afterthought; it is the product.

The same handbag. Thirty different platforms. Hundreds of dollars between listings. And no way to know what it's actually worth.
In this episode of HappyPorch Radio, Barry O'Kane speaks with Chris Lucas, founder and CEO of Secondsense, a platform that aggregates luxury resale listings from over 30 vendors, normalises their attributes, and tells consumers what a product is really trading at. Chris describes it as the Google Flights for luxury resale.
Chris's background is unusual for the fashion space. Stanford AI, senior machine learning engineer at Instagram, then Harvard Business School. He built a prototype while still a student, a TikToker put it on her channel, the site crashed overnight, and Chris opened a fundraise the next morning. He didn't wait until the product was ready. He didn't wait until he graduated. He just ran.
What's most striking about the conversation is Chris's view on where value sits now. He argues the modelling layer, the application layer, and the hardware layer are all effectively democratised. Someone can duplicate a website in minutes using tools like Lovable or Claude Code. The only thing that can't be replicated is years of clean, structured, proprietary data and the domain expertise to know what to do with it. For Secondsense, that means knowing that a caviar leather Chanel sells differently from lambskin, or that champagne hardware changes the price, details a layperson would never spot.

Chris grew up in a family of entrepreneurs and describes his mission as making the resale market efficient, determining the fair market value of any product in any condition.

Technology isn't magic. And neither is the bin, even though most of us treat it like one.
In this episode of HappyPorch Radio, Barry O'Kane speaks with Tom Passmore, CIO and co-founder of Dsposal, a company that has spent a decade building technology for the UK waste sector. Tom has a vivid way of describing the core problem: the moment someone decides they don't want something, it's dead to them. All the nostalgia, all the value, gone. It goes to the magic away place.
But what actually happens in that magic away place matters enormously, and the UK has something most countries don't: roughly 10 years of structured public waste data. Dsposal's work is about joining that data together, building tools on top of it, and helping organisations move from simply complying with waste regulations to genuinely understanding what's happening with their waste and why.
Tom is unusually candid about the pace of change. A customer portal his team built sat untouched for eight years before usage suddenly accelerated post-COVID. The data didn't change. The questions did. And that shift, from asking what and where to asking why, is where Tom sees real change beginning.
The conversation also gets into the UK government's new Digital Waste Tracking programme, where Tom plays the role of critical friend, broadly supportive of the direction but direct about the gaps, particularly around who gets to see the data and whether phase two will track waste or just the vehicles carrying it.

👤 About our guest:
Tom Passmore is the CIO and co-founder of Dsposal, a web platform that has spent 10 years making waste management easier, more transparent, and more compliant for organisations across the UK. Dsposal works with universities, NHS trusts, science parks, local authorities, and small to medium waste management companies, connecting public waste data with tools that help users find legal waste outlets, track compliance, and increasingly drill into the why behind their waste patterns. Tom is an active voice in the UK waste data community, serves as a critical friend to DEFRA's Digital Waste Tracking programme, and is passionate about the untapped potential in the UK's public waste datasets.

Technology isn't magic. But sometimes dropping your spoon in a bowl of soup during a pandemic leads you somewhere extraordinary.
In this episode of HappyPorch Radio, Barry O'Kane speaks with Thierry Sanders, founder of Kolekt, a platform connecting waste collectors, buy-back centres, and recyclers across the Global South. Thierry's background spans fintech, microfinance, and living in developing countries from Ecuador to Pakistan to Indonesia, and Kolekt grew directly out of two weeks spent riding around Bali on a motorbike with informal waste collectors, learning how their world actually works.
What makes Kolekt's story unusual is the order of operations. Thierry didn't arrive with a product looking for a market. He started with cigarettes, lunch, and genuine curiosity, and the technology followed the problems he discovered: collectors wasting half their time searching for materials that weren't there, workers without phones or bank accounts locked out of digital systems, and facial recognition tools that didn't work for the people who needed them most.
The conversation is direct about the harder edges of this work: the fossil fuel industry flooding markets with cheap virgin plastic, governments demanding surveillance data on immigrant workers, and the gap between EPR policy and what actually reaches the people doing the collecting.

Thierry Sanders is the founder of Kolekt (kolekt.com), a platform that connects waste collectors, buy-back centres, and recyclers across the Global South. With a background in fintech and microfinance across developing countries including Ecuador, Pakistan, and Indonesia, Thierry built Kolekt after spending two weeks with informal waste collectors in Bali during the pandemic, learning how the waste economy works from the ground up. Kolekt now operates in Indonesia, Vietnam, Brazil, Mozambique, Kenya, and Ghana, with around 14,000 active waste collector profiles and close to 100,000 transactions processed. Thierry also advises governments across South Asia on Extended Producer Responsibility legislation and has developed Kolekt's EPR compliance platform for Mozambique.

Technology isn't magic. And neither, it turns out, is circular strategy.
In this episode of HappyPorch Radio, Barry O'Kane speaks with Amelia Woodley, a sustainability leader with 25 years of cross-sector experience, and Vin Sharma, a researcher whose doctoral work examined why the social dimension of circular economy so often gets left behind.
Amelia introduces her "logic versus magic" framework: the logic side covers strategy, systems, KPIs, and measurement; the magic side covers the storytelling, brand identity, training, and people-led change that make sustainability mean something inside an organisation. Her argument is that most organisations over-invest in the logic and underinvest in the magic, and that is exactly where circular transformations stall.
Vin's research adds depth to this picture. Across companies at different stages of their circular journey, he found that social value tends to be bolted on rather than built in, and that the organisations making genuine progress were the ones who treated crises as learning events rather than problems to recover from.
The conversation is unusually direct on the financial dimension. Both guests push back on the idea that circular solutions come with a green premium: with good data and whole-life cost thinking, the commercial case can be made. The challenge is building the analytical and organisational muscle to make it properly.

👤 About our guests:
Amelia Woodley is a sustainability leader with nearly 25 years of experience designing and embedding sustainability strategies across sectors including construction, rail, infrastructure, nuclear, and retail. She has led major circular economy and net zero transformation programmes and is a strong advocate for making circular thinking accessible and commercially credible inside organisations.
Vin Sharma is a researcher whose doctoral work examined how organisations integrate social value into circular economy transitions. His research identified consistent patterns across companies at different stages of circular maturity, and proposed frameworks for understanding how reactive responses to crises can build long-term capability.

Technology isn’t magic. And neither is circularity.
In this episode of HappyPorch Radio, Barry O’Kane speaks with Lieke van Kerkhoven, co-founder of Green Pulse.
Lieke explains how Green Pulse is helping hospitals extend the life of medical equipment by connecting them with a global network of buyers. The platform combines logistics, marketplace dynamics, and technology to make reuse viable in a complex and highly regulated environment, an example of what we mean by Exploring circular tech: technology isn’t magic, where technology plays a role, but only as part of a much bigger operational and human system.
They discuss the practical realities of building a circular business, from managing operations and growth to creating trust between buyers and sellers. The conversation also explores a broader idea: how businesses can move beyond treating sustainability as an add-on and instead integrate it into their core commercial model.
The episode highlights Lieke’s concept of “integrative business”, the role of AI in reshaping work, and the importance of aligning incentives across the value chain.
