It’s a familiar frustration, ordering something small, only for it to arrive in a box far bigger than it needs; wasteful and seemingly impossible to avoid. This week, we’re joined by Jude Pullen, a man on a mission to change that. Join us as we explore why companies so often get packaging wrong, uncovering the logistical challenges behind every delivery, and discover how Jude is using a blend of creativity and engineering to tackle this surprisingly complex problem.

Last month, Netflix released The Plastic Detox, which we reviewed in Episode 86, and it left us with a lot of questions. One of the film’s featured participants, Eric Isaac, got in touch to let us know he could help fill in the gaps. So instead of a back-and-forth over email, we invited him onto the show. Join us this week as we go behind the scenes of this groundbreaking documentary, unpacking what the couples really did to remove plastic from their lives, what didn’t make the final cut, and the realities of trying to live plastic-free.

With more than 160,000 followers on TikTok, Ashley might just be the most famous binman in the UK. In this episode, we sit down with the biggest binfluencer to talk about life on the rounds and how he built an online following by sharing the realities of the job. We also take a closer look at how bin collections actually work across the UK and hear first-hand what makes the job rewarding, challenging, and sometimes surprising. Ashley shares practical tips on how households can make life easier for refuse crews, reduce contamination in recycling, and play their part in helping waste services run smoothly. It’s a behind-the-scenes look at a vital public service that most of us rely on every week, but rarely think about.

Much of the plastic packaging we use every day contains colours and additives that can be harmful, and that often prevent the plastic from being recycled at all. This week’s guest, Steven Burns, has spent years tackling that problem by developing ways to remove colour and additives from plastic, increasing its value and usability and making it far more likely to be recycled. In this episode, we explore how the process works, its potential to improve environmental outcomes, and how it could help reduce health concerns linked to plastic recycling.

In 2021, Ellie and James left their jobs and spent 15 months travelling around the world. Along the way, they paid close attention to how sustainability showed up in practice; what worked, what didn’t, and what felt worth questioning. In this New Year’s episode, Ellie joins Robbie and James to reflect on the trip. They revisit it continent by continent, each sharing one idea or observation that stuck with them. The conversation covers travel, perspective, and what they took away from the experience.

With nearly 200,000 tonnes of direct carbon emissions linked to the UK TV and film industry in 2024, sustainability is quickly becoming an urgent priority. This week’s guest, Stephanie Shires, has helped deliver major carbon-reduction initiatives on some of the biggest shows currently on television. She offers a behind-the-scenes look at how environmental impact is managed on set, from food and transport, to accommodation and daily logistics. Steph breaks down the practical decisions she faces each day, revealing what it really takes to make modern productions more sustainable.

With over 17,000 islands, 34,000 miles of coastline, and limited formal waste management, Indonesia faces an immense waste challenge, one that’s compounded by imports of foreign waste from countries like the UK. This week’s guest, Esther Carter (recently named #1 on the Resource Hot 100), shares insights from her time living and working in Indonesia, offering a first-hand perspective on how the crisis unfolds on the ground. In this wide-ranging conversation, we dig into the realities of waste management across the archipelago, the social and environmental impacts of global waste trade, and explore what meaningful solutions could look like for Indonesia’s future.

Over 160,000 households across 10 local authorities have been trialling flexible plastic collections. The early results are promising: strong participation, positive resident feedback, and low contamination rates. But while 400 tonnes have been collected so far, that figure pales in comparison to the estimated 150,000 tonnes expected once all councils are required to collect this material from 2027. Gareth Morton from Ecosurety joins us to explain how the system will scale to meet this surge, and what lessons we can take from the pilots already underway.

This week’s guest, Saabira Chaudhuri, author of Consumed: How Big Brands Got Us Hooked on Plastic, takes us on a fascinating journey through the meteoric rise of plastic. From the quirks of history that propelled it past every rival material, to the boardroom decisions that sealed its fate, we uncover how plastic became the world’s go-to choice, and what we might do differently if we could start again.
