Talking Rubbish - Recycled Content

Thanks to listener Tricia, who discovered us in the Radio Times, for asking about compostable Christmas card wrapping. We explain the difference between home compostable and industrially compostable packaging, why certification logos matter, and why most compostable plastics in the UK still belong in the general waste rather than food waste or recycling.

Chocolate advent calendars are recyclable, but only if you separate the cardboard, plastic and foil. While brands like M&S and Tony's Chocolonely have tried to reduce packaging, the best option is still a reusable advent calendar filled with your own treats each year, cutting waste and avoiding unnecessary packaging altogether.

Can brittle plastic bottles found during litter picks still be recycled? We reached out to the experts who explained  that PET bottles are extremely durable and weathered bottles are unlikely to cause problems in the recycling stream, even after years outdoors. However, Gareth notes that plastics which have become brittle, fragmented, and heavily contaminated with soil or vegetation are unlikely to be successfully recycled and...

Nitrous oxide canisters may be made of steel, but they are one of the biggest headaches for waste operators. Like batteries, they can explode or cause fires if crushed during collection and processing. Although recreational use was banned in the UK in November 2023, the canisters remain widely available and are still used legitimately for catering, motorsport and other hobbies. Whether small or large, they should never go in your k...

Buying new clothes isn’t always the greenest option. Re-dyeing faded black trousers with products like Dylon can dramatically extend their life, using around 60 litres of water compared with roughly 8,000 litres needed to produce a new pair of jeans. Research commissioned by Dylon suggests re-dyeing a pair of jeans can save nearly 20kg of CO₂ versus buying new. While fabric dyes do have some environmental impact, their footpr...

Are effervescent tablet tubes recyclable? To our surprise there were beads hidden in the lid. Those little silica beads are there to keep moisture out. The good news is that, according to recycling experts, the silica desiccant is compatible with polypropylene (PP) recycling and separates during processing. That means the tubes can be recycled as normal — definitely not rubbish.

Prompted by an email from listener Kenton, we revisit the paper-versus-plastic debate. While plastic pollution is a serious problem, we argue that the best choice depends on the product and propose three tests for "good" plastic packaging: it should be recyclable, contain at least 50% recycled content, and be significantly lighter than the alternative. Using these criteria, plastic wrap around recycled toilet roll may outperform pa...

Are stamps recyclable? Used stamps can be donated to charities, which sell collectable stamps to raise funds, although everyday stamps have very little value. If you're saving stamps, trim around them carefully, leaving about 1cm of envelope attached. As for stamp books, they're likely rubbish. Self-adhesive stamp backing paper is thought to be coated with silicone so stamps can peel away easily. Like greaseproof paper, this silico...

A Discord discussion prompted us to ask what happens to bagged recycling. During a recent visit to a SUEZ Materials Recovery Facility, we learned that bagged recyclables are often treated as contamination unless staff have time to open them, and some loads can even be rejected if too much material is bagged. While some facilities have bag-splitting equipment, using bags generally increases the risk that recyclable material won't be...

After spotting a discarded fire extinguisher in a Bristol woodland, we looked into how to dispose of expired extinguishers safely. They shouldn't go in your household bin because they're pressurised and may contain hazardous materials, including older foams with PFAS "forever chemicals". Bristol Waste explains that extinguishers can be taken to the Household Waste Recycling Centre, where they're handled separately as hazardous wast...

If you blow your nose on toilet paper, is it greener to bin it or flush it? We weigh up the trade-offs: incineration versus wastewater treatment, energy recovery versus water use, and even the surprising role flushed tissues can play in tracking disease outbreaks through sewage monitoring. Our conclusion: flushing probably edges it, but only if you're not flushing solely for the tissue. Wait until you're using the toilet anyway, an...

This week’s Rubbish or Not looks at Carex handwash refill pouches, which use 85% less plastic than bottles. Carex says the pouches can be recycled if you “snip to recycle”, but listener Alison struggled to find where. The answer lies in the Recycle Now locator used on the Carex website; these pouches are usually classified as either “cleaning pouches” or “plastic bags and wrapping” (flexibl...

When choosing aluminium foil, is it better to buy the one labelled "recyclable" or the one "made from recycled material"? In this episode, we unpack the difference between these two common claims and explore whether they're really telling consumers anything useful. We discuss why most aluminium already contains recycled content, why marketers choose one message over another, and whether recycled-content percentages should be displa...

Scratch cards have been around for decades, but are they rubbish or not? In this episode, we look at what scratch cards are made from, how the scratch-off coating works, and whether scratching it away creates microplastics. Using a National Lottery scratch card as an example, we explore its recyclability, the materials involved, and whether digital alternatives might be the better option for regular players.

This episode looks at pre-consumer recycling, inspired by a Paw Patrol toy labelled as being made with pre-consumer recycled plastic. Unlike post-consumer recycling, which uses materials collected from households, pre-consumer recycling uses manufacturing waste such as plastic offcuts and defective parts. We explore whether this should count as recycling or simply efficient manufacturing, and ask whether industrial scrap is truly w...

Are water pistols recyclable? Usually not in your kerbside recycling. Most are made from tough engineering plastics, likely ABS, which aren't commonly collected by local recycling schemes. If they're still usable, donation is the best option. If broken, your local recycling centre may be able to accept them.

Keep Britain Tidy estimates that around two million pieces of litter are dropped every day in the UK, with street cleaning costing taxpayers more than £1 billion annually. While most people understand that dropping rubbish can lead to a fine, the legal definition of litter is not always as clear-cut as it might seem. In this episode, we examine a case that challenged assumptions about what constitutes littering, exploring the legis...

The iconic red Solo cup, from its surprisingly useful measurement ridges and budget-friendly polystyrene construction to the challenges of recycling a product that remains a staple of American parties. We explore the environmental impact of these cups, why they're still so common, and how their story reflects broader questions about convenience, waste, and disposable culture.

Recycling is often criticised as a distraction from bigger environmental challenges, but is that really true? We explore the argument that recycling creates complacency and discuss why it remains an important part of a wider sustainability system. We examine the role of personal responsibility, policy, economics and behaviour change, and why reducing waste, improving recycling and tackling larger environmental issues are not mutual...
