This week, Alasdair and Jane take a deep dive into what happens when a car reaches the end of the road. With around 1–2 million end-of-life vehicles scrapped in the UK each year, it’s a massive waste stream — and it’s becoming even more complex as modern vehicles contain more plastics, electronics, composites, and hazardous components than ever before.

They explain that scrapping a vehicle isn’t as simple as crushing it into a cube. Before anything else happens, cars must be deregistered and taken to an Authorised Treatment Facility (ATF), where the first priority is depollution. That means safely removing fluids like fuel, oils, coolant and brake fluid, along with batteries, airbags, and other hazardous parts. As Jane points out, airbags are effectively explosive devices — so there’s a very real safety process behind dismantling vehicles properly.

The episode also explores the growing role of reuse, with “green parts” now commonly used by garages and insurers. Instead of fitting brand new parts, repairers can source working components from scrapped vehicles — saving money and keeping materials in circulation for longer. It’s a great example of circular economy principles already working well in practice.

Finally, they touch on the trickier end of ELV recycling: the leftover “frag” or shredder residue that remains once the metals have been recovered. This mixed material can contain plastics, foams, small metals and contaminants, and it’s often harder to treat or recycle — raising questions about what happens to the last difficult fraction once the high-value materials are removed.

Rubbish Rant: Plastic Film – Too Soon?

This week’s rant focuses on Scotland’s Duty of Care consultation, which includes proposals around requiring commercial premises to start segregating plastic film. While the ambition is clear, Alasdair questions whether the system is ready — arguing we still struggle to properly manage the plastic streams we already collect, so adding another challenging material could be putting the cart before the horse.
