can you compost tin cans?
No — food cans are lined steel; they rust rather than rot, taking decades while shedding sharp flakes and a plastic liner into the pile.
which bins can take it?
- hot pile no
- cold pile no
- worm bin no
- bokashi no
- tumbler no
- curbside no
why?
A 'tin' can is steel wearing a micro-thin tin or polymer coat, and most food cans add an epoxy liner to keep contents off the metal. None of that is biodegradable — oxidation, not digestion, is the only force that touches steel, and a buried can needs roughly 50 years to rust away while its liner survives as a film of plastic.
how to prep it
- Rinse cans and drop them straight into curbside recycling
what to do instead
Rinse and recycle — steel is among the most recycled materials in the country, and magnets pull cans out of the sorting stream automatically, so nearly every can you bin gets recovered.
often confused with
- Aluminum beverage cans — Soda cans are aluminum, not steel — equally recyclable, equally non-compostable, but sorted as a different metal at the facility.
quick answers
Do I need to remove the paper label first?
Not for recycling — labels burn off in the melt. If you like, peel the paper label off and compost it; that one part of a can genuinely is pile-worthy.
Are can linings still made with BPA?
Most US canmakers switched to non-BPA epoxies and acrylics starting around 2016, but the replacement liners are still plastics. Whatever the formula, the liner never decomposes.
