If you drink beer from glass bottles, you can recycle the metal lids.
Each beer or kombucha lid is approximately 3 grams of steel. To put this in perspective, my favourite kitchen knife is also made of steel, and weighs 124g. A mere 41 bottle caps to make a knife!
For every tonne of steel we recycle, we save*:
- 1,131kg of iron ore
- 633kg of coal
- 54kg of limestone
Trouble is, metal beer lids are too small for many recycling facilities. The best way to recycle them is to collect them in a larger container of the same material to ensure they are captured and processed by the sorting equipment. But what could that be?
The way to tell if something is steel is to see if a fridge magnet sticks.
Food cans are made of stainless steel. I know, I know, BPA. Living dangerously, but realistically over here. We eat canned food occasionally. If you don’t have a tin around, I’m sure there’s one in your neighbour’s recycling.
We use an empty food can to collect beer caps. When the can is half full of lids, crimp the top to secure the contents and pop it in the curbside recycling bin. The concept of like-with-like works for aluminium as well.
