A compost heaps isn’t just the place at the bottom of a garden where you scrape the leftovers from supper – there’s a whole lot more than unwanted food that can compost.

5 Things You Didn’t Know You Could Compost (from My Zero-Waste Kitchen, by Kate Turner)

composting cardboard

You might be used to recycling your unwanted cardboard packaging – such as egg and cereal boxes, and toilet and kitchen roll tubes – but did you know that you can rip them up and add them to your compost heap?

composting wine corks

Don’t bin that cork once you’ve popped it! Cork is a natural product that can be added to compost. Do watch out for synthetic corks that have been made to look like the real thing though – plastic will not break down in your compost heap.

composting wine and beer

Don’t pour sour wine or flat beer down the sink, they are great for compost. Both are rich in nitrogen and beer contains yeast for good microbes to feast on. Keep an eye the moisture levels of your compost, if it’s dry then add the liquids but if it’s wet add dry material too, such as shredded paper, to balance it out.

composting stale snack food

Old crisps, crackers, and biscuits will break down fast in a compost heap, but be sure to bury them deep within the heap as they can attract unwanted visitors to your garden.

composting cupcake cases

Paper cupcake or muffin cases can be added to your compost heap where they will break down quickly. Do watch out for any waxy-feeling cases that may contain an element of plastic, which you shouldn’t compost. If in doubt, leave it out!
