Here is a list of a few things that should not go into compost
- Pet waste such as cat or dog waste,
- Meat, cheese and general kitchen waste cooked food
- Perennial weeds, (and weeds with seeds if the heap is not heating up enough to kill the weed seeds).
Grass cutting are OK in the compost but not a huge heap of cuttings thrown into the bin or on the heap in one go.
