Depends on how your system handles it. In Toronto, they basically pulp it all, put it in a vat of water and scoop off the plastics at the top and really heavy stuff at the bottom before letting it do it's thing in a sealed digester. As a result, they even accept diapers because they'll at least soak off the stuff worth composting. A last step is to heat it enough to kill off any pathogens. Also accepts meat/fish/bones. https://www.cbc.ca/news/science/organic-waste-composting-1.5291132 https://www.cbc.ca/news/science/organic-waste-composting-1.5... If your system is just throwing everything into a big piles getting mixed around ("aerated"), the rules get different. Another city that uses the classic "big piles" method had to ban grass clippings because they contributed to too much odour (too much nitrogen = lots of ammonia, but would've made great fertilizer) https://www.cbc.ca/news/canada/hamilton/green-bin-composting-1.4826899 https://www.cbc.ca/news/canada/hamilton/green-bin-composting...
