My city collects waste food for composting. There is /no seeds/ rule, likely because whoever uses the compost wants to control what they grow.
I make veg. broth by boiling veg. scraps for ~30—60 min., some of which are loaded with seeds. I’m wondering if the boiling kills the seed, in which case I wouldn’t likely cause problems by tossing the boiled scraps into the city’s compost.
Technically, proper composting itself should be hot enough to kill off any seeds. Boiling should definitely be good enough. My guess is they don’t want people just loading up the compost with weedy yard waste
