can you compost floor sweepings?
Yes, but only what fell there naturally — crumbs, hair, and grit compost fine; pick out twist ties, foil, and plastic bits first.

which bins can take it?
- hot pile yes
- cold pile yes
- worm bin caution
- bokashi no
- tumbler yes
- curbside no
- worm bin: A spoonful now and then is fine; steady grit and hair build up fast in a small bin.
why?
Kitchen-floor sweepings are mostly crumbs, hair, dust, and tracked-in grit — the organic share rots quickly, and a little soil actually helps, since traditional compost recipes layered it in precisely to seed microbes. The trouble is that a broom collects whatever fell: twist ties, staples, plastic film shards, and glitter, which pass straight through the pile and into your beds.
how to prep it
- Pick out obvious plastic, foil, and metal before emptying the dustpan
- Skip sweepings from craft projects or workshop areas
- Keep litter-box spill and pet-accident cleanup out entirely
watch out for
- Glitter, foam beads, and plastic film shards vanish into the mix once dumped — don't compost sweepings from craft cleanup.
- Sweepings collected after using carpet or floor powders carry the product with them; trash those.
- Litter scattered around a cat box is pet waste, not floor dirt — Toxoplasma gondii oocysts survive in soil for a year and belong nowhere near a food garden, so bin those sweepings. Pregnant people should hand off litter-box cleanup entirely.
quick answers
Is the dirt and grit from sweeping good or bad for a pile?
A light dusting is genuinely useful — soil seeds compost with microbes and minerals, which is why old layered-pile recipes included it. Shovel-loads, on the other hand, smother airflow and add dead weight.
