The simplest method. Build or buy a bin, layer greens and browns, turn periodically. A minimum size of 3'x3'x3' (1 cubic yard) is needed to generate and retain enough heat for effective decomposition.
Home Composting
Turn kitchen scraps into garden gold. Five methods compared, from apartment-friendly worm bins to large-scale hot composting.
Greens (Nitrogen-Rich)
- Fruit and vegetable scraps — Cut large pieces for faster decomposition
- Coffee grounds and filters — Excellent nitrogen source. Unbleached filters preferred
- Tea bags (remove staples) — Some tea bags contain polypropylene — check brand
- Eggshells — Crush finely for faster breakdown. Add calcium to soil
- Fresh grass clippings — Add in thin layers to prevent matting. Mix with browns
- Plant trimmings — Chop into small pieces. Avoid diseased plants
- Seaweed and kelp — Rinse to remove excess salt. Excellent mineral source
- Hair and fur — Decomposes slowly but adds nitrogen
- Fresh weeds (without seeds) — Only if pile reaches 140°F+ to kill seeds
- Manure (herbivore only) — Chicken, rabbit, horse, cow. Age before use on edibles
Browns (Carbon-Rich)
- Dry leaves — Shred for faster decomposition. Excellent carbon source
- Cardboard (torn, uncoated) — Remove tape and plastic. Soak to speed breakdown
- Newspaper (shredded) — Modern newspaper ink is soy-based and safe. Avoid glossy inserts
- Paper towels and napkins — Only if chemical-free. Skip if used with cleaning products
- Wood chips and sawdust — Untreated wood only. Sawdust is very high carbon — use sparingly
- Straw and hay — Straw preferred (less weed seeds than hay)
- Dryer lint (100% natural fibers) — Only from cotton/wool loads. Synthetic lint = microplastics
- Pine needles — Acidic — use in moderation. Slow to decompose
- Corn stalks and cobs — Chop into pieces. Cobs decompose very slowly
- Nut shells (not walnut) — Walnut contains juglone, toxic to many plants
Composting Methods

An enclosed, rotatable drum mounted on a frame. Tumbling aerates the compost without manual turning. Sealed design deters pests and retains heat and moisture better than open bins.

Red wiggler worms (Eisenia fetida) consume food scraps and produce castings (worm poop), one of the richest fertilizers available. A pound of worms can process half a pound of food scraps per day.
Time: | Effort: | Best for:
An anaerobic fermentation process using inoculated bran (Effective Microorganisms). Unlike traditional composting, Bokashi can handle meat, dairy, and cooked food. The fermented material is then buried in soil to complete decomposition.

Many cities now offer green bin programs that accept food scraps, yard waste, and sometimes compostable packaging. Industrial facilities reach 140-160°F, killing pathogens and weed seeds that survive home composting.
