Raise worms.

Condensed and expanded from articles on StopWaste.org and WikiHow.com

Worm compost bin: Approx. 10 to 16 inches deep (24 inches max); 2 square feet per person w/ small holes on the sides so the worms can breathe, and a tight lid.

Bedding: non-glossy newsprint. Cut into 1-inch strips, moisten with water (but not sopping wet) and fill bin three-quarters full. Optional additions: shredded cardboard, dirt, leaves, sawdust, straw.

Ventilation: Drill several 1/8 inch holes in bottom of bin and in the sides, approx. 4 inches from the bottom.

Cover: The bin should have a cover to prevent light from getting in and to prevent the compost from drying out.

Worms: 1 lbs. of Eisenia fetida (red wigglers) per square foot. Add a quart of scraps and wait two weeks. After that, feed about a quart a week.

First compost ready in two to three months.
