How to Build Worm Compost Bins


Composting is a good way to turn your vegetable-based food waste into a rich compost. By composting, you reduce the volume of waste going to the landfill and create a good organic fertilizer. Worm composting is faster than traditional composting and takes far less space. Worm composting can be done indoors in the winter, although you may want to keep the bin in the basement or a heated garage.

Step 1

Drill 1/8-inch holes in the top, sides, and bottom of one of the bins.

Step 2

Glue plastic screening to all inside surfaces of the bin with holes. This will keep the worms from escaping while allowing air to flow through the holes.

Step 3

Place two bricks lengthwise in the bottom of the bin without holes. This will allow air to flow properly around the inner bin.

Step 4

Slip the bin with holes into the one with the bricks.

Step 5

Cut scrap paper into one-half to one-inch strips.

Step 6

Dampen the paper and put it in the bin with holes.

Step 7

Add red worms. Add about a half a pound of vegetables and paper per week per pound of worms.
