We live in a relatively urban area in an apartment with zero land that we can compost traditionally on. As voracious plant-eaters we have quite a lot of vegetable scraps that we morally can't send to the landfill. The solution is a worm bin that resembles furniture, won't stink up the place if properly managed, and can process the waste of at least two plant-chomping people.
These instructions will show how to construct a three-tiered, wooden worm bin out of readily available materials. In the future we will cover how to add and care for the wormies.
How does it work?
The three-tiered system works like a magic food to compost machine. The three boxes are identical and interchangeable. You put food scraps and woody material (paper, wood shavings, etc.) into the top layer which worms eat over time, filling the top box. Once the top layer is nearly full, you put the empty bottom layer on top. Then once that layer is nearly full you put the last empty box on top. By the time that one is full you will have premium, beautiful soil in the bottom layer that can be emptied out and used. The cycle keeps going. The layers are important because the worms will seek refuge, rest, and reproduce toward the bottom.
Since the layers are identical, the directions will show how to make one box, the base, and the lid.
The worm bin is ventilated and will ONLY smell bad if it is poorly managed. It should smell like the floor of an old growth forest. More on how to achieve that to come.
