Degradable compost garbage is domestic garbage, which generally includes paper, wood, plants, food, feces, fertilizers, peels and so on. Garbage compost can improve the reuse of waste and generate value. After high-temperature composting, pathogenic bacteria will be reduced and harmful eggs will be killed. It is safer to use compost as organic fertilizer, but the waste treatment time is long and the waste reduction effect is poor. Long-term use is easy to cause soil hardening and groundwater deterioration.

Degradation of compost is to use microorganisms in garbage to explain when biochemical reaction occurs, thus forming substances similar to corrosive soil, which can be used as fertilizer and can improve soil well.
