Process and directly utilize, propagation and the infection of pathogen can be caused.(3) nutrient composition content enriches, and changing food waste is except organic
Outside thing content height, also rich in nitrogen, phosphorus, potassium, calcium and various trace element, have that nutrient is complete, recycle value is high
Feature, therefore resource should be implemented.
Utilize changing food waste to produce fertilizer and can use aerobic compost and anaerobic composting technology, by contrast, use anaerobism heap
Fertilizer technology processes changing food waste, can transfer to " environmental conservation " from " energy recovery ", more can fully make these changing food wastes reach
To resource, the innoxious and purpose of minimizing utilization, there is the advantage of its uniqueness.
In prior art, the major technique that compost is taked has biochemical anaerobic digestion and two step anaerobic digestions, raw by it
Produce biogas and electric power.
