It is roughly industrially as follows:

1. carrying out three-level crushing on the kitchen waste to enable the particle size of the waste to be not more than 7 mm;

2. continuously sterilizing for about two hours at the high temperature of 120 ℃;

3. fermenting for about 36 hours;

4. centrifuging to obtain solid and liquid; drying the solid to obtain industrial protein; the liquid is separated in a butterfly way to obtain industrial crude oil, alcohol (condensed at 105 ℃) and water, and the water is purified to reach the discharge standard and then discharged or recycled.

While this approach is relatively mature and practical, it has the following problems:
