Not much introduction, I can't understand. Just look at your answer 1.5 hours to degrade 400 kilograms of garbage.

Look at your understanding of degradation. Plastic bags will degrade for more than 100 years, that is, to the molecular state. According to this understanding, it is impossible for 1.5 hours to degrade 400 kilograms of garbage. If possible, all landfills can be replaced.

Look at the picture, just say that it is reduced by 90%. It can only be said that solid-liquid oil-water separation has been done, but the water content has decreased and relatively dry garbage has come out.
