Food Waste Disposal

The first step is to categorize the waste. Separate food waste from other types of garbage and dispose of them at regular intervals during the garbage disposal process, so as to facilitate the subsequent disposal of food waste.

Secondly, try to make secondary use of food waste, such as vegetable peelings and other environmental enzymes, animal offal, oil and grease into compost, used to grow flowers and plants.

According to People's Daily, an Italian environmental research institute recently developed a "new organic waste sustainable treatment machine", which is also called a "garbage-eating machine".

The machine can make compost by crushing fruit peels, leaves, eggshells and other food waste and by adding microbial agents. The compost can be collected by specialized composting plants for a fee, which on the one hand reduces the production cost of composting plants, and on the other hand can turn the food waste generated in households into treasure.
