Kitchen waste mainly refers to leftovers, leftover rice, peels, eggshells, tea residues, meat bones, etc.

Kitchen waste refers to the garbage generated in residents' daily life and activities such as food processing, catering services, and unit catering, including discarded vegetable leaves, leftovers, leftover rice, peels, eggshells, tea residues, bones, etc.

The main sources are home kitchens, restaurants, restaurants, canteens, markets and other food processing-related industries.

Kitchen waste contains extremely high moisture and organic matter, which makes it easy to decay and produce stench.

After proper treatment and processing, it can be converted into new resources. The high organic content allows it to be used as fertilizer and feed after strict treatment. It can also produce biogas for fuel or power generation. The oil part can be used to prepare biofuels.

Experimental tests have found that the moisture content in kitchen waste is as high as 74% and it is easily fermented.

Leaving it for a long time will, on the one hand, pollute the indoor air.

Catering waste is prone to contain a variety of highly infectious pathogenic bacteria such as Salmonella, Staphylococcus aureus, and Mycobacterium tuberculosis. If not cleaned in time, it will emit odor or even "toxic gas" after decay, polluting the indoor environment.

On the other hand, it also poses a variety of health risks.

Many pathogenic microorganisms in food waste are often "nutritional kitchens" for mosquitoes, flies, and cockroaches. Mosquitoes bite the skin and inject saliva into the human body, which can spread diseases such as malaria and Japanese encephalitis; flies have 1,700 microorganisms on their body surface

There are tens of thousands of bacteria that can spread more than 30 diseases such as typhoid fever, hepatitis, and tuberculosis. Cockroaches carry more bacteria, produce smelly secretions, and reproduce quickly.

Extension information The way to deal with kitchen waste must first be classified.

Separate food waste from other types of garbage, and sort and discard it at designated points during the garbage disposal process, thereby facilitating the subsequent processing of food waste.

Secondly, try to reuse kitchen waste, such as turning vegetable peels into environmentally friendly enzymes, and turning animal offal, oil, etc. into compost for planting flowers and plants.

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

This garbage machine can crush food waste such as peels, vegetable leaves, and eggshells and add microbial inoculants to make compost.

The compost produced can be collected by specialized composting plants for a fee. On the one hand, it reduces the production cost of the composting plants. On the other hand, it can also turn the food waste generated in households into treasure.
