collection, transportation and recycling of kitchen waste.

1. Collection and transportation of kitchen waste. Guangdong Province selected several demonstration villages, set up several small-scale decentralized kitchen waste treatment equipment, and carried out waste sorting work in selected places.

2. recycling. The kitchen waste in Guangdong is separated into pulp and solids by large-sized sorting and thermal hydrolysis, and then the pulp and solids are separated by squeezing pulping technology, and the solids are transported to the incineration plant outside the factory for treatment. The high-concentration organic pulp is first treated by anaerobic fermentation, and the biogas generated by fermentation is purified to generate electricity, which can also be made into natural gas.
