Facing the continuous increase of global waste generation，with the development of economy and society，the improvement of waste management system and the enhancement of public awareness of environmental protection，the establishment of “waste-free city” has become the planning goal of more and more countries and cities. Starting from 2017，China began to launch the “Zero waste city” construction pilot project，to make breakthrough progress in key areas and key links of solid waste and to form replicable and replicable demonstration models. The demand for sound management of solid waste is continuously increasing，the disposal demand of many stocks of solid waste will be released，and the speed and scale of related investments will be further improved. In particular，the recycling and treatment industry of key types of solid waste in the life field commonly faced by various cities，such as construction waste，kitchen waste，household waste incineration and waste lead acid battery，will receive more opportunities and support for development.
