Present situation of hazardous waste generation in China and grey model prediction

Abstract

Abstract According to the 2008-2017 China Environmental Statistics Yearbook data, combined with GIS heat map, the current situation and regional distribution characteristics of hazardous waste generation and disposal in China were analyzed, and the GM gray model was constructed to predict its output in the next five years. The results show that it is predicted that by the end of 2023, hazardous waste production of China will reach 157,889,300 tons. It is suggested that take the government as the guidance, the production and disposal enterprises will jointly promote the development of hazardous waste resources, improve the existing treatment methods and strengthen the hazardous waste management system, thus breaking the deadlock of geographical mismatch.
