Abstract: In order to better practice and implement Beijing municipal waste classification requirements， waste samples from typical institutions and areas in Beijing were selected， in order to analyze the physical composition and characteristics difference of MSW in different functional areas. The results of cluster analysis showed that the MSW from subway station， hypermarket， office area， culture and education area and gymnasium in typical units， and the MSW from business district， business culture and education areas as well as roads in typical areas clustered in two types， characterized by more recyclable waste content， which could be approximately classified into recyclable and non-recyclable waste. The residential areas， tourist attractions， squares， hotels in typical units and rural areas， cottage areas， high-end residential areas， gas and heating areas， tourist areas and square areas in typical areas clustered in three types， characterized by a large amount of kitchen waste， which could be roughly divided into kitchen waste， recyclable waste and other waste. Therefore， the effective utilization of kitchen waste and recyclable waste could achieve the reduction and recycling of MSW to the greatest extent.
