Abstract: Due to the shortage of land resources in China, the mainstream treatment process of domestic waste has changed from landfill to incineration, and the proportion of incineration disposal had reached more than 50%. The accurate analysis of calorific value of waste, as the key factor of whether waste could be incinerated, is of great significance. The dry-base high caloric value determination and C, H, O, N, S, Cl content analysis of thirteen kinds of rubber and plastic, eight kinds of fabrics, eighteen kinds of paper, thirty kinds of kitchen waste and eight kinds of wood and bamboo single components were realized by using bomb calorimetric method and analytical methods of elemental analyzer. The calorific value test results showed that the dry-base high calorific value data scale of rubber and plastic, fabric, paper, kitchen waste and wood and bamboo were 20 790~48 228、16 903~37 854、10 046~16 923、15 704~26 434、16 082~26 932 kJ/kg, respectively. It was also found that the dry-base high caloric value was mainly positively correlated with the content of carbon and hydrogen, and negatively correlated with the content of oxygen.
