Over the past two years, 30 batches of kitchen organic waste materials have been tracked to  nd out how to use it ef ciently in Shanghai. The components of the raw materials were analyzed; meanwhile, scholars conducted a composition study on kitchen waste. The results show that the impurity rate of organic kitchen waste is high. Mainly nitrogen contained in the raw materials of organic kitchen wasted. And also, Salt content (Na+ ) and crude fat content were high in the organic kitchen waste. 12 batches of kitchen organic waste products were analyzed. After deoiling and desalting of high-temperature biochemical products of kitchen organic waste the nutrient became lower than the raw materials. The salt content (Na+ ) and crude fat content of these products were higher than standard organic fertilizer, and the germination index (GI) was lower. If the oil and salt barrier factor should be overcome by strictly sorted and classi ed, the kitchen organic waste can realize resource utilization.
