| Abstract: |
| With the fast development of agricultural economy in China, the quantity of crop straws and other wastes produced by plant industry, animal husbandry and human activities is instantly increased, an estimation of their quanti-ties and assoeiated methods converting to biogas production potential is critical to their rational evaluation and explo-ration. In this study, conversion coefficients of various agricultural wastes to biogas were determined by development of methods for evaluation of their biogas transforming potentials, and the total amount of agricultural wastes were estimated for the year 2009 in China. The results showed that the amount crop straws reached 8.99×108t, excrement and urine of beasts and birds 39.9×108 t, and the human being’s night soil 2.53×108 t. Their mash gas potentials were
estimatcd to be 5832.67×108 m3 in total, which is equivalent to 4.14×108 t SCE(standard coal equivalent). We conclude that the marsh gas resource potential of agricultural wastes is enormous in China, which is important to practical cycling econ-omy. |
