DEVELOPMENT OF ASSESSMENT MODEL FOR BIOMASS UTILIZATION MEASURES IN CHINA -A CASE STUDY IN ZHEJIANG PROVINCE-

Abstract

  In this paper, the practical model was developed to examine a supply-demand balance of biomass at a province level in China and assess the effect of biomass utilization systems on life-cycle GHG emissions reduction. Applying this model to Zhejiang Province in China, we also evaluated the effect of reductions in GHG emissions, mineral resources consumption, and land use through the following two alternative options of biomass utilization: Energy conversion and material recovery. The results showed that the amount of GHG emissions reduction in energy conversion case would be 31.4Mt-CO₂, 1.8 times larger than material recovery case. On the other hand, material recovery case could save 1.6Mt of phosphate rock, 0.6Mha of farmland and 1.6Mha of artificial forest.
