Abstract

Straw is the main resource of fuel for biomass power generation plants in China's agricultural areas. Field survey and emergy analysis were employed to investigate the operation situation of the straw collection, transportation and storage system based on the case of Laifa Straw Recycling Company. In the condition of collecting 2 × 108 kg of straw production, the emergy input of the artificial model of the company was 173.02 × 1018 sej, which was higher than the emergy input of the mechanical model, 148.11 × 1018 sej. According to the emergy indicator system, the mechanical model had a high development degree of internal resources and environment, high productivity, high sustainable development ability, but a lower proportion of renewable resource emergy input than the artificial model. The emergy value of 1 kg commercial straw calculated from the commercial price was 0.25 × 1012 sej, which was only one third of the average input of the company to produce 1 kg commercial straw (0.74 × 1012–0.87 × 1012 sej). It was difficult for straw recycling company to survive in the market due to the low price of the commercial straw. Therefore, the government was suggested to take effective economic policies to support local straw recycling enterprises.
