Economic and Environmental Assessment of Straw Direct-fired Power Generation

摘要

A cost combined life cycle assessment was carried out to estimate the economic and environmental impact of corn straw direct-fired power generation. Results showed that the road transport, diesel, and infrastructure stages represented the dominant contribution to environmental impact in most midpoint categories, whereas the tax, depreciation, raw materials, and infrastructure price played an important role to economic impact. Improving raw material consumption efficiency and decreasing the direct emissions (i.e, nitrogen oxides and sulfur dioxide) generated from electricity production stage are the efficient way to minimize overall environmental or economic impacts.
