The aim of this study is to find potential utilization practice of rice straw in India from an environmental perspective. Life cycle assessment (LCA) is conducted for four most realistic utilization practices of straw including: (1) incorporation into the field as fertilizer (2) animal fodder (3) electricity (4) biogas. The results show that processing of 1 ton straw to electricity and biogas resulted in net reduction of 1471 and 1023kg CO eq., 15.0 and 3.4kg SO eq. and 6.7 and 7.1kg CH eq. emissions in global warming, acidification and photochemical oxidation creation potential respectively. Electricity production from straw replaces the coal based electricity and resulted in benefits in most of the environmental impacts whereas use as an animal fodder resulted in eutrophication benefits. The burning of straw is a harmful practice of managing straw in India which can be avoided by utilizing straw for bioenergy.
本研究旨在从环境角度探讨印度稻草的潜在利用实践。对四种最现实的稻草利用方式进行了生命周期评估（LCA），包括：（1）作为肥料还田，（2）动物饲料，（3）发电，（4）沼气。结果表明，将 1 吨稻草加工成电力和沼气，可分别减少 1471 公斤和 1023 公斤 COeq，全球变暖、酸化和光化学氧化产生潜能中的 15.0 公斤和 3.4 公斤 SOeq，以及 6.7 公斤和 7.1 公斤 CHeq 的排放。用稻草发电取代了基于煤炭的电力，在大多数环境影响方面都带来了益处，而将其用作动物饲料则带来了富营养化益处。在印度，燃烧稻草是管理稻草的一种有害做法，可以通过利用稻草生产生物能源来避免这种做法。
