Review of Life Cycle Assessment Studies on Resource-oriented Utilization of Swine Manure
摘要
Abstract
In China,pig manure represents a significant source of agricultural non-point source pollution.The resource utilization of pig manure encounters challenges such as the disconnection between crop cultivation and livestock breeding,inadequate operational mechanisms,and the absence of comprehensive evaluation systems.As a full-chain systematic assessment instrument,life cycle assessment(LCA)can comprehensively encompass the entire"collection-treatment-utilization"process of pig manure.It functions as a crucial tool for systematically evaluating environmental,economic and social benefits and has manifested an irreplaceable role in promoting the scientific and standardized development of pig manure resource utilization.Scholars both at home and abroad have also carried out extensive research using LCA.For instance,they have analyzed the environmental impacts of different manure treatment technologies and compared the economic efficiency of various treatment modes.Nevertheless,current studies possess several limitations.There are inconsistencies in the definitions of system boundaries and functional units,which influence the comparability of results.The environmental evaluation indicators are overly simplistic.Regional differences and implicit costs are inadequately considered in economic assessment,and there is a lack of localized LCA databases.Looking forward,future research should focus on 3 major directions as follows:standardize system boundaries,broaden the research scope to cover the entire industrial chain while emphasizing key links.It should enrich evaluation dimensions by introducing social-LCA(S-LCA)and optimize assessment methods by constructing localized models and enhancing databases,so as to offer support for the scientific development of pig manure resource utilization.关键词
