Develop a supporting framework to select waste treatment solutions for supper-intensive shrimp farming based on combining material flow analysis and life cycle assessment

This study aims to assess the current status of emissions and propose waste treatment solutions for super-intensive shrimp ponds.Then, a framework to support the selection of waste treatment solutions in super-intensive shrimp ponds is built based on the material flow analysis (MFA) method combined with life cycle assessment (LCA).The MFA method is applied to analyse and evaluate the flow of materials and waste in shrimp production, from farming to waste treatment.Meanwhile, LCA helps quantify the impacts of proposed solutions on the environment and ecosystem.The results have selected and demonstrated waste treatment solutions in an integrated ecological model for super-intensive shrimp ponds.Greenhouse gas emissions reached 24,600 kgCO2 eq, acidification reached 219.5 kgSO2 eq, eutrophication reached 315 kgPO4 eq, cumulative energy use CEU=307.5 kg C, and net primary productivity BRU reached 303,500 kg C released into the environment in shrimp farming activities.
