Abstract Details

2019, Master of Science, Ohio State University, Chemical Engineering.
Conventional life cycle assessment method (LCA) has been used to compare environmental impacts between alternatives, which sheds some light in product optimization and environmental improvements. However, the role of ecosystems played across the life cycle of a product was not considered by LCA methodology, which actually matters much. To achieve absolute environmental sustainability, the ecosystems should be able to provide goods and services and cannot be adversely affected. The method techno-ecological synergy in life cycle assessment (TES-LCA) used in this study has enable the assessment of absolute environmental sustainability since demands and supplies of ecosystem services are considered while LCA cannot. The product studied in this study is soybean biodiesel. The functional unit assigned is 1 liter of biodiesel. Three ecosystem services are considered at multiple spatial scales: air quality regulation service, water provisioning and carbon sequestration services. The results indicate that only water provisioning service is environmentally sustainable at both local and serviceshed scale. Neither local nor serviceshed environmental sustainability can be claimed for biodiesel life cycle in carbon sequestration service and air quality regulation service (CO). The other three air pollutants considered for air quality regulation service: NO2, PM10 and SO2 are environmentally sustainable at local scale but unsustainable at serviceshed scale.
