Techno-economic Analysis and Life-Cycle Analysis of Renewable Diesel Fuels Produced with Waste Feedstocks

Longwen Ou et al.

Summary: This study explores the economic and environmental implications of using wet waste feedstocks to produce biofuels, focusing on two pathways from yellow grease and swine manure. The swine manure HTL pathway shows negative GHG emissions due to credits of avoided emissions from conventional swine manure management. The commercialized yellow grease HEFA pathway benefits from carbon credits in the California Low Carbon Fuel Standard market.

Biofuel Options for Marine Applications: Technoeconomic and Life-Cycle Analyses

Eric C. D. Tan et al.

Summary: This study evaluates the economic feasibility and emission benefits of various biofuel production pathways compared to conventional marine fuels. The results show that biofuels can effectively reduce greenhouse gas and pollutant emissions from the maritime shipping industry at a lower cost. Cofeeding biomass with natural gas could be a practical approach to transition to biofuels with lower marginal CO2 abatement costs.

Life cycle analysis of renewable natural gas and lactic acid production from waste feedstocks

Uisung Lee et al.

Summary: Producing fuels and chemicals from waste is economically and environmentally favorable, with renewable natural gas and lactic acid showing significantly lower carbon intensities compared to conventional pathways. Life cycle analysis helps identify greenhouse gas emission hotspots and emission savings sources, supporting decisions for sustainable waste valorization.
