TL;DR: In this paper, a life cycle assessment (LCA) is performed to evaluate the environmental impacts and resource intensity of producing rare earth oxides (REO) from the Bayan Obo mine located in Inner Mongolia, China.

TL;DR: Given the high variability in microalgae’s energy and environmental performance, careful evaluation of the algae-to-fuel supply chain is necessary to ensure the long-term sustainability of emerging algal biofuel systems.

TL;DR: In this paper, the energy return on investment (EROI) and life cycle greenhouse gas (GHG) emissions for producing algal derived biodiesel and renewable diesel under different production pathways were modeled.

TL;DR: Analysis reveals that the energetic performance and GHG reduction potential of fast pyrolysis-derived fuels are highly sensitive to the choice of coproduct scenario and LCA allocation scheme, and in select cases can change the life cycle carbon balance from meeting to exceeding the renewable fuel standard emissions reduction threshold for cellulosic biofuels.

TL;DR: In this article, a well-to-wheel life cycle assessment (LCA) model is developed to characterize the life cycle energy consumption and greenhouse gas emissions profiles of a series of novel multistage torrefaction and pyrolysis systems for targeted thermochemical conversion of short rotation woody crops to bio-oil and in situ catalytic upgrading to hydrocarbon transportation fuels.
