What Is the Best Use of Biomass? A Harmonized LCA‐TEA Framework Quantifying Economic and Environmental Metrics for Bioenergy Pathways

GCB Bioenergy, Volume 18, Issue 5, May 2026.
A harmonized LCA and TEA framework evaluates 19 bioenergy pathways, quantifying carbon intensity (CI), minimum fuel selling price (MFSP), and marginal abatement cost (MAC). CCS reduces CI to net‐negative values and lowers MAC by up to 64%, with bioelectricity achieving the lowest MAC and liquid biofuels critical for hard‐to‐abate sectors.

Production of Alcohols from C1-waste Gas Fermentation by Clostridium carboxidivorans in a Continuous Gas Fed Bioreactor

Chemical Engineering Transactions
Syngas – a gas mixture of CO, CO2, and H2 – can be produced by gasification of C-based streams (e.g. biomass, plastics). It is as a cost-effective substrate for the production of numerous valuable products.
