Energy and Environmental Performance of Biodiesel Derived From Waste Vegetable and Animal Oils: Integrated Energy Balance, Process Optimization, and Feasibility Assessment

GCB Bioenergy, Volume 18, Issue 5, May 2026.
This study demonstrates a highly efficient biodiesel production route from waste vegetable and animal oils, achieving a net energy ratio (NER) of 7.8–8.2 and over 85% greenhouse‐gas reduction. Methanol recovery and optimized logistics enhanced energy efficiency, validating waste‐oil biodiesel as a sustainable circular‐bioeconomy fuel.

Emerging Technologies for Biobutanol Production via Syngas Fermentation

GCB Bioenergy, Volume 18, Issue 5, May 2026.
Biobutanol production from syngas is promising but limited by microbial energy conservation and gas–liquid mass transfer. This review integrates advances in cultivation control and bioreactor engineering with next‐generation biological tools including metabolic rewiring, co‐cultivation and chain elongation, and electro‐fermentation to enable carbon ...

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.

A Critical Review on Green Conversion Techniques of Biomass Waste to Value‐Added Bioproducts: Advances, Challenges, and Future Technological Strategies

GCB Bioenergy, Volume 18, Issue 5, May 2026.
This study highlights developments in cost‐effective fractionation techniques to ensure the sustainability and industrial applicability of biomass. ABSTRACT Given the depletion of fossil fuels and global concerns about environmental protection, lignocellulosic biomass is an excellent alternative candidate due to its unique combination of ...

Performance Evaluation of a Full‐Scale Anaerobic Internal Circulation Reactor Treating Calcium Rich Dairy Industry Wastewater

Water and Environment Journal, Volume 40, Issue 2, Page 290-300, May 2026.
This study investigates the impact of calcium on the performance of a large‐scale internal circulation (IC) reactor treating calcium‐rich dairy wastewater. Excessive calcium concentrations (400‐600 mg L−1) resulted in calcification of the anaerobic sludge, reactor walls, and pipes, suggesting a 17% and 25% reduction in biogas and methane production ...
