Sustainable and cost‐effective process design for energy‐self‐sufficient ethyl lactate production from sugar mill feedstocks: a techno‐economic approach

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 487-507, March/April 2026.
Abstract Bio‐based ethyl lactate (EL) can replace several fossil‐derived products owing to its low toxicity, high solvent functionality, and environmental advantages. This study assesses the techno‐economic viability and greenhouse gas (GHG) reduction potential of producing EL from sugarcane A‐molasses and lignocelluloses in an energy self‐sufficient ...

Prediction of slurry operating temperature and biogas production rate using ambient temperature forecast as input parameter for underground brick-built biogas digesters

Cogent Engineering, 2022
The operational temperature of the biogas digester is the most critical parameter for optimum biogas production. Most household digesters are operated at ambient temperatures throughout the year.

Valorization of paper sludge for bioethanol and biogas production

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 817-825, March/April 2026.
Abstract This study evaluated the physicochemical properties and bioenergy potential of three distinct paper sludges: virgin pulp sludge (VP‐PS), corrugated cardboard sludge (CR‐PS), and tissue and printing paper sludge (TPR‐PS). From the experimental runs, VP‐PS exhibited the highest ethanol yield (46.8 ± 3.7 g L−1, 87.4% conversion), which can be ...

Environmental risks in swine biogas slurry-irrigated soils: A comprehensive analysis of antibiotic residues, resistome, and bacterial pathogens

Environment International
Simple anaerobic digestion is insufficient to completely remove residual parent antibiotics and antibiotic resistance genes (ARGs) from animal manure. ARG prevalence in swine biogas slurry-irrigated soils threatens human health.

Problems with Biogas Implementation in Developing Countries from the Perspective of Labor Requirements

Energies, 2016
Most households in rural developing countries depend on firewood from public forests or agricultural bio-wastes for cooking. Public forests, though, are declining due to an increasing population and inefficient use of wood.

Combined Effect of Cetane Improver, Aluminum Oxide Nanoparticles, and Waste Cooking Oil Biodiesel Blend on a Dual Fuel Combustion Engine Run With Biogas Originated From Food Waste

Energy Science &Engineering, Volume 14, Issue 3, Page 1372-1386, March 2026.
Sugarcane juice is clarified and fermented with yeast to produce ethanol and CO₂. The broth is refined through distillation and molecular sieves, yielding fuel‐grade ethanol stored for transport. Bagasse, vinasse, and residues are recycled as valuable by‐products, enabling a sustainable bioethanol production pathway ABSTRACT This study investigates the
