ClearEfficient Biorefinery Based on Designed Lignocellulosic Substrate for Lactic Acid Production
Researchers developed a simultaneous saccharification and fermentation (SSF) process using Celluclast 1.5L enzyme to produce L-lactic acid from brewer's spent grain, achieving 53.1 g/L optically pure product with a volumetric productivity of 3.65 g/L/h without nutrient supplementation. The approach overcomes glucose-induced carbon catabolite repression by co-utilizing pentose and hexose sugars from lignocellulosic biomass.

Unveiling the mechanisms of medium-chain fatty acid production from waste activated sludge alkaline fermentation liquor through physiological, thermodynamic and metagenomic investigations
Researchers investigated converting waste activated sludge fermentation liquor into medium-chain fatty acids (valuable biochemicals) through chain elongation with ethanol as an electron donor, finding optimal selectivity at a 1:1 electron donor-to-acceptor ratio, and identifying Clostridium species as the key microbial drivers using metagenomic analysis — demonstrating a promising pathway for simultaneously treating sewage sludge and producing bio-based chemicals.
Microbial valorization of underutilized and nonconventional waste streams
This review examines how microorganisms can be used to convert nonconventional waste streams, including food processing effluents and industrial wastewater, into valuable fuels and biochemicals through fermentation. The study discusses the challenges associated with waste stream impurities, toxicity, and low productivity while highlighting the growing potential of microbial valorization approaches.

This review discusses the role of lactic acid bacteria in solid waste management, including their use as probiotics in food systems and their potential to produce polylactic acid (PLA), a biodegradable plastic. Using microbes to produce bioplastics that break down naturally could help reduce persistent microplastic pollution.
Conversion of lignocellulose residue obtained from biorefinery stream to electricity by microbial fuel cell
This review explores using microbial fuel cells (MFCs) to generate electricity from the organic waste left over after lignocellulose biorefinery processes. While focused on bioenergy, the circular economy approach discussed is relevant to reducing industrial waste streams that could otherwise contribute to environmental pollution.
Nitro-oxidation process for sustainable production of carboxylated lignin-containing cellulose nanofibers from sugarcane bagasse
Researchers used a nitric acid oxidation process to convert raw sugarcane agricultural waste directly into biodegradable cellulose nanofibers without pre-treatment, while simultaneously recovering the liquid byproducts as biofertilizer, offering a sustainable pathway to replace some synthetic plastics and reduce microplastic pollution.

The Potential of Ozonation to Reduce Impact of Waste Sludge-Entrapped Microplastics to Biogas Production
Wastewater treatment plants concentrate microplastics from sewage into the resulting sludge, and this study tested whether ozonation could reduce the harm those microplastics cause during anaerobic digestion used to produce biogas. The findings showed that PET and polypropylene microplastics alter methane yields from sludge digestion in concentration-dependent ways, and that ozone pretreatment partially mitigates the inhibition caused by polypropylene — though the interactions are complex and require further optimization before widespread use.
