Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1656-1676, April 2026.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Thermodynamics of anaerobic digestion: Mechanism of suppression on biogas production during acidogenesis [PDF]

open access: yes, 2019
Anaerobic digestion process consists of several stages in which different type of microorganisms are involved. The current study reviews some possible reactions occurred in anaerobic digestion particularly in acidogenesis stage.

Effect of Stirring on Organic Matter Conversion in Horizontal Biodigesters

open access: yesWater Environment Research, Volume 98, Issue 4, April 2026.
The mechanical stirring effectively mitigates sludge accumulation without compromising overall treatment performance or biogas generation, promoting a reduced buildup of solids within the reactor. ABSTRACT This study investigated the effect of localized mechanical stirring on the performance and organic matter conversion pathways in two bench‐scale ...

Robust Performance of Sub‐Thermophilic Anaerobic Digestion Enabled by Microbial Functional Redundancy

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
We tested whether anaerobic digesters could operate at lower temperatures without losing methane production. Pilot‐scale reactors were run at 48°C or 55°C. Methane yields and gas quality were similar. Lower temperatures reduced volatile fatty acids and supported more diverse microbial communities.

Characterisation of high-rate acidogenesis processes using a titration and off-gas analysis sensor

open access: yes, 2005
The characteristics of the glucose degradation by acidogenesis processes were investigated both in a long-term operating laboratory-scale continuously stirred tank reactor and in short-term experiments utilising a titration and off-gas analysis (TOGA ...

Influence of hydraulic retention time on the psychrophilic hydrolysis/acidogenesis of proteins

open access: yesWater Science and Technology, 2016
The influence of the hydraulic retention time (HRT) on the anaerobic hydrolysis of complex substrates has been studied under psychrophilic conditions. For this purpose, a continuous stirred tank reactor was operated at 15 °C and neutral pH and gelatin was considered as a model protein. Three HRTs have been tested: 12, 21 and 36 h.
