Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization

open access: yesChemBioEng Reviews, Volume 13, Issue 2, April 2026.
The review article begins with an introduction that covers the overview, food waste (FW) classification, and the steps involved in producing biogas through anaerobic digestion (AD). Following that, it describes the process for producing biogas, including single‐, two‐, and multistage systems, mesophilic and thermophilic digestion, and wet and dry ...

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 ...

Einfluss der Düngung mit Gärrückständen aus der Biogaserzeugung auf den Ertrag von Silomais und auf die bodenmikrobielle Aktivität [PDF]

open access: yes, 2007
Organic manuring with slurry from biogas plants may contribute to plant nutrition and maintenance of soil fertility in organic farming. However, the chemical properties of biogas slurry depend markedly on substrate input and process technology.

Biogas recirculation technology: Effect on biogas purification, slurry characteristics, microbial activity and energy consumption

open access: yesEnvironmental Technology & Innovation, 2020
Abstract In the present study, effect of biogas recirculation on slurry characterization, microbial activity and biogas purification were studied. Two digester units, one for control treatment and another equipped with a gas compression system for recirculation treatment, were designed and constructed.

Full Manure Recycling Risks an 18% Rise in China's Cropland N2O Emissions Without Improved Management

open access: yesGlobal Change Biology, Volume 32, Issue 4, April 2026.
By 2050, merely pursuing 100% manure recycling without improving manure‐N use efficiency could lead to an 18% increase in N2O‐N losses compared with 2019. This challenges China's current policy focus solely on manure recycling quantity, as reflected in the “14th Five‐Year Plan for National Agricultural Green Development” (2021–2025).

Crystal Engineering of Reticular Materials for Gas‐ and Liquid‐Phase Hydrocarbon Separation

open access: yesAdvanced Materials, Volume 38, Issue 16, 17 March 2026.
Crystal engineering enables systematic study of structure/function relationships as exemplified by pore engineering of reticular sorbents, including porous coordination networks and covalent organic frameworks. This review assesses such studies applied across the full scope of industrially relevant hydrocarbon separations to provide insight into how ...

Co-digestion of Food Waste and Human Excreta for Biogas Production [PDF]

open access: yes, 2013
The ever increasing cost of fossil fuels and its attendant pollution menace has provided the pedigree to consider alternative sources of energy. An investigation was launched into the design and construction of an Anaerobic Digester system from locally

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.

Unravelling the active microbial community in a thermophilic anaerobic digester-microbial electrolysis cell coupled system under different conditions [PDF]

open access: yes, 2017
Thermophilic anaerobic digestion (AD) of pig slurry coupled to a microbial electrolysis cell (MEC) with a recirculation loop was studied at lab-scale as a strategy to increase AD stability when submitted to organic and nitrogen overloads.
