Biomethane production from anaerobic co-digestion at wastewater treatment plants: A critical review on development and innovations in biogas upgrading techniques.

Science of the Total Environment, 2020
Anaerobic co-digestion (AcoD) can utilise spare digestion capacity at existing wastewater treatment plants (WWTP) to generate surplus biogas beyond the plant's internal energy requirement.

Biogas policies and production development in Europe: a comparative analysis of eight countries

Biofuels, 2022
This paper compares and analyzes the relations between the biogas development and the national policy frameworks for biogas solutions in eight European countries. The policy frameworks are compared using a biogas policy model, comprising five dimensions:

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

American Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Strategic management of nitrogen within an organic cropping system using digestate from biogas production of recirculated crop residues [PDF]

, 2013
This project investigates strategic management of nitrogen by integrating crop residue management with biogas production. The approach offers potential for diversified farmer income, as food crops, feedstock for biogas and digestate for nutrient cycling ...

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Combined effect of increasing the post‐reformer temperature and adding red mud as a secondary catalyst in the thermocatalytic reforming of digestate

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension

Dual valorization of bamboo waste via superheated steam torrefaction: Efficient bioenergy production and pollutant adsorption

Cleaner Engineering and Technology
Bamboo waste is an abundant renewable biomass, yet its direct use as fuel is limited by high moisture and low calorific value. Developing efficient valorization strategies is therefore essential for sustainable energy and environmental applications. This
