Reasons for Biogas Optimism Despite Global Challenges

Reasons for Biogas Optimism Despite Global Challenges

The first few months of 2025 have been among the most economically turbulent in recent history, but despite this there are still signs anaerobic digestion (AD) will continue to play a key role in boosting energy security, tackling climate change, and managing organic wastes. The global biogas market was estimated to be worth USD 65.53 billion in 2024 and is projected to expand 4.2% per year ...

Effect of solid-state NaOH pretreatment on methane production from thermophilic semi-dry anaerobic digestion of rose stalk

Effect of solid-state NaOH pretreatment on methane production from thermophilic semi-dry anaerobic digestion of rose stalk

The effects of solid-state NaOH pretreatment on the efficiency of methane production from semi-dry anaerobic digestion of rose (Rosa rugosa) stalk were investigated at various NaOH loadings (0, 1, 2, and 4% (w/w)). Methane production, process stability and energy balance were analyzed. Results showed that solid-state NaOH pretreatment significantly improved biogas and methane yields of 30-day ...

Semi-continuous mesophilic anaerobic co-digestion of thermally pretreated scum

Semi-continuous mesophilic anaerobic co-digestion of thermally pretreated scum

The objective of this study is to investigate the mesophilic, anaerobic, co-digestion of scum with thickened waste activated sludge (TWAS) and primary sludge (PS). Observations of the reactor waste show that higher pretreatment temperatures assist in scum integration and appear to limit coagulation and separation effects associated with digesting fats, oils and greases. The 0.40 kg VS/m3 · d ...

Recovering biomethane and nutrients from anaerobic digestion of water hyacinth (Eichhornia crassipes) and its co-digestion with fruit and vegetable waste

Recovering biomethane and nutrients from anaerobic digestion of water hyacinth (Eichhornia crassipes) and its co-digestion with fruit and vegetable waste

Subsequently, the biogas production was optimized in terms of total solids (TS) concentration, testing 4 and 6% of TS. The BMP test showed a biogas yield of 0.114 m3 biogas kg−1 VSadded for WH alone. On the other hand, the biogas potential from the WH-FVW co-digestion was 0.141 m3 biogas kg−1 ...

Evaluation of thermal steam-explosion key operation factors to optimize biogas production from biological sludge

Evaluation of thermal steam-explosion key operation factors to optimize biogas production from biological sludge

Thermal steam-explosion is the most extended hydrolysis pretreatment to enhance anaerobic digestion of sludge. Thermal hydrolysis key parameters are temperature (T) and time (t), and the generally accepted values reported from full-scale information are: 150–230 °C and 20–60 min. This study assesses the influence of different temperature–time–flash combinations (110–180 °C, 5–60 min, 1–3 ...

Livelihood–based environmental education in the endogenous development of Nepal: survey based on biogas technology usage

Livelihood–based environmental education in the endogenous development of Nepal: survey based on biogas technology usage

Discussions of endogenous development in developing countries and environmental education focus on livelihood aspects as a decisive factor. However, current environmental education mainly focuses on the natural environment and lacks particular focus on livelihood aspects. This paper incorporates livelihood–based environmental education and investigates endogenous development in the Chitwan ...

Anaerobic co-digestion of sewage sludge and primary clarifier skimmings for increased biogas production

Anaerobic co-digestion of sewage sludge and primary clarifier skimmings for increased biogas production

The objective of the study was to identify the impact of co-digesting clarifier skimmings on the overall methane generation from the treatment plant and additional energy value of the increased methane production. Biogas production from co-digesting clarifier skimmings and sewage sludge in pilot-scale fed-batch mesophilic anaerobic digesters has been evaluated. The digester was fed with ...

Increased biogas production in a wastewater treatment plant by anaerobic co-digestion of fruit and vegetable waste and sewer sludge – A full scale study

Increased biogas production in a wastewater treatment plant by anaerobic co-digestion of fruit and vegetable waste and sewer sludge – A full scale study

Anaerobic digestion is a well established technology for the reduction of organic matter and stabilization of wastewater. Biogas, a mixture of methane and carbon dioxide, is produced as a useful by-product of the process. Current solid waste management at the city of Prince George is focused on disposal of waste and not on energy recovery. Co-digestion of fresh fruit and vegetable waste with ...
