New technology enables biogas plant optimization
Governments around the world are seeking to lower greenhouse gas (GHG) emissions in the fight against climate change, to reduce waste to landfill, and to increase their utilisation of renewable energy in compliance with international agreements. Consequently, in many countries, subsidies have been made available to encourage the growth of the biogas sector. According to the International ...

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 ...

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 ...

Recovering biomethane and nutrients from anaerobic digestion of water hyacinth (Eichhornia crassipes) and its co-digestion with fruit and vegetable waste
The potential to recover bioenergy from anaerobic digestion of water hyacinth (WH) and from its co-digestion with fruit and vegetable waste (FVW) was investigated. Initially, biogas and methane production were studied using the biochemical methane potential (BMP) test at 2 g volatile solids (VS) L−1 of substrate concentration, both in the digestion of WH alone and in its co-digestion with FVW ...

The promotion and development of renewable energy technologies: current status and pattern of use in Nepal
This paper presents the current status and pattern of use of Renewable Energy Technologies (RETs) in Nepal. The importance of the renewable energy development paradigm is considered in the overall context of national development by supplying the energy requirements of rural areas by the use of available biomass resources whilst also protecting the environment. The RETs popular in the rural energy ...

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 ...

Aerobic thermophilic bacteria enhance biogas production
The enhancing effect of aerobic thermophilic (AT) bacteria on the production of biogas from anaerobically digested sewage sludge (methanogenic sludge) was investigated. Sewage sludge (5%, w/w) was incubated at 65°C with shaking for a few months to prepare the AT seed sludge. AT sludge was prepared by incubation of the AT seed sludge (5%, v/v) and sewage sludge (5%, w/w) at 65°C with shaking. The ...

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 ...

Anaerobic co-digestion of surplus yeast and wastewater to increase energy recovery in breweries
Surplus yeast is a residue produced during brewery process, which presents high contents of organic matter. Biogas production from yeast could significantly contribute to bioenergy production in breweries, via biogas generation. Co-digestion of surplus yeast and brewery wastewater in a single treatment step would simplify the technical and economical requirements for the transformation of both ...
