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 ...
Biogas analyzers play a crucial role in this, as they enable us to monitor and optimize biogas production in real-time. ...
In the future, a BioBANG technology will support the substrate digestion of the Blum biogas plant in the Vulkaneifel New installation of BioBANG in Renè Blum’s biogas plant in the Vulkaneifel district of the Rhineland. BioBANG, installed in recirculation on the main digester, ensures greater digestion of the most difficult substrates. This not only increases the biogas production, ...
The Vaisala stand, 016 in hall D6, at the Ecomondo Green Technology Expo in Rimini, Italy, 5-8 November 2019, will feature Vaisala’s new Ex certified in-line multigas measurement instrument, the MGP261. With this technology, biogas plant operators will, for the first time, be able to optimize the production of high quality biogas in ...

Doosan actively invests in its waste and renewable energy related research and development activities to create and launch needs-driven technologies that will introduce innovative solutions to the worldwide waste and renewable ...
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 ...
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 ...
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 ...
Allens Farm anaerobic digestion (AD) facility is located within the beautiful countryside of Colchester, which is said to be the oldest recorded town in Great Britain. The farm is run by three partners – David Hunter, Charlie Lochore and Will Lochore, who felt an anaerobic digestion (AD) plant would make an excellent addition to their farming business. Austrian company Thoeni were ...
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 ...
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 ...
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 ...
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 ...
The microaerobic removal of H2S was studied to determine the treatment capacity at low and high H2S concentrations in the biogas (0.33 and 3.38% v/v) and to determine the optimal O2 rate that achieved a concentration of H2S of 150 mg/Nm3 or lower. ...
With a strong industrial base and successful commercialisation of technologies in renewable energy, India is in a position today to offer state-of-the-art technology to other developing countries and is poised to play a leading role in the global movement towards sustainable energy development. India has a separate ministry to promote renewable energy sources, which has been named Ministry of ...
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 ...
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 ...
