The Role of Laboratory Models in Sustainable Biotechnology Research
Sustainability has become an important consideration across biotechnology, including the anaerobic digestion industry, influencing everything from laboratory practices to the development of new materials, medicines, and manufacturing processes. Laboratory models play a central role in this work because they allow researchers to investigate biological mechanisms under controlled conditions before moving towards more resource-intensive stages of development. By choosing appropriate models […]
Biogas Production Process Steps: From Feedstock to Usable Biogas
The biogas production process converts biodegradable organic material into a methane-rich gas that can be used as a renewable source of energy. But there is an important distinction that is often missed when the process is explained. The four stages commonly described as the “4 stages of biogas production” — hydrolysis, acidogenesis, acetogenesis and methanogenesis […]
Small-Scale Anaerobic Digestion for Farms, Businesses and Communities
Small-scale anaerobic digestion can provide a practical way for farms, food businesses, institutions and communities to treat organic residues while producing biogas and digestate. But reducing the size of an anaerobic digestion plant does not automatically make the technology simple or inexpensive. A small digester still needs a reliable feedstock, biological process control, pumps and […]
Uses and Applications of Biogas: 10 Ways Biogas Is Used
What are the main uses of biogas? The answer ranges from generating electricity and heat to replacing natural gas in pipelines, fuelling vehicles and providing cooking fuel at household scale. Biogas is unusually versatile because its principal energy-carrying component is methane. Raw biogas can be burned directly in suitable equipment after the gas treatment required […]
UK Biogas Funding: How RO, FITs, RHI and GGSS Shaped Anaerobic Digestion
UK biogas funding has played a major part in shaping the anaerobic digestion industry we see today. Over the past two decades, government support has encouraged renewable electricity from biogas, rewarded useful renewable heat and, more recently, shifted strongly towards producing biomethane for injection into the gas grid. That history matters because government incentives did […]
Biogas Engines and Generators: How They Turn Biogas into Electricity
We have defined what we mean by a biogas engine and how such engines are used as a biogas generator, including discussing what cogeneration means in terms of secondary heat ultilisation and CHP
Biogas Heating Systems: Boilers, Direct Heat and When They Beat CHP
A biogas heating system can be one of the simplest and most efficient ways to use the gas produced by an anaerobic digestion plant. Instead of converting the biogas into electricity first, the gas is burned in a suitable boiler or process heater and its energy is used directly as heat. That option is sometimes […]
Biogas CHP Systems: Benefits, Efficiency, Costs and Design
Biogas CHP systems transform waste into power, achieving efficiencies over 80%. Ideal for on-site energy, they lower bills and carbon emissions. Agricultural producers, wastewater plants, and landfill operators benefit, despite the high upfront capital costs, by turning waste into reliable energy sources for sustainable operations…
Biogas Utilisation: CHP, Biomethane, Heat and the Best Uses for Biogas
Biogas utilization thrives on combining heat and power units for maximum efficiency. With energy efficiencies reaching up to 90%, CHP systems are a game-changer in waste management and renewable energy production, offering energy independence and diverse revenue streams for agricultural and municipal operations alike…
Anaerobic Digestion Heat Exchangers: Types, Uses, Fouling and Heat Recovery
Anaerobic digestion heat exchangers perform one of the less glamorous but most important jobs on a biogas plant: moving heat from where it is available to where the process actually needs it. They can heat incoming feedstock, maintain digester temperature, recover heat from hot digestate, transfer heat from CHP engines, provide energy for pasteurisation and, […]
Biogas CHP Design: 7 Factors for Selecting and Sizing a CHP System
Biogas CHP design involves much more than selecting a gas engine with an electrical output that appears to match the expected biogas production from an anaerobic digestion plant. A successful combined heat and power (CHP) installation must match the quantity and quality of the available biogas, the site’s electrical demand, the genuinely useful heat demand, […]
Do Home Biogas Digesters Really Work? Costs, Gas Output, Safety and Common Myths
Do home biogas digesters work? Yes. A correctly sized and well-operated home biogas digester can turn food scraps or animal manure into useful cooking gas and nutrient-containing digestate. However, these systems do not produce unlimited free energy; they are not equally effective in every climate, and they require appropriate installation, feeding and maintenance. If you […]
