What Is Biomethane? How It’s Made, Used and Why It’s Renewable
Biomethane is purified biogas that can replace fossil natural gas in compatible pipelines, boilers, industrial processes and vehicles. Discover how it is made, why its environmental performance depends on feedstocks and methane control, and where this renewable gas is most useful.
Biogas Additives for Anaerobic Digestion: When They Work and Why
Biogas additives can improve anaerobic digester performance, but only when the additive addresses a genuine limitation in the process. Trace elements, enzymes, iron compounds, buffering agents, antifoams and other products all have legitimate applications, but there is no universal additive that will automatically increase methane yield in every digester. No reputable additive supplier will ever […]
Biogas Digester: How It Works, Types and Uses
A biogas digester is a sealed reactor in which microorganisms break down organic material without oxygen. This process, called anaerobic digestion, produces biogas and a remaining material called digestate. “Methane digester” is another name people use for a biogas-producing anaerobic digester: methane is the energy-rich component of the gas, rather than a different digestion process. […]
Methane Facts and Why It’s a Greenhouse Gas Much Worse than Carbon Dioxide
Climate Clarity: What You Need to Know About Methane and Global Warming Methane is the second-largest driver of global warming after CO2, responsible for roughly 30% of the temperature rise since the Industrial Revolution. Molecule for molecule, methane traps heat 86 times more powerfully than carbon dioxide over a 20-year period — making every emission […]
Bringing Your Sustainable Business Plans to Life the Right Way
Sustainability has always been a huge driver for the anaerobic digestion community, and now it is becoming a practical business priority across all of agriculture and industry. From renewable energy generation to improved waste management, businesses are looking for ways to reduce their environmental impact while maintaining productivity and controlling costs. Having an ambitious sustainability […]
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 […]
