Biogas Information UK: Reliable Anaerobic Digestion Resources, Data and Guidance
Where should you go for reliable biogas information in 2026? This newly expanded guide brings together trusted UK sources for anaerobic digestion, regulation, plant data and technical guidance, while also answering the most-searched questions about how biogas is produced, its uses, examples and advantages.
High Solids Anaerobic Digestion: Processes, Feedstocks, Benefits and Limitations
High solids anaerobic digestion (HSAD) is the biological digestion of organic materials at substantially higher total-solids concentrations than conventional wet anaerobic digestion. It is particularly relevant to feedstocks such as source-separated organic waste, the organic fraction of municipal solid waste (OFMSW), crop residues, manures and other materials that would otherwise require large quantities of dilution […]
Anaerobic Digestion Technology: Digester Types, Processes and Modern AD Systems
Anaerobic digestion technology is far more than a digester tank. This guide compares CSTR, plug-flow, high-solids, two-stage, UASB and other AD systems, plus modern process control, biogas upgrading and digestate technology.
Biogas Storage: Gas Holders, Tanks, Bags and Storage Methods
Biogas storage provides a buffer between continuous gas production and the sometimes variable demand for that gas. Anaerobic digesters normally produce biogas around the clock, while CHP engines, boilers, upgrading plants and other gas users may shut down, operate at reduced load or experience periods of higher and lower demand. For that reason, almost every […]
Biogas Upgrading Technologies: How Biogas Is Upgraded to Biomethane
Which biogas upgrading technology is best for producing biomethane? This guide compares membrane separation, water scrubbing, PSA, amine systems and other technologies, including methane recovery, pretreatment, methane slip, cost drivers and gas-grid injection.
Biogas pH Control Equipment: Monitoring, Alkalinity and Dosing for Anaerobic Digesters
Biogas pH control involves much more than measuring pH and adding alkali. Learn how digester pH probes, alkalinity, VFAs, FOS/TAC and dosing equipment work together to identify and prevent anaerobic digestion process instability
Anaerobic Digestion Plant Design: A Practical Guide to Digester Sizing, Layout and Engineering
Successful anaerobic digestion plant design begins with the feedstock, not with a digester tank selected from a catalogue. The quantity, composition and variability of the material entering the plant determine the digestion process, reactor volume, feeding system, mixing duty, heating demand, biogas production, digestate output and much of the civil engineering. An AD plant must […]
Biogas Generator Manufacturers: How to Compare Gas Engine and CHP Suppliers
Choosing between biogas generator manufacturers is not simply a matter of comparing the number of kilowatts printed on competing quotations. A generator set that looks excellent on a datasheet can become expensive very quickly if it is poorly matched to the available biogas, difficult to service locally, sensitive to contaminants or routinely operated well below […]
Biogas Companies Europe: Turnkey AD Plant Contractors and Manufacturers
This updated list of biogas companies in Europe focuses on businesses that can design, supply, construct or commission a complete anaerobic digestion plant. It includes established EPC contractors, turnkey biogas plant manufacturers and specialist system providers serving agricultural, food-waste, municipal-organic-waste and industrial projects. The expression complete biogas plant manufacturer can be confusing. It does not […]
Anaerobic Co-Digestion: Feedstock Combinations and Why They Work
Anaerobic co-digestion is the simultaneous digestion of two or more different biodegradable feedstocks in the same anaerobic digester. Typical combinations include food waste with manure or slurry, food waste with sewage sludge, and agricultural residues with animal manures. The idea sounds simple: mix organic materials together and produce biogas. But successful co-digestion is much more […]
How to Make Biogas: From Organic Waste to Renewable Gas
Biogas is made when microorganisms break down biodegradable organic material in the absence of oxygen. The controlled process is called anaerobic digestion, and it can convert food waste, animal manure, sewage sludge, crop residues and many other organic materials into a useful renewable gas. The principle sounds simple: place biodegradable material in an airtight digester […]
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.
