Seaweed Anaerobic Digestion: Can Beach Strandings Be Turned into Biogas?
Large seaweed strandings can create serious odour and health problems as the biomass decomposes. Could collecting the seaweed and using anaerobic digestion turn a coastal nuisance into renewable biogas? This article examines the opportunity, including ensiling for year-round storage, salinity inhibition, hydrogen sulphide, silage liquor and the essential safety precautions needed when handling decomposing seaweed.
Biogas Plant Project and Setup Cost: A Practical Guide to CapEx, Equipment and Development
What does a biogas plant really cost to set up? This practical guide explains CapEx, equipment, development costs and budget exclusions, with farm CHP, food-waste and biomethane examples. It also covers UK connections, contingency and the cash needed to reach stable operation.
AD Pumps for Anaerobic Digestion: Landia Pumps, Mixers and Biogas Applications
What exactly is an AD pump, and why are ordinary pumping duties so difficult in an anaerobic digestion plant? Fibres, grit, viscous biomass and high solids can expose unsuitable equipment very quickly. This newly expanded guide looks at AD pumps, feed pumps, digestate pumps and chopper pumps, using Landia equipment and real biogas applications as examples.
The Importance of Biogas: 10 Benefits for Energy, Cities, Farms and Homes
For many years, the importance of biogas was discussed mainly in terms of renewable energy, waste recycling and reducing greenhouse gas emissions. Those benefits remain important. But events in 2026 have brought another advantage sharply into focus: energy security and resilience. When internationally traded oil and gas supplies are disrupted, the consequences can travel thousands […]
Anaerobic Digestion Planning Permission: Are England’s New AD Plants Hitting a Planning Wall?
Three major rural AD plants were refused planning permission in England in just 59 days in summer 2026. Is this simply NIMBY opposition, or is obtaining permission for new anaerobic digestion and biomethane plants genuinely becoming harder?
Fugitive Emissions Testing: The Complete Guide for the Biogas Industry UK
Fugitive Emissions Testing: A Comprehensive LDAR Handbook for the UK Biogas Sector Did you know? Up to 3% of valuable biogas can quietly dissipate every year from a typical UK plant as fugitive emissions—enough to damage your bottom line and the environment. This is more than just an operational hiccup; it’s a hidden threat to […]
Anaerobic Digestion Courses: Academic, Industry and Expert-Led Online Training
Anaerobic digestion courses now range from free introductory online learning to specialist operator training, professional CPD, university-level study and formal operator certification. That is good news if you want to enter the biogas industry or deepen your existing knowledge. It also creates a problem: an AD plant operator, an engineer, a project developer and somebody […]
AD Certification Scheme: ADCS UK Requirements, Audits and International Expansion
The AD Certification Scheme provides an independent assessment of the safety, environmental and operational performance of anaerobic digestion plants. For operators, ADCS certification offers more than a badge for the company website. The audit can expose weaknesses in management systems, staff competence, maintenance, process monitoring, environmental controls and day-to-day operating practices before those weaknesses contribute […]
Digestate Fertilizer: What It Is and How to Use It in Agriculture
Digestate fertilizer is one of the two principal outputs from an anaerobic digestion plant. Biogas receives most of the attention because it produces renewable energy, but the material remaining after digestion contains valuable nitrogen, phosphate, potash, sulphur and organic matter. Used correctly, digestate can replace part of a farm’s purchased fertilizer requirement and return nutrients […]
I Wrote an 65 Page UK Anaerobic Digestion Market Report. In 6 Months Only 1 Sold.
I have a small confession to make. Earlier this summer, I spent the best part of three working days researching and writing a new UK Anaerobic Digestion Market Report 2026. It runs to 65 pages. It is the first full UK AD market report I have produced since 2017, and the industry I found when […]
Anaerobic Digester Mixing Systems: Lowest Cost, Reliability and Better Performance
Anaerobic digester mixing systems are easy to underestimate. A mixer may represent only one part of an anaerobic digestion plant, but poor mixing can affect effective digester volume, energy consumption, maintenance costs, biological performance and ultimately the reliability of the whole biogas process. This becomes particularly important when digesters process agricultural feedstocks such as cattle […]
Renewable Heat Incentive (RHI): What It Was, Why It Closed and Lessons for Biogas CHP
The Renewable Heat Incentive (RHI) was a UK government support scheme designed to encourage the production and use of renewable heat. For the anaerobic digestion and biogas sector, it became particularly important because it could support the use of biogas for heat and, under qualifying arrangements, the useful heat recovered from combined heat and power […]
