Biogas in China: From Household Digesters to Industrial Biomethane
Biogas in China is changing. Household digesters helped establish the country’s long association with anaerobic digestion, but they no longer tell the whole story. Larger plants, professional operation and the production of upgraded biomethane are increasingly important. Understanding that transition means separating China’s historical achievements from its operating plants today, and distinguishing future ambitions from […]
A Comprehensive Review of the Top 7 Fixed Biogas Analysers: Your Definitive Buyer’s Guide for 2026
A 2026 buyer’s guide to the top 7 fixed biogas analysers built for continuous, SCADA-wired monitoring on biogas plants. Covers NDIR, electrochemical, paramagnetic and laser-based (TDLAS) technology, real manufacturers and models (Siemens, SICK, QED/LANDTEC, Awite, Union Instruments, BlueSens, DURAG), SCADA protocols, ATEX certification, installation and maintenance best practice. Portable handheld analysers are covered in a separate article.
Food Waste Disposal Costs: Anaerobic Digestion vs Composting Which is Cheaper
With weekly household food waste collections mandatory in England since 31 March 2026 under Simpler Recycling, choosing between anaerobic digestion and commercial composting can swing hundreds of thousands of pounds a year for a single council. We compare WRAP’s Gate Fees Report 2025/26 with letsrecycle.com’s 2026 organics prices to show which route is cheaper, and why the gap is narrowing.
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.
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 […]
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 […]
