Digestate from Anaerobic Digestion: A Valuable Nutrient-rich Liquid for Sustainable Agriculture
Using digestate from Anaerobic Digestion provides a valuable plant fertiliser. In fact, unlocking the potential of digestate is vital for the sustainability of the agriculture sector. There is nothing else quite as good when you take a holistic view of its many benefits. Digestate is a valuable nutrient-rich liquid produced from the process of anaerobic […]

On This Page Clean Energy Provides Grant Application Support for 168 Near Zero RNG Trucks Clean Energy to Supply Dallas Fort Worth International Airport with Renewable Natural Gas; DFW Becomes First Airport Outside California to Use Redeem™ RNG Truck Drivers Like Helping the Environment with Near-Zero RNG Trucks Truck Drivers Like the Performance of Near-Zero […]
Pilot-plant Biogas Reactor – How to Do a Pilot Trial Step by Step
How to build and run a small lab scale Pilot-plant Biogas Reactor to carry out the anaerobic digestion of plant biomass (waste organic materials you have available to you for free or at minimal cost) with an A.D. pilot plant experiment, sometimes called a Lab Trial. This is an experimental pilot plant laboratory method to […]
Green Biogas – UK Green Investment Bank Backing Is Proof
We have said many times that the anaerobic digestion process makes green biogas profitable with a good ROI, but where is the proof of that? Back in December 2012 when we first posted this article, we based our case on a “Utility Week” article here which announced that Anaerobic digestion and energy efficiency had won the […]
UK Anaerobic Digestion Plants Exceed 100 And Hit Trouble: Looking Back
In this article, we will look back at our March 2013 article when UK Anaerobic Digestion Plants exceeded 100 and were receiving damaging media attention due to novice operators causing some high-profile environmental problems. So, we reported that they were “hitting trouble”. The fact is that now (in 2023), with the benefit of hindsight, we […]
Join the Fight Against Climate Change with Rapid Biogas Deployment
Are you looking for a solution to the climate crisis? Look no further than anaerobic digestion (AD) and join the fight against climate change with rapid biogas plant deployment. The latest IPCC report has called for urgent action in adopting low-carbon technologies to help meet global warming targets, and AD has emerged as one of […]
Microplastic Contamination in Compost – Composted Green Waste vs Digestate
Microplastic contamination in compost is a problem now, and in geological timescales, all plastic in soils will be washed into the oceans, leading to yet more microplastics in the oceans. But which source of compost is worse for containing microplastics? Composted green waste or the digestate from anaerobic digestion? In this article, we compare both. […]
4 Anaerobic Digestion Regulations – UK Environmental Protection, Animal By-products, Duty of Care, Health and Safety
Anaerobic Digestion Regulations surprisingly, don’t exist in the UK. At least not all neatly bundled into a single government act or rule book. Instead, AD Plant operators must comply with a range of statutory requirements (“Laws” to you and me). The four main UK Anaerobic Digestion Regulations which must be tackled to ensure compliance once […]
Federal Renewable Fuel Standard Changes: Financial Windfall for Anaerobic Digesters and Landfills?
Depending on how the final details shake out during 2023, proposed changes to the federal Renewable Fuel Standard programme could be a financial boon for operators generating energy from anaerobic digesters and landfills. Introduction The proposed changes to the federal Renewable Fuel Standard (RFS) program in the US could be a financial opportunity for operators […]
ROCs Explained and Why Scheme Closure in 2017 Shocked the UK AD Industry
ROCs Explained! In this article, we explain ROCs (Renewables Obligation Certificates). And, why the 2017 closure of the scheme to new generator capacity and businesses for Anaerobic Digestion was a big shock to the UK AD industry at the time. To many people, it still seems like a mistake and a missed opportunity for UK […]
Anaerobic Digestion Basics and 5 Tips on How AD Works
We bring you the Anaerobic Digestion Basics (AD) and if you scroll down, 5 tips on how AD Works. AD is in-truth an unhelpful acronym for the basic age-old natural process that produces renewable energy as heat and biogas, and at the same time makes a natural crop fertilizer. That, in a nutshell, is basic […]
Anaerobic Digester Mixing Systems With Lowest Cost of Ownership
Selecting anaerobic digester mixing systems to obtain the lowest cost of ownership is important for any biogas plant operator. To consistently produce a high rate of biogas production, anaerobic digesters rely on efficient mixing systems to break up scum and solids and distribute them throughout the digester. The cost of purchasing, operating, and maintaining these […]
Food Waste AD – The Anaerobic Digestion of Inedible Food for Energy and Natural Fertiliser
Food Waste AD is the short way to refer to the anaerobic digestion of food waste. In other words, extracting energy from inedible food provides renewable energy and natural fertiliser while diverting environmentally damaging waste away from landfills. That encapsulates the core philosophy of the movement towards food waste AD. “It’s a crying same that […]
UK Food Waste Anaerobic Digestion Plant – Historic 1st Ludlow Digester
In the UK Food Waste, Anaerobic Digestion Plant History began with the dedicated Food Waste AD Waste Technologies Demonstrator Plant, known as the Ludlow Digester, in Shropshire, UK. It was 2004 when the innovative Greenfinch biogas company designed and subsequently built and operated a government-funded plant, opened to process source-separated kitchen waste from council household […]
Better Biogas Production from Wastewater Treatment Works Thickened Sludge
Biogas production improvements that raise the yield of methane from any given quantity of biomass fed into an anaerobic digestion plant are the holy grail of AD. The one thing which, above all else, was holding back the development of anaerobic digestion was the current level of profitability which until the steep energy price rises […]
