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 […]
What are Biogas Plants? – Digesters Explained with Examples
So, what are Biogas Plants? Biogas plants are systems that use organic waste to generate renewable energy (biogas). Biogas is a gas mixture composed of methane, carbon dioxide, and other gases formed when organic matter decomposes in the absence of oxygen. Anaerobic digestion is the process of producing biogas from organic waste. 1 – An […]
Gobar Gas the Benefits of Gas from Dung
Gobar gas is also known as “Bio gas” or simply “biogas”. Its main component is animal dung (gobar – India) along with some other organic matter like dead remains of plants and animals. It can be used for cooking, electricity generation and heating purposes. How Does a Gobar Gas Plant Work? A gobar gas plant […]
Advanced Conversion Technologies Extract Energy from Waste – AD Rivals?
Advanced Conversion Technologies is the term for technologies such as gasification and pyrolysis. These could become competitors with Anaerobic Digestion. In fact, a number of innovative advanced, high-temperature processes for Energy from Waste/ Waste to Energy, are beginning to emerge from the far east. Extracting Energy from Waste Provides a Sustainable Source of Energy Advanced […]
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 […]
Introduction to the Dairy Farm Biogas Production Process
The dairy farm biogas production process begins with the collection of manure and other organic materials from the farm. The organic materials are then mixed with water and degraded by bacteria to create biogas. The biogas is then pressurized, cleaned and purified to grid quality and used to power facilities on the farm. That in […]
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 […]
Mass Extinction in 2100 – Is UNFCCC’s Warning – Implement Biogas Decarbonization Now!
Concerned about accelerating mass extinction in 2100, and subsequently? Read this to find out how maximising biogas production now is an essential tool towards the decarbonization of Europe. By decarbonising quickly the benefits accrue over the years and provide much more benefit in reduced temperature rises, than by doing this later. Scroll down to read […]
