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 […]
Understanding Aerobic and Anaerobic Digestion – A Comparison
Welcome to the fascinating world of digesting waste! In this article, we’ll be taking a closer look at two processes used to break down organic matter: aerobic and anaerobic digestion. These processes are essential in wastewater treatment and waste management, as they help to reduce the potential environmental impacts of both wastewater and refuse (solid […]
Advantages of Circular Economy
The circular economy is an increasingly popular concept with many sustainability advantages that are gaining traction within many industries. In this blog post, we will explore the 7 main benefits of the circular economy and how it can help businesses to operate more sustainably and efficiently. We will look at how the circular economy can […]
Daily Mail “Slopbuckets Farce” Food Waste Collection Slur 10 Years On
Yes. It is 10 years since the Daily Mail described separate food waste collection as a “Slopbuckets Farce”. And, we can now look back on 10 years of progress in anaerobic digestion technology and operation since we announced that: “WRAP Defends Anaerobic Digestion from “Slopbuckets Farce” Food Waste Collection Slur“. We said: WRAP Defended Anaerobic […]
Waste Autoclave Pretreatment with Anaerobic Digestion for Household Waste
Waste Autoclave pretreatment of residual household waste, and food waste, for all its undoubted advantages in increased biogas yield from the organic fraction, during subsequent anaerobic digestion, has met with a difficult period. The process now has a poor reputation for safety. Since we originally posted our article on this subject in May 2012, the […]
Anaerobic Digestion in the US: 6 Federal and State Incentives and Funding
The use of biogas as an energy source is on the rise in the United States, due to both federal and state incentives and funding initiatives. Biogas is a renewable energy source produced from the decomposition of organic matter, such as food waste, manure, and other organic materials. In this blog article, we will explore […]
Anaerobic Digestion of Whey – The Proven Biogas Technology Solution
Disposing of unwanted whey from commercial dairies, was once a considerable problem. But, that was before recent developments in the anaerobic digestion of whey and biogas plant technology. Instead of a problem whey which is not for any reason suitable for food production has become an asset. During the anaerobic digestion process microorganisms break down […]
