News

This category is the place for anaerobic digestion and biogas news and developments.

Today anaerobic digestion (AD) news is all about is the environmentally-sustainable way of generating biogas from plants and wastes.

Many news items stem from the fact that anaerobic digestion systems can be very different for example material may be fed into a reactor in distinct batches, or in a continuous flow.

Anaerobic Digestion News

News and analysis of anaerobic digestion markets, facilities, projects, technologies, companies and government policies.

There are a number of news items that have been posted for a variety of UK food waste anaerobic digestion projects which show that Anaerobic Digestion UK is growing. This news seems to confirm the gradual growth of business in the AD sector.

There will be more news of the UK ETS Scheme as final deals are made. Bioenergy and EfW investors say the move is the next “logical next step”.

Many people love cooking with gas, but what if you could make your own supply, using leftover food waste? Look out for more news of developments in this area as well.

In principle it is simple; you put organic matter into a reception vessel with bacteria and it will produce gas. That is why it is often, not always correctly, likened to a concrete cow. The more you seek to optimise this living structure and its gas production, however, the more complex and sophisticated the system becomes. While the feedstock delivers the gas, it needs the right environment to maximise results and that means paying attention to tank design. As with all things practical, form reflects function.

There are a number of news items that have been posted for a variety of UK food waste anaerobic digestion projects which show that Anaerobic Digestion UK is growing. This news seems to confirm the gradual growth of business in the AD sector.

A few years ago there were UK biogas plants starting construction at the rate of at least two a month, and the industry was even then disappointed and thought the rate should be higher. The news must get better on that over the next few years.

The news is that AD benefits many different groups; including the local community, industry, farmers and energy entrepreneurs, government and the environment.

There is also a demand that in future there will be better AD of solid waste, and by that, we mean smaller, more compact digesters which create much higher gas yields. There is progress being made with a number of promising technologies being used and we will be expecting news on this subject.

We will no doubt also be reporting on how sustainable is an anaerobic digestion biogas plant? The increasing substitution of fossil fuels, such as natural gas, by biogas, would dramatically improve the climate balance.

A THRIVING anaerobic digestion industry is vital for the development of a truly circular economy in Scotland, according to the chief executive of the Anaerobic Digestion and Bioresources Association.

“Returning nutrients from food and other organic materials to the soil, so they can improve soil quality and support food production, is the kind of closed-loop approach we need.

About to come is news of a big increase in recycling and reuse, more food waste being recycled, less waste going to landfill, and especially less climate-harming biodegradable waste,” said Iain Gulland, chief executive of Zero Waste Scotland.

“This has been achieved with hard work from local authorities and others, as well as the growing understanding of the importance of recycling and waste reduction in homes and businesses.”

Increasingly, waste has value. The AD process recognises that and turns things we don’t want, like food waste and farmyard slurry, into something we desperately need – clean, affordable electricity what could be more newsworthy than that!

Green Gas Levy: Biomethane Plants Tariff Scheme Will Fund UK Biogas Plants

The UK Green Gas Levy is going ahead, which means that this new Tariff Scheme will help fund new UK biogas plants. The UK government has confirmed that a charge on gas suppliers will be implemented to fund grid-connected anaerobic digestion (AD) facilities across the UK. Plans to use a new carbon tax on UK […]

Pig Farm Biogas Plant Output Increased 10% While Reducing Impact

We welcome this news that an innovative US Pig Farm Biogas Plant operator has raised its biogas output while all else remains constant by more than 10% simply by installing more efficient pumps. We have written previously on a number of occasions about these pumps. These days hardly a week goes by without another technology […]

Digestate Separator Successfully Removes Plastic Packaging Waste from AD Plant Slurry

With the massive public concern about plastics entering the environment today’s news of a new digestate separator device that successfully removes plastic packaging waste, is very good news. It removes bits of food waste packaging, and other unwanted materials from entering the digester, and from the slurry which pours out of all wet-process biogas plants […]

Biogas from crop residues, not the grain/ food crop.

Use a Biogas Extruder to Make Biogas from Straw Not Food – Biomass Bioextruder™

The Biogas Extruder: Until now making biogas from straw and other similar grain crop residues has been considered uneconomic by the AD industry. But, that was before the advent of bio extrusion technology, and specifically the biomass Bioextruder™. The use of any food crops for energy production often attracts public criticism. This is despite the […]

Combined Heat and Power Systems (CHP) – 3 Important Considerations for Design

Combined heat and power systems (CHP), are also known as co-generation systems, and they greatly improve the usable energy output from electricity generation systems. When a gas engine or turbine is used to generate electricity without CHP, after the electricity leaving the site, there is also hot “cooling water” that is used to keep the […]
