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!

Landia and Plant Operator rest after Biogas digester crust removal by the Landia GasMix mixer.

Biogas Digester Crust Re-dissolved by Landia GasMix Mixer After Propeller Mixing Failure

Biogas digester crust formations floating on the surface of reactor tanks may sound to be of little consequence, but that’s not so according to anaerobic digestion tank operators. furthermore, breaking up and re-dissolving a biogas digester tank surface crust was defeating the best efforts of one AD plant operator recently after a propeller mixer suffered […]

Make COVID-19 Recovery Green Say Business Leaders

Renewables trade associations have added their voice today to the growing consensus that if society has learned anything from the COVID-19 experience, it must be that human life on this planet is fragile. Making the UK’s COVID-19 recovery green is essential from that point of view, due to the huge risks from climate change, but […]

Is My Waste Suitable for Anaerobic Digestion?

“Is my waste suitable for anaerobic digestion?”, is a frequent question we receive in our emails. It comes from those considering installing agricultural AD systems, and businesses that produce food waste especially. There are two immediate considerations for any answer, the first is to say that more or less any organic material can be anaerobically […]

Vertical Long-Shaft Pump Will Blend Cow Slurry At AD Plant

Vertical long-shaft pumps have been around since the earliest days of sewer installation, however, never before did they run this long and deep for biogas plant pump company Landia. Read on to find out more about this case study and how this pump will blend cow manure slurry at an AD Plant in Northern Ireland. […]

Landfill Odour Due to Covid-19 – Operators Urged to Send Organic Waste to Biogas Plants

A rise in organic waste being landfilled due to the Covid-19 crisis is not only contrary to national waste policy, but it is likely to be the cause of a growing problem of UK landfill odour experienced in the last few days. Complaints have been rising in Fife for some time. Similar news is expected […]

Define Anaerobic Digestion: 10 Top Definitions of AD – Listed

“Define Anaerobic Digestion”, said a student to me recently. No doubt because I discovered anaerobic digestion back in the 1990s via my background of environmental biochemistry originally, I quoted the original Wikipedia definition. That one is all about breaking down organic material without oxygen present (ref: 1) and is all about the chemistry involved. I thought […]
