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!

The Clarke Energy Plant

First WwTW Biogas Upgrading Plant Completed by Clarke Energy France

The City of Perpignan is the first in France to benefit from a Clarke Energy Biogas Upgrading Plant at their WwTW (Sewage Works or “STEP”). The plant will allow the city to make the most sustainable use of the biogas produced, through natural gas grid-injection of the renewable gas. The gas called biomethane is equivalent […]

A Biogas Heating System 101 – Boiler Technology, Options and Benefits

A biogas heating system using boiler technology is the obvious on-site choice for anyone running a biogas plant, and these can either: – make use of a Combined Heat and Power System (CHP) Heat Exchanger utilizing the jacket heat otherwise wasted from a reciprocating gas-generator, or – use biogas produced on-site, or delivered from a […]

Small Scale Biogas Plants for Home Cooking Fuel

The use of small scale biogas plants for home cooking fuel is gaining more followers in the developed nations all the time. These small Anaerobic Digestion Plants (or “biogas digesters”) are great for home cooking using the waste food (table scraps) every day from a young family can fuel a gas ring to heat up […]

Optimisation of Biogas Production – 8 Tips for the Best Methane Gas Yield

In our opinion the optimisation of biogas production for improved biogas yield should start with the consideration of the following list of factors which affect the fermentation tank for all wet Anaerobic Digestion Processes (e.g. Continuous Stirred Tank Reactors – CSTRs), and many also apply to dry AD methods as well. This is important because […]

How to Increase Biogas Production – 4 Ways to Improve Biogas Yield from AD Processes

It’s clear that that everyone involved in AD would like to know “How to Increase Biogas Production“. So, we thought we would join-in with our 4 ways which we have been thinking of recently, for standard commercial single stage CSTR AD plants. If the AD (anaerobic digestion) industry reliably increases biogas production above current established […]

What is Pyrolysis? And, Its Pros and Cons Versus Biogas for Energy

We answer the question “What is Pyrolysis” first with a definition and then consider the pros and cons of pyrolysis technology, versus anaerobic digestion and biogas production for energy from biomass. What is Pyrolysis? A Definition of this Process – Used to Extract Energy from Waste The non-technical answer is that pyrolysis is known to […]

Why Biomethane Output Will Rise Despite Government Biogas Plant Subsidy Degradation

We still believe that Biomethane Output will rise in the UK and Europe, despite UK Government Biogas Plant Subsidy removal and degradation. Our original graphic (shown on the left here) which was made to accompany this article now looks over-optimistic for the time. Nevertheless, there are so many reasons why this renewable fuel will be […]
