Anaerobic Digestion Systems Web Site

We also have a section on Anaerobic Digestion in Agriculture.

“We think that Anaerobic Digestion has a great future amongst the biological technologies which will become the tools for sustainable waste management throughout the 21st Century, working with nature to maintain the natural carbon cycle to the benefit of man.”



Our mission on this web site is first and foremost to provide our visitors with the information they seek, assuming that these will range from those without previous knowledge, to informed student researchers, and also will include knowledgeable professionals seeking detailed technical information.

This is a very wide readership to serve. We hope that we cover this breadth of knowledge, and that by visiting a few pages you will find the general or detailed information you were seeking. If you would like to see additional features contact us, by email, or by feedback by clicking at the top right of this page.

Those new to AD might wish to start by reading our Introduction to Anaerobic Digestion section.

Existing suppliers might wish to see our technology provider table here.

We also, in particular, seek to help in the resolution of real-life feasibility questions, for new site specific applications of this technology. This may be as part of your sustainable waste management planning. Or maybe, on your farm. We have published an eBook on the subject of Anaerobic Digestion Plant Feasibility Studies here which is available for immediate downloading.

Watch othis video showing a US Batch AD Process, and get a feel for the concept of modern AD technology development.

The popularity of AD is set to rise again in 2008, with UK Government and EU support.

Why not email us and tell us about your AD Project at info@anaerobic-digestion.com , and if we think that the information is of interest to our subscribers we will post your news to them, and your item will also appear on our AD blog. With the rising number of our subscribers this is becoming very useful publicity.

Watch this Video showing a small scale compact digester for producing biogas from food waste in Pune, India. Contrary to the image which AD has in the developed nations AD Plants do not have to be huge and technologically complex.

We are fast becoming a recognised independent web community resource in AD. Please contribute and help us to make this web site better.

Anaerobic Digestion (AD) is a process whereby organic waste is broken down in a controlled, oxygen free environment by bacteria naturally occurring in the waste material. Methane rich biogas is produced thus facilitating renewable energy generation. As a result, materials that are currently going to landfill can be utilised; natural methane emissions are reduced and conventional generation with its associated carbon emissions is displaced. The residual nutrient rich liquor and digestate is suitable for use as fertiliser on the farmland surrounding such a plant, reducing the need for artificial fertiliser.

Anaerobic Digestion is a form of composting. Generally, the term composting is used to refer to aerobic composting. Find out more about composting at our associated commercial composting web site.

(Anaerobic Digestors are also called bioreactors, or biomethanation plants.)

Anaerobic Digestion News Updated : China Soon to be No. 1 in Renewable Power China is poised to become a global leader in renewable energy in the next few years, the head of environmental research group Worldwatch Institute said recently."I think China will be number one in less than three years in every renewable energy market in the world" - Worldwatch president Chris Flavin said. "I am becoming increasingly confident, in the case of China in particular, that there is going to be an ability to make the transition to being at the forefront of innovation, despite contradictory forces at play in the world's most populous nation."He added - "On the one hand, China is close to passing the US as the world's biggest producer of carbon dioxide - and, at the same time, it is becoming an innovator in the field of renew...

Here's hoping for a great new year for Anaerobic Digestion and biogas projects generally.Here is a rallying call to all for the start of 2008...Considering that about 60 % of the total amount of UK animal manure could be handled at biogas plants in future, the potential of primary energy from biogas is a small but significant percentage of the UK renewable energy target.Using renewable energy from biogas eliminates greenhouse gas production and reduces the use of non-renewable fossil fuel. So why is this target not being pursued more vigorously by the UK government?Gordon Brown introduced the possibility in the Climate Change Bill of raising the target for cutting carbon emissions by 80% by 2050 (NCE Magazine...

WebMaster, Steve Last reports:

“Until about 2004 Anaerobic Digestion was considered by most in the UK to be little more than an interesting sideline to sewage treatment and of only academic interest to the waste & agricultural industries. “

“This changing rapidly during 2006/6 and we now receive many enquiries, and have several active projects in this area. We expect that many more will follow.”

WHAT THE NEWSPAPERS SAY!!!!:

“Sheep and cows bred to be less "windy" could have a crucial part in fighting global warming, according to Sir John Houghton, a climate change expert. Flatulent livestock reportedly contribute up to 30% warming”.

WHAT OUR VISITORS ARE SAYING:

Brett Spiller:
This layout of the website is intuitive and therefore easy to navigate. I have found both the depth and breadth of information available very useful.

D.K: It is a very informative site, gave brief information of the technology, particularly plug flow system/UASB, I forsee, that agri farm can be exporters of energy beside their produce, two in one, more cash flow, while keeping the environment protected. India.

Damian D: Excellent website for information on biogas process and outline descriptions. Many thanks. Damian, Ireland.

RV: Good site for general information, good and easy to use layout! Beds, UK

OC: I am in need of block diagram-- how bioreactors are used in bio-methanation?" please help me. India. Try this here...

TB: Why don't you have anything on the anoxic gas flotation process? AGF? US (Washington State University) - Sorry. No knowledge of this. Give us a link, and we’ll publish -Ed.

KT: Great site, well done, however you are not looking at small scale co-operated systems like the Portagester which is an interesting little plant. However, as I have already said, lots of good info for anyone looking at Anaerobic Digestion to perform a number of services. I have also studied AD as an alternative decentralised sewage system and it is very interesting. Unknown location. Good point! See the Portagester process page added Sept. 2007.

J. O’M: Great Site - Very useful information for novice and professional: Ireland

David D: A good site for an interesting subject. Some of the links could be made easier. Regards. United Kingdom

Martino V: A very interesting and useful site. Italy

'Witchaya K: I’m come from Thailand and finding the information about anaerobic digestion in the rural village. I'm studying in master degree and making the project about the anaerobic digestion. Thank you. Thailand

Renee K-B: I am new to this topic in particular but found the site address encouraging and have signed up for the newsletter. US

Nick L: Great website so much useful information, am very much interested in AD with the possible applications and implications. United Kingdom

KSVN: The site appears to be interesting. I am yet to browse thro the site. India

A.G: Biogas production from any viable source is an obvious path in a petro energy stressed economy. My field of interest is on-site wastewater treatment, given GHG concerns carbon sequestering and energy production potential is subject to scrutiny right now. Comment: Relevent, well presented and thus good. US
