I’m looking for an AD plant that can serve a community of 2250 people (individuals not homes). The food waste from the community would be added to the sewage network through in-sink grinders. Digestate would be composted and waste water would go through an MBR and polishing facility.

hello

I am working on an anaerobic digestion plant. i am using a process similar to varlorga process. I have not been able to find the price of a valorga digester till now. anyone has an idea or link where i can get the information. I have tried on the valorga international website endless time with no success.

thanking you in advance.

hello

I am a student in UK and am now on a project to generate max 6MW of electricity through anaerobic digestion for a paper processign plant. I was wondering how much waste material we need and can anyone tell me how to size my digester(s)? Besides I wonder what type of process I shall choose? like Single stage or multistage?

Thank you
salman

Could somebody tell me some of the companies that have completed the Anaerobic Digestion system?

13.5% GHGs is from Agricultural Remains in the world, within these GHGs, most of them are CH4 (Methane), build the Methane recovery system like biodigester to reduce the carbon emission reduction and utilize biogas as power generation fuel or CHP.

I am trying to find a web site that help me to build a an anaerobic digestion system for my home. Does anyone knows where I can find a site?

I have a few questions about this process.
1. What is the production rate?
How much waste is put in to produce 1 days energy?
2. What does it cost to produce 1 days energy?
3. How small can the plant process be?
4. Can it be fitted into a 2 meter cube or less?
5. Can this all be done without compromising vital crops?

We are thankful if you could support how much financing it may attract, and who will fund it. As you say it produces is renewable energy, but the power derived from seem to mot much useful, however under CDM methane generation, is 21 times co2, does this not build higher vlaues of CDM? We are thankful if you can furnish such data also. Where have such installations have taken place? Who has funded it? Please give a few concrete instances, where one can educate further.

Thats true, Michel. Alternative energy systems are inherent to achieve sustainable development, energy-security and address environmental issues in any country. Biochemical methods of waste-to-energy conversion, like anaerobic digestion, should be promoted in a big way.

I think there should be more anaerobic digesters in the agricultural community. They should also be more prevalent in the cities where everyone is producing a fuel source each and everyday.

Hi Chloe
Thanks for your comment.
Apart from anaerobic digestion, there are aerobic as well as fermentation processes to obtain biofuels from woody biomass. It would be more convenient if you can write to me at salman.alg[AT]gmail.com so that I can send you some study material in your field of interest.

Best wishes
Salman

Hiya my name is Chloe, I’m a student at Glasgow University I’m doing a project on utilization of woody materials. I found this article very interesting and I was wondering if there are any other biological methods that can be exploited to release feedstocks for biofuel?

You’re absolutely RIGHT!!!! One American man is doing something about it. He is teaching a workshop about how individuals can make their own biomass or trash gasifier. Check it out in Treehugger.

http://www.treehugger.com/files/2008/08/build-do-it-yourself-biomass-gasifier.php

Great article and the guy is showing people how to build one hands on. If people are real and want to walk the walk instead of just talk green, then they should attend his workshop. Tickets are available according to treehugger by going to VictoryGasworks.com

Bio gas made from sewage and lawn, weeds, and tree trimmings is the answer. We should not be wasting corn, which is so valuable as food and feed, on manufacturing bio fuel. The whole corn-bio fuel thing is a big fiasco, causing world famine and economic strife. The real solution is always to take a problem (sewage pollution) and flip it over to make it a viable solution (a new source of energy). People should be thinking “How can I turn this disadvantage into an advantage?” rather than trying to dispose of it. Yes, find new uses for the unwanted bi-product. That is the proper way to eliminate the problems of pollution without causing other, often greater, problems.

Ram Bux Singh in India invented the Bio Gas Digester back in the 60s. Villages in China run their electric lights from crude bio gas technology, consisting of a pit dug in the ground with a floating lid & pipe on it to collect the methane gas. Rudimentary technology is there now; it’s usable as is, or we can refine it so every backyard has a bio digester. The big question is WHY AREN’T WE DOING ANYTHING WITH IT NOW????
