I was so impressed by your article on biogas.I am from kenya where we have a problem of raw sewage effluent being diverted into the rivers.
i would wont to know how the sewage can be used to produce Biogas and if you have agents in nairobi kenya who you can refer me to.
thank you

I want to venture into biogas prodution. Basically setting up the production plant. Can any body help me with the same. You can contact me at – chinmay.bhatt@gmail.com.
Thanks,

I am interested to Biogas, is there small size of biogas reactor?

i travelled through Asia to Australasia at the beginning of the 1990’s and pitched up in Christchurch, New Zealand in 1992 where someone told me that the city council burned the rubbish and ran the city buses off the gaseous by-product.

At the time this seemed amazingly forward thinking and if true way ahead of the UK, both then and now.. Can anyone tell me if this was in fact the case or just a tall story?

A pleasure to meet you by these email.
Your page is fantastic.Lots of usefull information.
As we are developing our first biogas project in our country we will continue to visit your web page.
Ok,regards from Uruguay South America.

Interesting. I have not looked into biogas lately, but I think that there are (were) issues with scaleup, with anaerobic fermentation. I wonder what kind of subsidies does the Swedish government provide this industry…

I have a suggestion for the title of the article:
“Biogas: Producing Ultra-Efficient Fuel From Sewage” does not reflect what the article is about. IMO, fuels by themselves cannot be termed as efficient, it is the conversion processes that are efficient or otherwise. For example, efficiency of burning natural gas in a fuel in SOFC (solid oxide fuel cell) is higher than that in a conventional gas turbine. Here, the natural gas by itself is not “ultra-efficient”, it is just clean burning (low SOx emissions, low particulates).

Yes, mobile fuel sources are much more valuable than electric generation. Let’s copy Sweeden.

Many large landfills and sewage treatment plants in the US (large being a relative term) capture and combust their biogas in engines. Reciprocating engines are the most efficient use of a gas power supply (turbines would be more efficient), but due to some impurities in biogas, it requires recips and sometimes a bunch of maintenance. In Washington State, the largest landfill powers electric generators and both Seattle’s large sewage treatment plants have similar units.

I love the idea of getting the fuel distributed to mobile sources of air pollution. Now that more of the bus and taxi fleets are running natural gas-fired units, it would be realtively easy to convert to biogas!
