I have made some significant changes and alterations to this page. It required clean up and making relevant. I suggest that anaerobic digestion should be concentrated on that page and not go into depth about digestate here.

This article had become a complete jumbled mess! I have significantly reworked the article again, wikifying it and moving information that distracts from the main purpose - discribing the production, composition and applications of biogas. Although related the article doesnt need essays on the effects of siloxanes on gas engines - these should be in the relevant areas of wikipedia. It does need some focus in expanding sections on landfill gas etc. The tables on EU biogas utilisation are interesting but took the whole article over. I have moved these to their own new article. I have also taken two pictures that improved the very small picture of a biogas bus which wasn't really doing much to make it more visually stimulating.--Alex Marshall 15:51, 4 December 2007 (UTC)

[edit] Conversion into Natural Gas

With natural gas quickly becoming more valuable than electricity, shouldn't we include a section on how biogas can be processed and sold as natural gas? --Flatline 19:29, 20 September 2005 (UTC)

I don't think it's normally cleaned up to pipeline quality levels. I think they just dehydrate it and burn it as is, or burn it after mixing it with natural gas. It is possible to do so, I just don't think that the money spent cleaningfdfsfsdfsdfsdf:Biogas is a side business for farms, sewers and landfills. Biogas plants are a distributed energy source, each plant doesn't produce a huge amount of gas. Usually, there's just enough gas to fire a 0.1 to 10 MW turbine/reciprocating engine (a large power plant is 500-1,500 MW). All of the equipment used to make the gas, treat it, burn it, control pollution... is duplicated at each plant. They don't have economies of scale like big power plants and big natural gas processing plants (that clean natural gas). -- Kjkolb 12:26, 1 January 2006 (UTC)

[edit] Changes, landfill gas

I made a lot of changes to the lower half of the article. If you disagree with them, I encourage you to edit them. Leave a note here or in the edit summary, if appropriate.

I think the landfill gas section in natural gas should be incorporated here and then landfill gas should redirect to this article. If no one objects, I will do so shortly. -- Kjkolb 13:53, 1 January 2006 (UTC)

[edit] Biogas

I saw your comment, I had forgotten about biogas (doubtless others as well), but I'm not sure it is a direct biofuel as it is defined (or as least as it is defined here, I have not seen the term used elsewhere, but it seems useful to have, so I decided to expand it). Biogas needs a different fuel system, and thus engine modifications. Compare to biodiesel which can be used in any diesel engine by just pulling up to the biodiesel pump instead of the D2 pump. (If you can find such a pump, but that isn't the issue here). BluGill 16:25, 26 August 2006 (UTC)

Hi BlueGill I am confused by your definition of "direct biofuel". Biogas can be used directly into a standard gas engine. I understand where you are coming from regarding vehicle transportation but the standard car engine is not the only engine that is available. I'm also not an engineer so I can't get into the specific debate on engines, however I think if you dont accept biogas as a direct biofuel you need to be clear on your engine definitions. Cheers --Alex 16:11, 27 August 2006 (UTC)

Hallo sir i want some more information regard to biogas. Is biogas is use as fuel in vehicles by some chemical process ? and if yes then what process need to be done on biogas to use in vehicles.

Hello there, please create an account and sign your name after comments. I am not an expert on biogas engines however biogas is being used directly into buses and biogas trains. These links might give you pointers to the questions you ask. --Alex 08:36, 29 August 2006 (UTC)

[edit] Uses for Biogas

There are a lot more uses for biogas than electricity and vehicle fuels - in fact these are second last and last uses on my list as they are inefficient, complex and expensive.

I think biogas should be used directly for cooking, lighting or heat if possible. Absorption refrigeration is also possible before using biogas to make electricity (probably to be used for one of the above purposes!). A Combined Heat and Power (CHP) or CoGenerator unit is a bit better use of biogas than simply running a generator. Paulharrisoz 04:55, 20 November 2006 (UTC) Paul Harris

[edit] UFOs

"Swamp gas" redirected here... so nothing about UFO sightings? -70.233.164.27 07:34, 1 March 2007 (UTC)

[edit] Malta

Uhm, why is the statistics for Malta 0? Perhaps this could be changed to a decimal or removed? I can't see the source as my laptop seems to have a problem. ĞavinŤing 06:11, 21 October 2007 (UTC)
