What type of waste? (Please don't tell me hog manure... Smell remediation will cost more than the energy you are looking to produce and Seimens will be happy to take your odor control money).
Will you please define "power plant"? Do you mean electrical energy production?
If you mean animal waste, it is best used as fertilizer, as it is really compost; not feedstock for an electric power generator. If there was any way shape or form of making beer, feeding it to cattle and then using it for power generation; Budweiser and ADM would already own your US farm. (They may already be looking you over, while real estate prices are down.)
Here's what a most impressive Canadian cattle operation is doing. (Keep in mind they spent more money than most farms would recover through energy production for 20 years to achieve these results). Are they concerned with self sufficiency?? I don't think so, but you can be the judge.
Here is the link the following article was taken from, as reference: http://www.lho-ontario.ca/tours.htm
According to the Ontario Large Herd Operators
Stanton Brothers - With 1800
freestalls this is the largest dairy on a single site in Ontario. The
1075' long four row head to head barns feature mattress stalls. Alleys
are tractor scraped while the 2 x 30 Westfalia herringbone parlor and
holding and handling areas are flushed into a recirculating transfer
system. An 8 cell 37,000 cu ft capacity anaerobic digester is under
construction. When completed it will provide 250 Kw of electricity as
well as hot water for washing and dried digester solids for bedding. A
gas heated, practical design calf barn is also featured.
*******************
So, when you can afford to house 1800 head of cattle and you have tractors for scraping the yard, the 37,000 cu ft 8 cell digester, and an electrical engineering school to design your farm; just take the Canadian Farm Tour, and they will show you how it's done first hand.
Unfortunately, the cost of producing these energy "saving" technologies and systems is far from cheap and NEVER free.
"When you have lemons, you make lemonade not electricity; unless you're stuck on Gilligan's Island, then you need coconuts or you're "shirt" out of luck".
Feed is of municipal solid waste and converting it to electricity. Calorific value for organic waste is 7,000 btu/lb and biomass boiler efficiency is 35%.
Sorry to have been so blunt in my previous post - thing is, you can't ask that kind of question, and expect a sensible or relevant answer, without giving a lot more information. Your second post is a bit more like it.
I could have equally answered "Yes." to your original post, as there are no doubt many formulae, some known and some unknown, depending on the type & size of of plant, type of waste etc.
Pax vobiscum.
