84. From 500 tonnes of cow poop a day comes biogas & ethanol 

Steven Rappolee at some of the UK equivalent plants, the plastic is shredded and goes for “energy recovery” this is basically incineration in a CHP, combined heat and power plant.

Well get enough of them and you can either make material for houses like one company in Colombia or make roof tiles like a company in Africa. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-m7oUk10rKjE.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Zfr0XHYKBvU.html

Gasification or Thermal Depolymerization might work

+zhp500 It is not subsidized yet, but it will be soon! $30/metric tonne of CO2 was the last figure I heard. Clean energy cost more then dirty energy :/

Tell me you don't know anything about biogas technology, without telling me you know what you are talking about. Go. Ok you did - great job.

AT least around here they don't get raised in a feed lot. They only go to the feed lots for the last few weeks before slaughter to fatten them up a bit. It's a for pay service. I agree that all grass fed i tastier and better for you.

DublinDapper: Feedlots is made from grain.

replace feedlot with a tick toc pasture dairy system. you will feel better. i really wish they haven't picked a feedlot

They add food waste

That’ll change if we get taxed on the carbon we produce either individually or the businesses we run.

Ethanol production is 40,000,000 liters per year or 10,580,000 gallons of ethanol. The price per gallon of ethanol is around $1.40 or $14.8-million per year. Add to this whatever amount of electricity they actually feed back into the grid. He said enough electricity for 2,500 homes (@ 04:00). Assuming very efficient homes using 20-kWh per day, this is 18,250,000 kWh per year. At $0.10 per kWh, this is $1,825,000 per year. They, also, add a tipping fee for the municipal waste. They receive about 73,000 tons of municipal waste per year. It converts the manure into potting soil which can be sold to garden stores, and it saves about $0.015 per pound for corn silage. Assuming they provide 20% of daily feed as corn silage, this is (20% x 35-pounds x 36,000 x 365 x $0.015) = $1,380,000. Together it is about $18,000,000 add $10 (my estimate) per ton of municipal waste or $730,000, and add another $0.01 (my estimate) per pound of dirt sold to garden stores ($0.01 x 365 x 1,000,000 = $3,650,000), and the numbers become even larger.

India has this experiment going. Can get info from india youtube

Maybe a little more research in the manure properties. I'm in the Greeley Colorado area building a gas injection site for biogas. Yes it is food that goes in. But the rich manure that fill the digester with H2S gas is only from manure. I just left two sites in NV that are doing the same biogas projects. Only cow manure is used in these digesters.

@@stevenbrent5764 Thanks for the advice. I’m a senior chemical engineer/ project manager who designs and optimized the performance of these and other facilities for a living.

@@stevenbrent5764 You probably meant CH4 not H2S gas. Manure-only facilities function to reduce the BOD of the manure, but can only produce energy if they are processing large volumes of manure.

Hi Lorraine, we love this idea as well. This particular project may or may not be still operating. However we have covered numerous smaller scale stories over the years that really highlight the benefits of this to farmers and the environment. Here is one of our favourites www.greenenergyfutures.ca/episode/31-biogas-closing-loop-cow-poop The trouble is biogas isn't the most economical way to produce electricity. But we think it's more than economic if we factor in the many benefits which include: new consistent income for farmers, radicle reduction in greenhouse gas emissions from spreading manure, the ability to still spread the digestive and get the same benefits on the farm without the GHGs, reduced odors, and reduced runoff pollution.

How ethanol is extract from bio mass?

If you don't mind sharing what would be the missing part in this cycle?

They eat none eatable food products.

VY, don't want to be against human food products but taking grain that was waste and cow poop to make human food products is not very appealing. I work for a company that builds biodigesters for dairy farms none of the cows are eaten but the milk is drunk by all Americans who drinks milk as well as use the power to heat their homes and has the capability of being converted into automobiles engine fuel. No beef here are being eaten, just milked.

@@stevenbrent5764 That's a really a good model. I hope i could visit such a place.
