Japan's new biogas plant will be fuelled by 250 metric tons of cow manure every day

That's a lot of **** for relatively little power output. does Japan produce that much crap or are they importing it? Didn't think they'd have that much of a cow industry to produce so much ****.

Best steaks in the world IMO.



That's gonna be expensive poop too.

Article reminded me, at some stage the WC Gov launched kind of the same waste to energy pilot project...

http://www.fge.co.za/ --- can not find updates on the project.

Hmm, good point. Still the amount of energy isn't much.

I had a brain fart there. A few more of those and I could get my house off load shedding.

You could run a whole farm off it so food production can be cheap and not linked to elec and fuel prices.

Biogas - Domestic Digesters

I have been looking at this and I wonder why they haven't attempted a small scale gas turbine that can be fed by animal or human waste (or the gas biproducts)

It seems to solve two of the problems we have.

Ignorant, never heard of Japanese beef

Smart idea compared to places like nz that want to tax cow farts

I know a guy who modified his generator to run on LPG, pretty sure it could use biological gasses instead.

Probably. They should be able to run generators on methane but perhaps there is an extra part here that makes it more complex.

Looks like we are actually doing it with landfill waste, wonder why we don't hear more about this project.

The plant will process 480 tons / day of MSW using mechanical means to extract the organic fraction. This organic fraction of MSW will be supplemented with 70t/day of pure organic waste and processed in an anaerobic digestion (AD) plant to produce approximately 1,250 Nm3 / h of biogas. After H2S and VOC removal, and further upgrading, the biogas will be separated into its two main components – biomethane and CO2. After compression to 250 bar the biomethane will be tankered off site as CNG, and the liquid CO2 will be stored on site at -25°C, ready for dispatch to industrial clients.

Buckminster Fuller designed a toilet system in 1936 - a waterless “Packaging Toilet” which separated urine and excrement, and shrink-wrapped the latter to be picked up later and sent to a biodigester. If all toilets were connected to such a system we could literally generate electricity from our ****. Would also save a lot of water. Ordinary toilets use around 11 litres of clean drinking water per flush. If we assume 3 flushes per person per day, you're looking at around 12045 litres of water per person per year, flushed away with our ****.

Hmmm, rushed into with limited technical knowledge and spurned assistance; plant hasn't operated well. Problem is too much inert waste (sand etc) and waste with variable moisture content and calorific value, last I heard. Digesters don't like big variations. Gas produced is high in sulphur and needs cleaning. But open to update and correction.
