Compact digester for producing biogas from food waste

The Appropriate Rural Technology Institute (ARTI) in Pune has developed a biogas plant which uses food waste rather than manure as feedstock and supplies biogas for cooking. The plant is sufficiently compact to be used by urban households, and over 700 are currently in use.

Pune is a relatively affluent city in south India, and many people use liquid petroleum gas (LPG) or kerosene for cooking. Waste food is often discarded at the side of the road, as in many cities, attracting stray dogs, flies and rats and creating a public health hazard. The ARTI compact biogas plant is made from two standard high-density polyethylene (HDPE) water tanks: the larger tank acts as the digester and the smaller one is inverted and placed into it to serve as a gas-holder. The plant safely digests kitchen waste, food waste or waste flour from mills, thus reducing the problem of waste disposal. A 1,000 litre plant produces sufficient biogas to at least halve the use of LPG or kerosene for cooking in a household, as well as a small amount of liquid effluent which can be used as fertiliser. ARTI has developed the technology, field tested it, and managed the supply of about 700 biogas plants in Maharashtra. Around 100 plants are now being installed every month.

It is excellent way to get rid of waste around us in India, I would like to know what chemical is added to the ferment the pulpy waste, or if any of the member from ARAti can explain the entire process in detail I will be grateful to them

Great. Notice the black heat absorbing tanks.

In rural china they use animal manure and what goes down the toilet and the system doesn't smell, it's terrific, look up Paul Henderson biogas in rural china on the cityfarmer website.

If you look at the ARTI video you will see why they use food waste and not dung, as the process is 400% faster.

We have a place called Puna on the Big Island of Hawaii. I wish we would use biofuel here as well :-) I'll have to start with myself.

The piled lumber blew across several front lawns before settling over a swelled rushing stream.

Thank you Odziz. Could you provide a diagram of entire system for us?
