[Stoves] the price of bottled gas

[Anand Karve]

Dear Paul,
I read the article on pig rearing and using the pig shit for raising worms
and fly larvae. It would work in villages, but not in the cities. Our
biogas system uses urban domestic biodegradable garbage as feedstock.  This
material is causing a lot of difficulties to our municipalities. People
have tried the vermicompost route of organic garbage disposal, but in the
cities they do not know how and where to use the vermicompost. That is why
we advocate the conversion of food and kitchen waste into biogas. In our
process, 1 kg (dry weight) of human food waste yields almost 1`kg biogas,
leaving no disposable residue behind. It contains about 360 to 370 g
methane, having calorific value of about 4200 to 4300 kcal/kg, matching
almost the calorific value of wood. Our biogas process is not patented. We
encourage people to copy it and we estimate that almost 10,000 biogas
plants of our design are operating all over the world.
Yours
A.D.Karve
