BioGas Production

[natehale1971]

I was wondering about the Biogas... it it the same as the Biodesiel? I had read somewhere about an additive that could be used that would cause petrol-based fuels to go further.. has anyone else heard about this?

Gas is an American colloquialism for petrol isn't it? I think what we are referring to when we talk about Biogas is methane/propane type fuels that are actually gaseous at sea level pressures, not liquid petrol. Biodiesel is usually vegetable oil or animal fat (plus additives).

The raw materials required to produce one liter of alcohol fuel
are 1 kg of organic matter and 1 liter of water. These are combined
to produce 1.75 kg of mash, the basic organic mixture that will be
fermented and distilled.

The raw materials required to produce one liter of biodiesel
are 1 kg of vegetable oil, 0.12 liters of ethanol or methanol, and 1
unit of production chemicals (acids and catalysts). These amounts
scale linearly, so a 500-liter batch requires 500 kg of vegetable
oil, 60 liters of alcohol, and 500 units of production chemical

Targan is spot on - Biodiesel is, loosely speaking, diesel fuel produced by recycling used vegetable oils (from restaurant fryers, potato crisp makers etc) or by using treated rape seed or palm oil. Biogas is the production of methane from biological waste materials including animal poo.
