Recycling kitchen waste

Alcohol is a waste product of yeast based fermentation. Carbon dioxide is the other waste by-product of the yeast induced fermentation. Yeast eats sugar.
Alcohol is a pretty wicked waste product to produce. Important notice! Forget about drinking any of the experimental fermentations! If you want to drink the stuff go to a wine and beer store and pick up what you need. Some alcohol can blind and kill you, if you can't tell the difference don't mess around! Experiment feeding yeast sugar and food scraps.
Fermentation produces heat. This is good for a couple of reasons. First yeast metabolism increases with temperature. Second, a room of 50L bottles fermenting could help heat a well insulated home.
Alcohol can be burned. It can be used for cooking, heating, lighting and hot water. Just be realistic about how much alcohol you can get from this one fermentation process.
Carbon dioxide sounds bad as a waste product. I think of the carbon dioxide as a feedstock material for bio diesel projects. I have not heard of any successful algae to bio diesel implementations but there are other carbon recycling concepts that would also benefit from the yeast created carbon dioxide.
Alcohol can also be used for refrigeration through evaporation. If you had a large enclosed evaporation chamber coupled with an alcohol compressor you could make some serious cold and keep your alcohol for another winter blast, another day.
The state of the art for these concepts is really pretty bad. I would say pre hydro carbon man could do this stuff better that I can at this point in time, even with all my advanced technology.
