Green Car Congress has an interesting article on creating Ethanol From Citrus Peels.
There are lots of stories in the news these days about different approaches for ethanol production. I found this one particularly interesting in that it not only has the promise to produce 80 millions gallons of ethanol a year from the orange citrus waste from Florida alone, but it also promises to produce two other revenue streams from other orange peel by products in the process. I think this type of multi-output production process is something that all manufacturers should be investigating. In our disposable culture, we often disregard the value of the left-overs.
