The only byproduct of the plastic-to-fuel project at the University of Oregon School of Chemical, Biological, and Environmental Engineering is gas. Testing of the process that produces the fuel indicates the gas is not dangerous. If it were, the product lead, Willie E. (Skip) Rochefort, Ph.D., AIChE Fellow, would not be allowing graduate students close enough to continue their laboratory testing without wearing respirators.
Dangerous, no, but there’s an opportunity here: to feed the gas back into the process of producing the fuel. This will make an already inexpensive process even more inexpensive.
