Researchers at the University of Florida have developed a method to turn sugarcane bagasse (crushed-stalk waste) into succinic acid.  Succinic acid is a building block chemical for pharmaceuticals, coatings and bio-degradable bags, among other things.  Usually succinic acid is petroleum derived.  However, the University of Florida researchers developed a new E. coli strain to genetically engineer the succinic acid from the sugarcane bagasse.  Yet another way to make use of waste and avoid the need for fossil fuel consumption.
