Has anyone has any experience with grease trap waste. I am looking into an
idea of collecting grease trap waste and seperating the water from the
grease, then heating the grease to a level where it can be filtered and used
in gas turbines while the water is cleaned up and use for irrigation I know
grease trap waste is very high in FFA but does this atler it total energy
value or just its gelling point.
