Make Sure it’s Biodiesel! ASTM D-6751
Biodiesel Checklist • Meets ASTM D 6751 Standards • Fuel filters • Cold weather precautions • Engine compatibility • Wipe spills immediately • Sore rags in safety can • Use within 6 months
Making Your Own Biodiesel • Safety • Compliance w/ environmental regulations • Feedstock availability • Time commitment • Economics • Handling of byproducts • Engine performance
Transesterification Fuel-Grade Biodiesel Feedstock Oil Methanol Catalyst Drier Water Reactor Washer Separator Raw Biodiesel Wash Water Glycerol (with methanol) Glycerin
Glycerol Landfill as hazardous waste Dispose in anaerobic manure digester Industrial incineration at temperature > 500 F Special permission from PADEP required Land application prohibited by law! Glycerin (after methanol removed) Composting Use as an ingredient for: Degreaser Soap Dust suppressant Animal feed Disposal Options
Disposal Options • Wash Water • Public sanitary sewer (with permission) • Must be prevented from entering waterways, storm sewers, and water runoff channels • Contaminating waterways with wash water is illegal
