FOG-to-biodiesel
BioFuelBox announced removal of a key technical obstacle that prevented wide-scale conversion of waste greases into biodiesel for nationwide on-road applications – removal of sulfur to meet on-road ASTM specifications. This standard requires all transportation fuels to contain less than 15 ppm of sulfur. Many wastewater treatment plant operators face challenges with messy waste greases, and many of the available waste-grease-to-fuel solutions today run into a glass ceiling due to high sulfur contamination found in certain greases.BioFuelBox Corp., San Jose, CA, 888-383-5269, www.biofuelbox.com
