Process removes sulfur roadblock to grease to biofuel conversion

BioFuelBox Corp. has announced the removal of a key technical obstacle that has prevented wide-scale conversion of waste greases -- including those collected from sewer systems -- into biodiesel for nationwide on-road applications.

SAN JOSE, CA, January 30, 2009 - BioFuelBox Corp. has announced the removal of a key technical obstacle that has prevented wide-scale conversion of waste greases -- including those collected from sewer systems -- into biodiesel for nationwide on-road applications.

"Historically there have been many challenges producing biodiesel from waste greases. Over the last 5 years the BioFuelBox team has systematically addressed each of them and has recently overcome one of the most daunting – the removal of sulfur in order to meet on-road ASTM specifications" said Steve Perricone, President and CEO of BioFuelBox.

The on-road ASTM standard requires all transportation fuels to contain less than 15 parts per million (ppm) of sulfur. The technical challenge has been using a non-food feedstock, like messy waste greases with extremely high quantities of contaminants including sulfur (in the range of 500 ppm or more) for the creation of a tightly regulated, clean-burning renewable fuel.

BioFuelBox's proprietary process was designed from the ground-up to deal with conversion of low-value waste feedstocks into fuel. Sulfur and other contaminants are systematically removed along the process flow using several proprietary technologies.

"With sulfur removal occurring at several process nodes, we ensure a consistent biodiesel product from variable input feedstocks" said Greg Anderson, Chief Scientist at BioFuelBox.

With the ability to cost effectively remove sulfur and other contaminants from waste greases, BioFuelBox paves the way for use of a wider array of feedstocks including fats, oils and grease (FOG) derived from waste sources. Until now, these materials were either land filled or incinerated without capturing any of the energy potential inherent in them.

BioFuelBox is an alternative energy company focused on converting waste fats, oils and greases into ASTM quality biodiesel by means of modular bio-refineries that are resource efficient, flexible and scalable. These modular bio-refineries can be rapidly deployed and co-located next to feedstock supplies, allowing companies and communities to convert waste streams such as brown grease, trap grease and waste water sludge into biofuels.
