Biofuel Recovered For Recycling At Restaurants

SAN FRANCISCO, CA - APRIL 05: David Wicks (R) and Glendon Johnson (L) with the San Francisco Water Power and Sewer's SFGreasecycle clean out the filter of a grease collection truck on April 5, 2013 in San Francisco, California. Launched in 2007, SFGreasecycle is a program that will collect used cooking oil from San Francisco restaurants to be recycled into biofuels and also keeps oils from entering the city's sewer system. According to a recent report by San Francisco based nonprofit group Next 10, California continues to be the nation's leader in venture capital funding for green technology, green tech patents and the growth in clean power generation, resulting in reduced greenhouse gas emissions despite a growth in population.
