Last week, I went with a few of my colleagues to visit San Francisco’s Water Pollution Control Plant, where one of the Entrepreneur Showcase presenting companies, BlackGold Biofuels, has a facility that turns sewer grease into biofuel. The grease found in sewers is a big concern for utilities, and San Francisco alone estimates it spends $50 million/year on costs associated with sewer grease. BlackGold’s system not only alleviates the grease problem, it turns it into a profitable product.
Over at the plant, Emily Landsburg, BlackGold’s CEO, and Alexandre Miot, a Process Engineer at the plant, gave us a tour of BlackGold’s setup, which is the first commercial facility of its kind in the U.S.
Once fully commissioned, BlackGold will get dewatered grease directly from this system, a few meters away:
For now, while it is still in commissioning, BlackGold is using these vats of dewatered grease to produce its biofuel:
The dewatered grease goes into the BlackGold system, through which it is made into biofuel.
