PHILADELPHIA -- Foodservice operators can now recycle liquid waste from their kitchen drains and grease traps into biofuels thanks to a new partnership between BlackGold Biofuels and SLM Facility Solutions Nationwide. The environmental service will add no additional cost or operational complexity compared to conventional grease disposal, the companies reported.
Philadelphia-based BlackGold Biofuels operates liquid waste recycling facilities that use a patented process to extract and recycle residual fats, oils and greases from kitchen wastewater into biodiesel. SLM (Green Lane, PA) provides grease trap and jetting services for commercial kitchens nationwide, including the management and diversion of waste streams.
Biodiesel is a low-carbon, low-emission, renewable diesel fuel that can be used anywhere petroleum diesel is used, including vehicles, home heating, boilers and construction equipment. Approximately 80% of the energy content in the waste is recovered through BlackGold's treatment process.
Under the new agreement, SLM will direct its 15,000 clients throughout the country to recycle waste with BlackGold, when proximity to recycling facilities permits it to be cost-effective. BlackGold is reportedly building a network of recycling facilities throughout the U.S., starting in the Southeast and mid-Atlantic.
BlackGold's receiving facilities process the material into an intermediate product, which is then converted into biodiesel at centralized plants; this allows waste to be aggregated from a broad geographic area while minimizing freight costs. Plans call for growing the network of conversion facilities as threshold volumes are achieved in the receiving facilities.
The company's first customer, the City of San Francisco, installed the first sewer grease to biodiesel facility in the country at its municipal wastewater treatment plant in 2010.
