Through a partnership between BlackGold Biofuels and SLM Facility Solutions Nationwide, restaurants around the country will soon be able to more easily recycle greasy kitchen waste while saving money.
BlackGold and SLM have formed a strategic partnership to provide more cost-effective recycling options for hospitality industry wastes. The relationship will enable restaurants, food processors and other buildings with food service to send liquid waste from their kitchen drains and grease traps to be recycled into biofuels, with no additional cost or operational complexity.
BlackGold 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 is positioned nationwide within the hospitality industry, providing the management and consolidation of grease trap and jetting services for commercial kitchens, including the management and diversion of waste streams.
Currently in the U.S., grease trap waste is often landfilled or spread on fields. The material can be sent to anaerobic digestion to produce biogas for energy use, but the digestion process results in the loss of more than 70% of the energy contained in the grease, and few facilities have the expensive infrastructure to convert it into energy. While the grease can be used in limited applications as a heavy industrial fuel, the U.S. Environmental Protection Agency's (EPA) limits on fuel sulfur concentrations will soon make it obsolete.
BlackGold developed a breakthrough chemical process to convert the trash-ridden and highly variable waste into biodiesel that meets the national ASTM specifications and the EPA's ultra-low sulfur requirements. Approximately 80% of the energy content in the waste is recovered. Biodiesel is a low-carbon, low-emission, nontoxic renewable diesel fuel that can be used anywhere petroleum diesel is used, including vehicles, home heating, boilers and construction equipment.
