NOVELTY - Continuous in-situ triglyceride stabilization of fats, oil and grease (FOG) to optimize fuel extraction involves closed loop aeration to evenly distribute the oxygen throughout both water and FOG in grease interceptors (GI) and grease traps (GT) storage; allowing the formation and continuing functioning of a biofilm; stabilizing triglycerides by arresting hydrolysis; arresting the formation of free fatty acids (FFA's); and microbiologically reducing FOG sulfur content, where the fuel content and quality will be stabilized to optimize fuel extraction and reducing inherent sulfur content.    USE - For continuous in-situ triglyceride stabilization of fats, oil and grease inside grease interceptors, grease traps and other brown grease storage facilities and processing plants to optimize fuel extraction (claimed).    ADVANTAGE - The method eliminates the need for the usual pressure heat treatment and dramatically increases the yield of usable fuel; prevents hydrolysis and thus degradation of the extractable fuel; maintains the aerobic state eliminates odor and toxic and corrosive gases and drastically extends the life of the infrastructure; enables the production of a far superior biofuel at a substantially lower cost; saves resources and chemicals otherwise needed in the production of biofuels; and leverages sustainable water management practices and creates renewable fuels from waste.    DETAILED DESCRIPTION - Continuous in-situ triglyceride stabilization of fats, oil and grease (FOG) inside grease interceptors (GI), grease traps (GT) and other brown grease storage facilities and processing plants to optimize fuel extraction involves closed loop aerating and continuous recirculation of the entire contents of a GI/GT, where the closed loop aeration to evenly distribute the oxygen throughout both water and FOG; allowing the formation and continuing functioning of a biofilm; stabilizing triglycerides by arresting hydrolysis; arresting the formation of free fatty acids (FFA's); and microbiologically reducing FOG sulfur content, where the fuel content and quality will be stabilized to optimize subsequent fuel extraction and reducing inherent sulfur content.
