What is the difference between yellow grease and brown grease?

Brown grease means floatable fats, oils, and greases and settled solids that are recovered from grease-control devices (e.g., grease traps and interceptors). Brown grease is difficult to reuse, but may become part of renewable energy sources in the future. We do not accept the discharge of brown grease into our sanitary sewer system.

Yellow grease means fats, oils, and greases that have not been in contact or contaminated with other sources (e.g., water, wastewater, solid waste, etc). An example of yellow grease is fryer oil, which can be recycled into products such as animal feed, cosmetics and alternative fuel. Yellow grease is also referred to as "renderable."

No grease should ever be poured down the drain, but should be disposed of in a responsible and environmentally safe manner. Call 937-781-2562 for more information.
