What’s the difference between trap grease and fryer grease?
Trap grease is very different from fryer oil (also known as used cooking oils or recycled vegetable oil). Fryer oil is from a restaurant’s deep fryer. When it comes out of the fryer it is put in special containers and collectors often pay restaurants for this cooking by-product. The fryer grease is then sold as biodiesel feedstock or as an animal feed additive. Trap grease is grease that has gone down a drain in a restaurant and been captured in an underground sewer grease trap or interceptor. Restaurants pay pumpers to take this odorous, contaminated waste away. For more on trap grease, click here. I make biodiesel from virgin oils and/or yellow grease – can I easily switch to trap grease? Chemically, trap grease and other brown greases are very different from yellow grease, and unique conversion technology is required. BlackGold’s engineers can evaluate whether your biodiesel production facility can be cost-effectively retrofit with our proprietary technology to process brown greases
