The Greasezilla grease-separating unit enables grease-trap pumpers to reduce and better control waste disposal and fuel expenses, create a new revenue stream while running a more eco-friendly operation, and it produces its own fuel: brown grease, a byproduct of the separation process.

Here’s how the system works: Pumpers first let gravity separate the water and the grease, then drain the water into a municipal sewer drain. Then they either pump or gravity-feed the remaining grease and sludge into a 10,000-gallon Greasezilla tank. Grease traps typically have a water-to-sludge ratio of 3:1 or 4:1 and brown-grease content of 3 to 5 percent.

A boiler then heats the tank contents to a temperature of about 160 degrees. In about 24 hours, the contents separate into four distinct layers: rich brown grease, an increasingly valuable commodity in some regions (used for biofuel or animal-feed stock); debris; water; and food particles. The brown grease can be pumped out and sold while the remaining content, which is pasteurized and nearly oil free, can be land-applied or discharged into a sewage treatment facility. The Greasezilla unit runs on brown grease; about 5 percent of the brown grease produced in each batch is pumped back into the system and used as fuel.

A typical Greasezilla setup includes dual 10,000-gallon, double-wall, insulated steel tanks. Two tanks increase efficiency because trucks can dump grease in one while the other is processing a load. A full tank weighs about 95,000 pounds, so any commercial building with a concrete slab should be able to handle the weight. The unit requires no special electrical upgrades, he says.

Greasezilla eases the financial sting of increasing disposal fees, labor costs and transportation expenses associated with trips to waste treatment and water treatment plants. In addition, it helps pumpers generate another revenue stream by selling brown grease and/or processing grease for other pumpers.
