As demand increases for alternative fuels, Greasezilla brown grease reclaimers may provide a disposal solution and new revenue stream for large haulers and publicly owned treatment works (POTWs).

Greasezilla recovers brown grease using a low-resource process.

“It’s a two-tank, two-boiler system. They feed in their waste, and it’s heated over a period of time, very systematically, at a rate that creates this separation. After a 24- to 30-hour period, the oil is extracted,” says Roger Sciorsci, national FOG (fats, oils and grease) consultant with Greasezilla. “The best part about Greasezilla is there are no additives; it just works on its own. It is going to make life easier for a lot of these grease haulers and POTWs.”

The system was invented by Ron Crosier, whose father owned a septic hauling company, which he later took over. The dewatering systems the company had been using were not satisfactory. Crosier, an engineering school graduate, felt he could change that.

“After a number of years, frustrated with what to do with grease trap waste, he designed Greasezilla,” Sciorsci says. “So he comes from the same place as the customers we’re selling to.”

Greasezilla’s biofuel byproduct is targeted at the shipping industry. As a biodegradable fuel product used to create No. 6 fuel oil, or Bunker C fuel, it allows large ships to pass emissions testing, which is a challenge due to recent increased standards in coastal waters.

The Greasezilla is fueled by a small amount of the product created in the process, Sciorsci says.

“The boilers are run by 5% of the off-take that it creates, so it runs itself. There’s minimal electrical for the control panels, but other than that, the entire system runs on the biofuel it creates,” he explains. “You could add a second boiler and heat your entire facility with it. That’s also another option we offer as well.”

The main benefit is that because of Greasezilla’s sellable byproduct, it costs less for pumpers and haulers to dispose of grease trap waste.

“The whole idea, the whole strategy, is to reduce tipping costs. These guys are spending some exorbitant amounts to get rid of the grease trap waste,” Sciorsci says. “They’re paying anywhere from 12 to 25 cents per gallon. With Greasezilla, it’s costing them less than 2 cents.”

Access to a Greasezilla may benefit smaller operations, but the system’s potential is really unlocked via in-house use for larger haulers, Sciorsci asserts.

“Depending on their volume, this may be a viable business service,” Sciorsci says. “You’ve got to realize, brown grease is a commodity.”
