A standard Greasezilla® system with two 10k gallon reactors can process 6-8 million gallons a year and be profitable processing as little as 2 million gallons a year depending on input characteristics. Contact company for a system calculator.
Greasezilla® fuel trades on the Jacobsen commodity exchange as Brown Grease, an advanced biofuel with a moisture content of less than 1%. It is a drop-in substitute for bunker fuel #6. However, Greasezilla® fuel burns much cleaner than bunker #6 and is increasingly in demand as a feedstock for biodiesel manufacturers and the maritime industry. Greasezilla® burns 5% of the fuel it creates during processing and may also be used for other heating applications in the client’s facilities or processes.
The historical 5-year range for Brown Grease is $0.75 – $2.00/gallon. Downey Ridge Environmental can provide turnkey management of Brown Grease sales as a service to our clients. Optional heated fuel tanks for pre-market storage available.
Since Greasezilla® occupies a small footprint of only 1000 square feet (100 square meters) most applications are housed in existing facilities. The system also comes in a containerized modular configuration for exterior placement.
During normal operation with the reactor cover closed, negative air pressure within the reactor tanks forces odors through internal carbon filters within the closed system. Customers may opt for a simple charcoal air scrubber to diffuse minimal odors noticeable when the reactor cover is opened, however that is not required.
Greasezilla® consumes approximately 4 gallons (15 liters) of GZ fuel per hour during processing. There are minimal electrical needs associated with pumps used to fill and drain the reactor tanks and solid-state circuitry employed by digital controllers.
Minimal preventative maintenance consisting of cleaning, burner nozzle replacement and pump lubrication is recommended. Turnkey wear part replacement kits are available through Downey Ridge Environmental for nominal cost.
Varies dependent upon input characteristics and decant process. Greasezilla® does not affect BOD levels beyond removing high BOD brown grease from the grease trap waste. Greasezilla® reduces BOD to extent that brown grease is removed, leaving pasteurized water and effluent for minimal further treatment.
After processing approximately 80% of the volume in a 10,000-gallon Greasezilla® reactor tank is pasteurized effluent water, ready for headworks of a treatment plant.
The small (approx. 5% by volume) brain or batter layer is an excellent feedstock for anaerobic or co-digestion, or composting. If neither is utilized, then traditional methods of treatment can be utilized, or it can be processed with the effluent water.
