LANSING, W.VA, DEC 6, 2019 — Greasezilla™ has been selected by Hampton Roads Sanitation District (HRSD) to provide the most cost-effective and ecologically sound FOG (fats, oils and grease) Separation Technology for the Nansemond Treatment Plant in Suffolk, Virginia. HRSD did an industry-wide search for the most efficient and advanced system to separate FOG into its basic components, sending the water back to the treatment center headworks and responsibly recovering advanced biofuel. The construction of the new facility is expected to begin in Spring 2020.
HRSD and the localities it serves are diligently working with responsible restaurant owners to keep FOG out of the regional sewer system. However, some FOG still manages to make its way into the pipes. Over time, this FOG coats, congeals and accumulates in pipes, pumps and equipment, leading to costly and environmentally damaging outcomes. According to the EPA, 23,000 – 75,000 Sanitary Sewer Overflows (SSOs) occur each year, and the majority are caused by FOG. Even if accumulated FOG does not escalate into blockages and SSOs, it can still disrupt wastewater utility facilities by increasing operations and maintenance requirements.
Jacobs, the leading provider of technical, professional and construction services, will be responsible for placement of the major system components and is overseeing the facility – which will screen, decant and process the FOG from indirect haulers. The Greasezilla system will sit ahead of the wastewater treatment facility and process up to 40,000 gallons per day, which equates to 7.5 million gallons of FOG per year and beyond, as it is completely scalable.
Greasezilla’s two-tank, two-boiler system heats the FOG to create separation, requiring no additives, additional processing, blending or fossil fuels. After separation, the brown grease is pumped into holding tanks and has now become an advanced biofuel that is a carbon positive substitute for high-sulfur bunker fuel (No. 5 and No. 6 fuel oil). It burns clean and has a small physical footprint when compared to corn or soy. The remaining water content, which is pasteurized and nearly free of all suspended solids, is now safe for discharge into the wastewater treatment facility.
Brian Levine, Executive Vice President, Greasezilla, said, “We are extremely proud to be working with the Hampton Roads Sanitation District, as it is recognized as one of the most progressive wastewater treatment facility authorities in North America. Clean water standards in the United States are changing, and the EPA is now referring to Wastewater Treatment Facilities as ‘utilities of the future’. With this project, we are starting to see a transformation in the way traditional wastewater utilities view themselves and manage their operations. These changes benefit utilities while also delivering environmental, economic and social benefits to the communities they serve.”
HRSD provides service to 18 cities and counties of southeast Virginia, an area of over 3,087 square miles with a population of 1.7 million (larger than the state of Delaware). HRSD operates nine major treatment plants and seven smaller plants in eastern Virginia, with a combined treatment capacity of 249 million gallons of wastewater from homes and businesses per day.
Greasezilla provides an environmentally sound alternative to chemically treating, lagooning, landfilling, incineration or dumping FOG waste. Greasezilla’s FOG separation process is powered by the same rich brown grease it harvests, making it an economically viable and environmentally sustainable system. Additionally, it only takes five percent of the rich brown grease to power the system. This provides a significant economic opportunity to sell the remaining 95 percent of the biofuel.
Greasezilla systems are currently in use in North and South America, with more municipalities planning to add the alternative Greasezilla technology into their wastewater facilities globally. As word about Greasezilla spreads, the company continues to extend its reach to countries around the world.
