Green Energy Biofuel improves operations to accept bigger contracts, more food waste

While the U.S. market for green, renewable energy like liquid biofuels made from recycled fats, oils and greases may be uncertain right now thanks to shifting federal tax policies and a new administration, the future of green energy—and Green Energy Biofuel LLC—is certain, according to BioJoe Renwick, “head honcho” and co-owner of the South Carolina-based recycling company.

“Regardless of what the government is doing, we are contracting with new clients, placing new tanks, and growing capacity and scale every month,” Renwick said.

Recent developments at Green Energy Biofuel continue to help the firm fulfill its mission of being the Southeastern U.S.’s premier, vertically integrated organics-recycling company and service provider.

The company owns and operates a large-scale grease-processing plant in Warrenville, South Carolina, a facility that over the years has undergone—and continues to undergo—incremental improvements.

One of the more recent enhancements at the plant includes a complete system to accept and process trap grease.  

“Our new trap-grease processing system includes a boiler, centrifuges and specialty equipment designed to recover marketable grease from the nastiest sludge imaginable,” Renwick said.

As part of the system, the company installed an 18,000-gallon cone-bottom secondary-process receiving tank—bringing total dedicated process tankage to over 150,000 gallons—and a concrete spill-containment transloading pad.

In addition to trap grease, the new tank provides Green Energy Biofuel the unique option to bring in volumes of waste streams with heavy solids and water from tank and railcar cleanings—just one of the many services the company offers its industrial clients.

“In my 18 years of doing this, I have not seen a tank like this before,” Renwick said. “It will serve as a key piece of equipment needed to easily deal with hard-to-accept and hard-to-process wastes.”

Three years ago, the company bought a Depackaging Boss equipped to handle wet or dry food waste in industrial-scale, bulk quantities. The unit is designed to unwrap prepackaged, expired foods such as mayonnaise, salad dressing and similar goods to recover the oil and other organic materials. In February, Green Energy Biofuel set the first of two 34-yard trash compactors needed to reduce energy-intensive trips hauling the remaining inorganic materials offsite four to one, reducing costs and further lowering its environmental footprint.
