Green Energy Biofuel—an award winning, vertically integrated grease collection, processing and recycling company based in South Carolina—seeks talented individuals to fill key positions.
Green Energy Biofuel LLC, a vertically integrated grease collection, processing and organics recycling company based in South Carolina, has been on an impressive growth trajectory over the past 18 years, transforming from a small scale biodiesel producer with a single processing facility in Winnsboro, South Carolina, to a multistate operation providing a variety of services and one of the largest biofuel companies on the East Coast with four locations and growing.
The company, co-founded and run by “head honcho” BioJoe Renwick, is looking to fill multiple key positions with the right people who can help take its operations to the next level and scale. The award-winning recycling firm is currently searching for a chief operations officer (COO), industrial sales manager, operations manager, plant manager at their fats, oils and grease (FOG)-processing facility, sales staff, and a compost sales and service manager.
For the fourth year in a row, Green Energy Biofuel has been named one of the best places to work in South Carolina by SC Biz News. This recognition means a lot to Renwick, and rightly so. “The designation feels good because being chosen for the list depends heavily on an employee survey, so our team members clearly value working here,” he says. “I think this is because of the culture we’ve created. Sure, we pay well, provide 401k, profit sharing and health benefits, but it’s the feeling that we’re a family that our people appreciate.”
The appreciation, however, is a two-way street. Employees enjoy working for Renwick because of the culture, but what the staff provides back to the company is invaluable. This reciprocal respect helps foster an environment where people are loyal and want to work, and where ideas are welcomed and rewarded.
Innovator of the Year
In addition to Green Energy Biofuel being named one of the best places to work in the state, the company has won the South Carolina Manufacturers Alliance’s 2025 Innovator of the Year Award. The prestigious award was presented to Renwick at the 2025 SC Manufacturing Summit held mid-October in South Carolina’s capital city of Columbia.
“I’m still on cloud nine,” Renwick says. “Of all the awards we’ve gotten over the years, this has to be the one I’m most proud of.” The annual awards program, hosted by SCMA and the South Carolina Manufacturing Extension Partnership, honors the state’s leading manufacturers and industry professionals, recognizing exceptional achievements in innovation, operational excellence, leadership and community impact.
SCMA President and CEO Sara Hazzard says the honorees represent the best of what South Carolina manufacturing stands for. “Each one of our award winners—just like each one of our manufacturers—represents the very best in our state’s innovation and creativity,” she says. “They drive our economic achievements, and they are the lifeblood of so many of our communities. In celebrating these award winners, we celebrate the success of an entire industry—and the future of manufacturing across our great state.”
Renwick says Green Energy Biofuel epitomizes innovation at work and sustainability in action. “From recycling to renewable fuel, we’re proud to keep pushing boundaries with zero-landfill solutions,” he says. “Turning waste into energy isn’t just our mission—it’s our promise for a cleaner future.”
SCMEP President and CEO Andy Carr praised the recipients for their commitment to continuous improvement. “The manufacturers and professionals honored today represent what makes South Carolina’s industrial base so strong—they lead with purpose, invest in their people, and never stop striving to be better,” he says. “Their accomplishments elevate our entire manufacturing ecosystem and set a standard of excellence for others to follow.”
Building the Dream Team
While Renwick accepted the Innovator of the Year Award on behalf of his company, he says Green Energy Biofuel staff members are really the ones who deserve the credit.
“We really have a lot of awesome people to talk about,” Renwick says. “The foundation for next-level growth is in place. Now we are ready to bring on experienced managers to push production volumes even higher on grease we originate from the market, refine and sell.”
Green Energy Biofuel has focused much attention recently on building out its grease-processing capability and throughput at the Warrenville facility, as well as vertically integrating ReSoil Compost into the business’ recycling operations and expanding industrial service offerings such as tank cleaning. For instance, this fall, the company sold over 4 million pounds of refined, recycled biofuel feedstock out of Warrenville in a single month. This focus left little room for enhancing the performance and services provided out of its flagship location in Winnsboro—until now.
Green Energy Biofuel recently hired Seth Moon as the operations manager in Winnsboro. “This guy is a machine, he gets it on Day One,” Renwick says. The Winnsboro site is the location out of which Green Energy Biofuel performs all its restaurant service, line jetting, pressure washing and even industrial tank cleaning. “Seth’s role is controlling a big part of our business,” Renwick says. “Seth is changing the whole company and culture on a level we won’t even know for a long time.”
The company has had several employees leave over the years to seek “greener grass” on the other side, but it has been able to bring them back.
Barbara Clark, the operations administrator, was with the company for years. She left, was gone for a few months and was rehired. “She is like fireworks for our plant in Winnsboro—and I shot some fireworks in the parking lot on her first day back,” Renwick says.
If Green Energy Biofuel had a COO, larger sales team and additional management to help carry out its expansion plans, Renwick says the company could really grow. “We’re ready to hire people and even buy competitors—to kick the tires and light the fire,” he says.
Jeff Benton, a long-time friend who helped Renwick build the first biodiesel processor in his garage in 2007 and was hired in 2022, has been recently named director of logistics. He presides over Green Energy Biofuel’s newly established ECB Trucking, whose initials stand for the names of Benton’s three children.
Finally, Suzanne Yates, the company’s human resources manager, was in large part responsible for finding and hiring so many of Green Energy Biofuel’s talented staff members. “I never met a person who works harder than me—until I met Suzanne,” Renwick says. “She is tenacious, and she cares about us so much.”
Renwick hopes to round out the dream team soon once additional management and a full sales team are hired. Having the right people in these key positions takes the burden off of him to land bigger and better contracts. “I can level up and not always have to get dirty,” he says. “Now I can be running the business, not working within it.”
Despite the nearly two-decade-long journey growing from a local, small-scale grease collector and biodiesel producer in Winnsboro to a vertically integrated solid and liquid recycling operation and service provider spanning multiple sites in South Carolina and into Tennessee, Renwick says Green Energy Biofuel is just getting started.
“It’s just the beginning for us,” he says. “We have big plans to unveil over the next six to 18 months and I can’t wait to share them when the time is right. Stay tuned.”
