What They Do
Green Energy Biofuel specializes in the production of biodiesel from waste cooking oil and grease, employing a comprehensive process that includes collection, cleaning, dewatering, heating, and conversion into biodiesel, which serves as a renewable fuel alternative. The company has expanded its operations to include feedstock collection and sales to other biodiesel producers, enhancing its market presence in the southeastern U.S. (source: gebiofuel.com). Their core technology features a proprietary secondary waste processing method that stabilizes biodiesel operations, allowing for vertical integration and zero-landfill solutions. This innovative approach is exemplified by their acquisition of ReSoil Compost, which broadens their capabilities in organic waste upcycling (source: gebiofuel.com). The company’s products primarily consist of biodiesel produced at their facilities, including a 300,000-gallon-per-year plant in Winnsboro and a 40-60 million-gallon capacity at their GEB3 plant in Aiken, SC.
Projects & Track Record
Green Energy Biofuel has a notable track record of projects, including the establishment of their original 300,000-gallon-per-year biodiesel plant in Winnsboro, South Carolina, which was built from scratch in 2008. They also expanded their operations with a feedstock site in Knoxville, Tennessee, around 2012, and acquired the GEB3 plant in Warrenville/Aiken in 2018, which has a capacity of 40 million gallons per year (source: gebiofuel.com). The company has engaged in collaborations, such as a partnership with ATP-SC LLC aimed at growing biocrops and producing biofuels in Allendale, South Carolina, contributing to the state's bioeconomy expansion (source: gebiofuel.com). Their ongoing operations involve grease collection across four states and biodiesel shipping from their expanded facilities, reflecting their commitment to sustainability and resource management.
Recent Developments
In the past two years, Green Energy Biofuel has not reported any major new contracts, acquisitions, or funding rounds. However, they have maintained a focus on diversification and growth, as highlighted in a December 19, 2023 article from Biodiesel Magazine, which discussed the company's ongoing momentum since its inception in 2008 (source: biodieselmagazine.com). Noteworthy achievements include receiving the 2022 Carolina Recycling Association Annual Recycling Award for their zero-landfill solutions through the integration of ReSoil Compost, which underscores their environmental and economic impact in the biodiesel and composting sectors (source: gebiofuel.com). The company has also been featured in various media outlets for its growth and innovative practices in clean energy operations.
Working There
Green Energy Biofuel offers a variety of roles primarily focused on biodiesel production, grease collection, logistics, and processing plant operations, with approximately 42 employees across four locations as of recent reports (source: gebiofuel.com). The company is actively hiring for positions at their Aiken/Warrenville headquarters and plants in Winnsboro, South Carolina, and Knoxville, Tennessee, particularly in operational and industrial roles to support their growth. The culture at Green Energy Biofuel is influenced by family involvement, with co-owners BioJoe and Dr. Beth Renwick playing significant roles in shaping the company's human resources practices as they scale. The company has been recognized as South Carolina's top high-growth small company, reflecting its commitment to resource management and sustainable practices in a competitive environment (source: gebiofuel.com).
