Business
EcoSimplex Co., Ltd. is a South Korea-based environmental technology and renewable energy company that specializes in biogas capture, waste-to-energy power generation, hydrogen energy infrastructure, and bio-based industrial materials. The company operates through four principal business divisions: Renewable Energy Generation, Hydrogen Solutions, Eco-Friendly Bio-Materials, and Environmental Engineering and Plant Operations. Its core products and services include landfill gas (LFG) power generation and electricity supply; bio-methane and compressed natural gas (Bio-CNG) production; biogas purification and desulfurization systems; bio-hydrogen production facilities and hydrogen refueling station operations, including urban green hydrogen dispensing sites; patented bio-sulfur agricultural materials, comprising organic fertilizers, biopesticides, and soil conditioners; sulfur-based eco-friendly construction additives and industrial coatings; and comprehensive engineering, procurement, construction (EPC), and operation and maintenance (O&M) services for municipal and industrial waste treatment and energy recovery facilities. EcoSimplex serves municipal governments, public utility authorities, agricultural distributors, and industrial energy consumers primarily within South Korea. In recent developments, the company executed a strategic corporate rebranding, changing its name from EcoBio Holdings Co., Ltd. to EcoSimplex Co., Ltd. to reinforce its focus on integrated circular economy technologies and sustainable energy solutions. Furthermore, the company has expanded its clean energy initiatives by scaling biogas-to-hydrogen conversion technologies, participating in municipal and national projects to produce high-purity green hydrogen from organic waste for public transport networks. EcoSimplex has also expanded commercial partnerships for its proprietary bio-sulfur formulations across agricultural and industrial coating sectors and advanced its carbon credit monetization through domestic greenhouse gas emissions reduction programs. Founded in 1989, EcoSimplex Co., Ltd. is headquartered in Seoul, South Korea, and is publicly traded on the KOSDAQ exchange under the ticker symbol KRX:038870.
