Carbosphere Inc. is a clean technology firm that transforms non-recyclable plastic waste into valuable industrial commodities, including carbon black concentrates, chemical building blocks for plastics, and turquoise hydrogen.
Carbosphere Inc. is a Canadian clean technology company that has developed a specialized process, known as the CS-TRANFØRM™ process, to recycle mixed, non-recyclable plastic waste. By utilizing KWI Polymers’ technology, the process involves sorting and drying plastic feedstock to remove major contaminants, which is then transformed into hydrocarbon-rich gases and mineral co-products. The system separates condensable fractions for use as chemical building blocks in virgin plastic manufacturing, while non-condensable fractions are processed to generate turquoise hydrogen and high-quality carbon black. The carbon black can be controlled at the nanostructure level to suit various applications, ranging from tire manufacturing to specialized anti-static or conductive uses.
This technology addresses plastic waste accumulation by diverting materials from landfills and converting them into industrial-grade commodities. The company’s approach supports a circular economy by producing value-added inputs for polymerization plants and industries requiring renewable chemical building blocks or clean energy sources. Beyond carbon black and chemical precursors, the process generates mineral concentrates and excess thermal energy, which can be leveraged through strategic industrial alliances to further improve energy efficiency and resource recovery, offering a sustainable alternative to conventional petrochemical and carbon production methods.
