About Us

Alkemy is an advanced materials company at the intersection of materials science, industrial chemistry, and computational intelligence. Founded by Dr. Sophia Bethanis and Peter Kombouras, Alkemy has developed a patented thermochemical conversion process that engineers high-performance ceramic aggregates from a broad range of industrial waste streams including fly ash, mining tailings, waste-to-energy byproducts, air pollution control residuals, and other industrial byproducts.​

​At the core of Alkemy's IP is a proprietary computational algorithm that analyzes the chemical composition of incoming waste streams and generates optimized formulation and thermal processing parameters matched to each feedstock. The result is a consistently engineered ceramic aggregate with precise mechanical and thermal properties.​ Alkemy's ceramic aggregates are engineered to meet custom buyer performance specifications, enabling precise material design for demanding construction, infrastructure, and energy applications. All Alkemy materials are fully certified to EPA, ASTM, and ISO standards, meeting the highest environmental and performance benchmarks in the industry.

Alkemy's materials are engineered for two primary markets: lightweight aggregates for concrete and infrastructure applications, and high-performance ceramic proppants for oil and gas well stimulation. By processing both solid waste streams and air pollution control residue including baghouse particulates and flue gas desulfurization byproducts, Alkemy provides a total upcycling solution for industrial solid and airborne emissions. The result is a scalable decarbonization pathway for heavy industry, permanently mineralizing combustion byproducts into certified structural materials and enabling industrial operators to convert emissions liabilities into revenue generating assets
