Founded in 1997 around catalytic-converter materials, AirFlow Catalyst Systems develops and manufactures low-temperature emissions-control systems for diesel and other compression-ignition engines. Its chemistry-centered work is aimed especially at mining and marine equipment, with internally managed development and application-specific designs rather than a one-size-fits-all system. The company also produces custom washcoats and coatings, drawing on a proprietary formulation based on a NASA license.

Paradigm Emissions TechnologiesFounded by John H. Erbland, Rochester-based Paradigm Emissions Technologies designs and manufactures patented plasma pollution-control systems that remove particulate matter from diesel and gasoline engine exhaust. Its compact pass-through reactors are built for both fleet retrofits and integration into new engine designs, helping protect EGR and aftertreatment components while reducing fuel and maintenance costs. The company received a $256,000 National Science Foundation SBIR grant in 2022 to advance plasma-reactor research for high-temperature diesel exhaust.ROCHESTER, NY
Starfire Systems, IncFounded in Glenville in 1988, Starfire Systems develops specialty materials that transform polymers into high-temperature ceramics through its Polymer-to-Ceramic technology. Its silicon carbide-forming chemistry, including the flagship SMP-10, supplied material for NASA’s NOAX repair system used on subsequent Space Shuttle missions. The company also produces specialty silane fine chemicals and continues developing ceramic precursors for demanding applications such as hypersonic and re-entry vehicle components.SCHENECTADY, NY
EnvironexFounded in 1990 by catalytic reaction engineering expert Dr. Robert Becker, Malvern-based Environex provides independent engineering, consulting, and laboratory services for catalytic emissions control systems. Its team of chemical engineers, scientists, and laboratory technicians brings more than 140 years of combined experience to SCR and CO catalyst performance, while also developing customized ozone-destruction catalysts for applications such as cabin air and indoor air quality. Unlike a catalyst supplier, Environex does not sell catalyst products, allowing its recommendations to focus on system performance and long-term operating needs.333413MALVERN, PA
NexcerisNexceris develops and manufactures custom catalysts, electrochemical materials, components, coated structures, and testing equipment. Its capabilities include materials synthesis, catalyst forming and coating, electrochemical component fabrication, pilot-scale toll manufacturing, and validation testing for sustainable aviation fuel, hydrogen, specialty chemicals, fuel cells and electrolysis, and stationary energy storage.LEWIS CENTER, OH
