Founded 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.
