About RHT Industries
RHT Industries is a leading environmental engineering firm committed to developing innovative technologies that protect the environment and improve human health.
Our Origin
In 1999, RHT participated in the Member of HKUST (Hong Kong University of Science and Technology) Entrepreneurship Program.
Through this partnership, we developed the patented Nano Confined Catalytic Oxidation (NCCO) technology.
Unlike traditional activated carbon that merely traps pollutants temporarily, NCCO actively decomposes volatile organic compounds (VOCs) and kills bacteria and viruses, releasing only harmless water vapor and CO₂.
