Our Technology is Sustainable

Our NCCO technology is sustainable in many aspects, where our air treatment process is kind to the environment by not releasing any secondary gaseous pollution into it, and is super eco-friendly when disposing of our technology at the end of its life where there is a natural and non-polluting decay of the filter matter.

CSR Value

RHT is actively involved in corporate social responsibilities, as the leader of the industry, sustainability is one of our key focuses. We are committed to a mission of sustainability by incorporating ESG factors at company policy level. The first ever project since our establishment was to collaborate with HKUST (Hong Kong University of Science and Technology) to develop patented technology NCCO (Nano-Confined Catalytic Oxidation) which tackles air pollution with an innovative approach. NCCO is eco-friendlier and more sustainable compared to other options in the market, which typically uses activated carbon filters with an average service life of 3 to 6 months. This soon creates secondary pollution and industrial wastes. NCCO technology is tested to have a lifespan up to 12 years, which significantly reduces the pollution and wastage in the process of air purification.

It is our commitment to fulfil social responsibilities, our mission is to provide better, innovative solutions for general public by working with big institutions. Our projects such as MTR toilets, smoking lounges of Hong Kong Airport, main Building of HSBC have benefited the mass public. Apart from educating the public on air purification and healthy lifestyle, RHT also stands with public in fighting COVID-19.  We have worked with Jiangsu Centre for Disease Control and Prevention to test NCCO’s effectiveness in eliminating COVID-19 particles, which had a proven success rate of 99.99%.

We rise to the challenge of making a positive difference – at environmental, social, policy level. By turning our innovation into products that are sustainable, eco-friendly and effective, we make sure to bring positive impacts not only to our company, but the society,  environment and better future.
