Dr. Cathy Jim Ka Wai


RHT Industries Ltd.

Graduated from the Department of Chemistry, Hong Kong University of Science and Technology, developed interest in the subject of chemistry since childhood. Dr. Jim was part of the R&D team in the development of NCCO, such technology is a brand-new air purification technology that integrates adsorption and decomposition, so that the filter element doesn’t need to be replaced, while the performance can be maintained. Such technology has reduced the amount of solid waste generated due to filter replacement.

My Sustainability Goals for 2022:

I hope to see more people realize that environmental protection and energy saving is not just a slogan, but a responsibility we should have in our daily lives. The simplest is to reduce the generation and disposal of unnecessary waste.
