Abstract
We are developing green technologies to benefit sustainable environment, which will enable people and the environment to prosper together. The Center for Filtration Research (CFR) at the University of Minnesota, collaborating with 20 leading international filtration manufacturers and end users, was established to develop green technologies to mitigate PM2.5 and other environmental pollutants. CFR investigators perform fundamental and applied research on air, gas and liquid filtration. The current research projects include indoor air cleaning and Covid prevention, sensors development and evaluation, nanofiber production and modeling, among others. Large scale air cleaning towers are established in Xi’an and Yancheng in China, and two additional towers in Delhi, India. They are developed to mitigate PM2.5 pollutants in urban air. The second-generation tower in Yancheng is developed to reduce not only the PM2.5 but also CO2 in the atmosphere. All these research and development activities are helping to improve sustainable environment.
