Ng Fung Hong has been appointed sole worldwide distributor for Greencool Refrigerant (Asia) Co, which makes environmentally-friendly refrigerants to replace CFC refrigerants. Ng Fung Hong chairman Mark Chen Shulin said the move marked the latest stage in the company's diversification. Supermarkets owned by Ng Fung Hong have already switched to using the new eco-friendly product. Production of CFC refrigerants has been banned because of its damaging effect on the environment. All CFC production is expected to be phased out by 2000. Greencool has two plants. Its British plant started production in 1994 to supply the European market, while its mainland plant in Tianjin has an annual production of 10,000 tonnes of refrigerant.
