it was learned from the 19th annual meeting of China Polyurethane Industry Association held on August 1 that the Ministry of ecological environment had launched a special action for law enforcement of ozone depleting substances (ODS) on July 28, and the illegal use of polyurethane rigid foam foaming agent CFC-11 (chlorofluoromethane) would become a key area of law enforcement, The elimination of blowing agent ODS is imminent

according to the introduction, this special action of law enforcement will organize a comprehensive investigation of enterprises in key industries across the country, and adopt a combination of local self-examination and ministerial inspection. The Ministry of ecological environment said that for the raw materials containing ODS found in the inspection, it would track the clues of the source of raw materials and lock down the illegal production enterprises of ODS substances. Clues involving cross provincial issues will be uniformly coordinated and handed over to relevant provinces for joint investigation. Enterprises (individuals) suspected of producing and selling ODS substances will be seriously investigated

recently, Nature magazine published an article pointing out that the decline rate of CFC-11 concentration in the atmosphere has slowed down significantly since 2012, and the increased emissions are likely to come from the newly produced CFC-11, mainly from East Asia. Subsequently, foreign media pointed to the illegal production and use of CFC-11 in China

in this regard, liuyoubin, spokesman of the Ministry of ecological environment, said that the production and use of ODS outside the scope of the Montreal protocol is an illegal and criminal act, which has always been the target of China's key supervision and law enforcement. After the media and relevant agencies reported, the Ministry of ecological environment quickly carried out investigation and law enforcement inspection. At present, the investigation is still in progress. The Ministry of ecological environment has adopted a zero tolerance attitude towards the illegal production and use of ODS, including CFC-11. Once any enterprise in China is found to have illegally produced, sold and used CFC-11, it will resolutely crack down on it according to law and investigate its law until it is normal. The Ministry of ecological environment will also organize a special action to combat the illegal production and use of ODS

China's production of ODS with high guidance accuracy and consumption includes 94 kinds of six categories, which are CFCs, halons, carbon tetrachloride and 1,1, which are worth learning from 1-trichloroethane, HCFC and methyl bromide. According to the relevant provisions of the Montreal Protocol, the Chinese government has issued a ban on the use of chlorofluorocarbons (CFCs) as blowing agents from January 1, 2008. At present, the Ministry of ecological environment has launched the second phase HCFCs elimination plan in the polyurethane industry. HCFC in polyurethane foam industry will be completely eliminated by the end of 2025

Meng Qingjun, Deputy Secretary General of China Plastics Processing Industry Association, said that recently, the special committee has issued an initiative to the majority of polyurethane foam enterprises, composite polyether suppliers and practitioners - to establish a law-abiding awareness and actively use environmentally friendly and low-carbon foaming technology; Consciously do not purchase CFC-11 foaming agent, and do not produce or use composite polyether containing CFC-11; Enterprises that have finished the elimination of HCFC-141b will no longer use it as foaming agent; Actively support the activities of the relevant national administrative departments to combat the production, sale and use of illegal CFCs, and actively cooperate with the relevant law enforcement and inspection work

Yang Maoliang, chairman of the Council of China Polyurethane Industry Association, said at the annual meeting that in 2017, the association undertook the training task of "HCFC elimination in polyurethane industry" assigned by the national environmental protection department. At present, three courses of training have been completed, and experts have been organized to provide technical support and guidance to enterprises
