Hazardous waste disposal industry stands at the crossroads of reform


      Recently, the reporter learned in the process of investigation, under the increasingly stringent environmental protection policy, the demand for hazardous waste treatment of chemical enterprises across the country has increased, the existing hazardous waste treatment capacity is seriously inadequate. With the intensification of market competition and increasing demand, the hazardous waste treatment industry in China has come to the "crossroads" of great changes.

    Sheng Yongning, chairman of Gansu Provincial Center for the Treatment of Dangerous Wastes, told reporters: "At present, according to China's standards, there are 46 categories of 479 kinds of hazardous waste, mainly including precious metals, waste acids and alkalis, pesticides and other hazards, involving 45 industries. Hazardous wastes are corrosive, toxic, flammable, reactive and infectious. Among them, only one toxicity involved 440 kinds of dangerous waste.

    "At present, the demand for hazardous waste treatment in chemical enterprises is increasing. However, when we contact the hazardous waste treatment unit, it often happens that the treatment unit does not even answer the telephone." Jiang Neng, general manager of Sichuan Northern Hongguang Special Chemical Co., Ltd., told reporters that the reason for this situation is that the capacity of the processing unit has been saturated and can not continue to accept more requests for hazardous waste treatment.

    In response, Zhou Wenwu, executive deputy district director of Nanxi District, Yibin City, Sichuan Province, said that the current solid waste treatment capacity in Sichuan Province is seriously inadequate, especially in the treatment of hazardous waste, large-scale hazardous waste treatment units only 2, unable to meet the needs of enterprises. At present, Sichuan Province is re-planning the disposal of solid waste, and temporarily refuses to accept the application of self-built solid waste disposal, which also has an impact on the disposal of hazardous waste for a period of time after the enterprise.

    In this case, some enterprises secretly landfill the hazardous waste. "If we bury it, we must not. Enterprises should use more professional means, more scientific technology, in the reduction and harmless treatment of progress, do a good job of hazardous waste resource utilization, is a sustainable method.

    China adopts the management mode of approval license for hazardous waste enterprises, which includes the scope of treatment and the approved capacity. China's hazardous waste industry started late, a variety of small and medium-sized companies have entered, but there is not enough technology accumulation, so only a small number of qualifications license. At present, more than 90% of China's hazardous waste disposal enterprises can handle only 5 kinds of hazardous waste.

    Professor Wang Pingfang of Northwest Normal University pointed out: "There are 1,809 hazardous waste disposal enterprises in China, with the disposal scale of up to 1,210 enterprises under 20,000 tons. The industry is small, scattered and chaotic. The market share of the top ten hazardous waste disposal enterprises is less than 10%. According to the license, 62.3% of the enterprises with less than 10 kinds of hazardous waste disposable accounted for, while only 1% of the enterprises with more than 25 kinds of hazardous waste disposable.

    Sheng Yongning emphasized that there are many kinds of dangerous wastes, which are difficult to deal with and require very high technical requirements. Different kinds of hazardous wastes contain a wide range of hazards, so each kind of hazardous waste requires different disposal techniques and qualifications. However, due to the lack of sufficient technical capacity, small and medium-sized enterprises are prone to deal with non-standard and incomplete phenomena, resulting in secondary pollution to the environment.

    In addition, Sheng Yongning introduced that there are 479 kinds of hazardous wastes stipulated in the list of hazardous wastes published in 2016 edition in China, which is still a big gap compared with foreign countries. For example, there are 802 kinds of hazardous wastes in Russia, 20 kinds in EU, each of which is divided into 839 kinds according to the production process and the waste and the material composition contained in different process, and 926 kinds in America. There is still much room for improvement in the disposal of hazardous waste in China.

    In recent years, the number of hazardous wastes in China has increased year by year. According to the annual growth of 8%, the number of hazardous wastes will reach 62 million tons in 2020. "In the future, China's hazardous waste treatment industry will work hard on reducing, harmless and resource-based hazardous waste, through technological progress, independently develop hazardous waste treatment technology to meet domestic needs." Sheng Yongning said.

    Promoted by the state's strict environmental protection policy, the price of hazardous waste treatment remains high. The hazardous waste treatment industry has ushered in a "window period" of rapid development, and has become a new hot spot of domestic investment. Some experts believe that with the further opening of the market and the intensification of competition, leading companies with technological and financial advantages will gradually grow further through mergers and acquisitions, the future market value of more than 100 billion enterprises may soon be born, the domestic hazardous waste treatment industry "small scattered" pattern may change.

    Wang Pingfang told reporters that environmental supervision and law enforcement gradually become stricter, greatly increasing the cost of environmental violations in enterprises. At present, the awareness of the importance of environmental protection work by hazardous waste producing enterprises has been continuously improved, and the willingness and initiative of environmental protection investment have been enhanced unprecedentedly.

    Sheng Yongning said that environmental protection listed companies, for example, from 2017 to the end of June this year, 61 cases of mergers and acquisitions, 24 involved new business, nine of which entered the hazardous waste disposal industry.

    Wang Weidong, deputy director of the Condition Guarantee Department of Lanzhou Chemical Research Center, said that hazardous waste treatment enterprises should strengthen their contacts with hazardous waste producers, timely grasp the production and storage of hazardous waste, do a good job of service, and help chemical enterprises solve their worries.
