Because of the lag of soil pollution, and there are many difficulties in the identification and monitoring of soil pollutants in the past, the problem of land pollution has been paid less attention in the past. The relocation and abandonment of industrial enterprises is the product of accelerated urbanization in China in recent years. The relocation of polluting enterprises has been vigorously implemented in various large and medium-sized cities, such as Beijing, Tianjin, northeast old industrial bases, the Yangtze River Delta and the Pearl River Delta.
The environmental problem of contaminated land has become an obstacle in the process of land redevelopment. At present, some old industrial districts located in cities cannot be redeveloped due to pollution problems, so they are very concerned by governments and enterprises in recent years.
Based on the strong support of national policies, soil remediation industry is gradually emerging. According to the data released by the foresight Industry Research Institute, in September 2013, the number of domestic enterprises engaged in soil remediation reached more than 300. In 2014, there were about 500 enterprises in the soil remediation market and up to more than 1000 in 2016.
At present, the most popular soil remediation in China is the remediation of contaminated sites. Because of the expansion of the urban area, the former industrial and mining enterprises have gradually become urban construction land, but the pollution left over by the industrial and mining enterprises is urgent to be harnessing, and the site restoration has become the focus of the industry. The market of arable land restoration began to grow as the importance of ensuring the quantity of arable land, and improving the quality of cultivated land was gradually implemented.
In the soil remediation enterprises, almighty enterprises can carry out pollution site investigation, risk assessment, repair construction and so on. Business basically covers the various links of soil remediation, and has a more competitive advantage. It has become the biggest beneficiary of the development of the industry.
From the statistical data of the prospective Industrial Research Institute, we can see that the net profit of the main listed companies in Chinese soil remediation is above 20 million yuan, and there is a rising trend. It can be seen that the growth of the industry is better.
