We strengthen technology and equipment R&D, master leading technologies such as polluted site remediation, farmland remediation, mine remediation and groundwater remediation and are actively promoting the industrialization of advanced applicable technologies. We innovate the polluted site remediation model in order to manage the whole-process polluted site management such as design and planning, hazardous chemical removal and disposal, soil and groundwater remediation and land revitalization to provide meticulous and complete one-stop integrated solutions, by which way safety and environmental risks can be reduced and time, manpower and capital costs can be saved to create maximum value for enterprises. We initiated the Soil and Groundwater Remediation Committee of China Chemical Industry Environmental Protection Association to guide the development of soil remediation in the petrochemical field, which has formed extensive influence in the industry and we are struggling towards a green and sustainable remediation leader.
