TMSR Holding Company Limited, through China Sunlong Environmental Technology, Inc, operates Shengrong Environmental Protection Holding Company Limited (the “Company”), which engages in the production and sales of solid waste recycling and comprehensive utilization equipment. 

The Company, formed in 2009 and headquartered in Wuhan, is a high-tech company engaged in the R&D, consulting, transfer of environmental protection technologies, and the manufacture and distribution of environmental protection equipment with a focus on industrial solid waste recycling. We own the most cutting edge technologies of physical magnetic industrial solid wastes recovery and comprehensive utilization. By using our technologies, we can process a variety of solid waste including red mud manganese tailings, waste catalyst, aluminum slag, copper mine tailings, iron mine tailings, molybdenum tailings and others. In contrast with using the traditional chemical recovery method, we will be able to abstract valuable metal material from solid waste without generating any chemical pollution. Furthermore, the residues are processed to manufacture high quality construction materials. As a result, we turn solid waste into valuable industrial material with zero discharge.

We have a strong R&D team and have obtained two US patents and multiple Chinese patents. We received numerous awards from industry organizations and government. For example, the Ministry of Land and Resources of the People’s Republic of China is officially promoting our technologies nationally and the Ministry of Industry and Information Technology of the People’s Republic of China has incorporated our technologies into the official governmental procurement list. Our technologies have been widely recognized by customers and peers. For example, our oil catalyst magnetic separation recovery system is popularly employed in many oil refineries. Our patented technologies have successfully accomplished the comprehensive utilization of carbonate manganese slag which had been an unresolved issue for environmental protection industry for many years.

We are committed to improve the environment while reserving natural resources. We believe that our efforts to raise environmental awareness and our cutting edge technologies will help to create cleaner safer neighborhoods and to improve the social, economical, and environmental well being of our community.
