According to “the project of white paper for circular technology and development for circular science”, there were several points which included complicated resource, unknown source, and hard to classify should be solved in recent market. So, government need to make inventory of breakpoint for resources recycling. For integrating the circular information of the inorganic resources, this project had completed the function of platform for the analyzing of inorganic resources recycling and management system, structure and content of system, mode of operation and maintenance and plan for yearly execution. It also had completed the inventory of basic characteristic of inorganic resources, market price, national standards （CNS） and construction specifications in engineering use, and carbon emission factor to set up basic database for improving the efficiency of resource recycling. For improving the inorganic recycled materials in right place and using, this project also provided information on inorganic resource competition phenomena, future trends and response strategies and analyzed construction costs and economic benefits. In order to enhance the confidence of engineering units in using inorganic resources, this project had drafted the certification mechanism of inorganic resource to ensure the stable quality of inorganic resources and make engineering units happy to use inorganic resources. In response to the blueprint of path for net-zero emission in 2050, this project provided the results of assessment for the carbon reduction in 2 important inorganic resources which corresponding to engineering uses, and analyzed the " Regulations for Greenhouse Gas Offset Projects " to submit a feasible way for greenhouse gas emission credit offset project to promote enterprises participating in the recycling of inorganic recycled materials and reducing greenhouse gas emissions.
