A non-renewable resource (also called a finite resource) is a resource of economic value that cannot be readily replaced by natural means at a quick enough pace to keep up with consumption. An example is carbon-based fossil fuel. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas. Earth minerals and metal ores, fossil fuels (coal, petroleum, natural gas) and groundwater in certain aquifers are all considered non-renewable resources, though individual elements are always conserved (except in nuclear reactions).

The high-performance ultra-lightweight foam ceramic comprises the following chemical components in percentage by weight: 50%-70% of SiO2, 10%-20% of Al2O3, 3%-8% of CaO plus MgO, 5%-10% of Fe2O3, 1.0%-6.0% of K2O plus Na2O and 1.0%-2.0% of ZrO2 plus SiC plus C, and the process flow comprises the following steps of preparing materials, performing fine crushing, granulating, loading into an assembled refractory castable kiln tool, striking off, placing into a kiln for firing, getting a product, cutting into the product in the required specification and the size, inspecting, packaging and putting into a warehouse. According to the high-performance ultra-lightweight foam ceramic disclosed by the invention, the defects that the expansion of cracks in the past can affect the product quality, the rupture strength and the compressive strength are not sufficient, the resistance to thermal shock damages is poor and the like, can be solved. According to the high-performance ultra-lightweight foam ceramic disclosed by the invention, compressive stress is generated in a main crack action region for preventing the expansion of the cracks, so that the toughening effect is shown; and by introducing dispersed zirconium oxide particles, the rupture strength and the compressive strength of a composite can be obviously improved, the resistance to the thermal shock damages of the material is also improved, and the optimization of non-renewable resources is further utilized.

Integrated big data management system for urban renewable resources
The invention relates to the field of garbage classification, to an integrated big data management system for urban renewable resources. The system comprises a system platform, a user terminal, a recycling terminal and an intelligent weighing device. The user terminal sends order information edited by a data editing unit and an order address obtained by a GPS positioning unit to the system platform. The system platform screens appropriate recycling terminal information based on the order address and distributes the order information and the order address to the qualified recycling terminal; after the recycling terminal confirms the acceptance of the dispatched information, a staff member arrives at the order address by carrying the intelligent weighing device within the specified period; and after identifying user information, the intelligent weighing device obtains actual order information and sends the information to the system platform. On the basis of combination of the GIS geographic information technology, the mobile data communication technology and the GPS positioning technology, full-course dynamic management of garbage classification is realized according to the modern Internet mainstream software technology.
