TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Method: Freestanding container is used for collecting and storing waste to be sorted; and the independently-stored waste is independently transported to recycling place. The waste that needs to be independently collected and treated is independently collected and treated based on the set standard and common method and cannot be mixed in the uniformly-treated medical waste. Waste is crushed using full-sealed device, where UV sterilizing lamp is installed for sterilizing air. The crushed waste material is continuously transported to the radiating area by conveying belt. Grading uses mechanical method and comprises magnetic separation using magnetic separation device to separate magnetic material, which can be recycled as raw material for metallurgy; air separation for separating light material including fiber and other organic materials, which are capable of being used as construction composite material after being cleaned and crushed; and gravity jigging for separating heavy material including inorganic minerals and metals such as sandstone, where material includes metals that can be separated by ore dressing, for use as raw material for metallurgy, and the rest material can be used as building material or for land filling.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The first type of material is prepared into solid fuel block, and added with combustion improver, stabilizer, oxidizer, and/or anti-smoke agent. Preferred Component: The combustion improver is potassium nitrate, magnesium nitrate, sodium chloride, sodium nitrate, calcium oxide, potassium permanganate, magnesite, and/or potassium perchlorate. The stabilizer is barium nitrate, magnesium nitrate, calcium oxide, magnesium oxide, and/or sodium carbonate. The oxidizer is peroxide, nitric acid, sodium dioxide, potassium peroxide, zinc nitrate, potassium perchlorate, calcium oxide, calcium nitrate, and/or lithium nitrate.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The adhesive is starch, bentonite, and/or yellow soil.
