TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Method: The waste to be sorted is collected and deposited independently in container and transported to the recovery processing place independently. Waste is independently collected and processed according to pertinent regulations and conventional method, where the integrally processed medical waste is not mixed. The wastes are crushed in totally enclosed device, where sterilizing air with UV Sterilamp(RTM: germicidal lamp) is provided inside the totally enclosed device. Sorting comprises magnetic separation using magnetic separation device for separating magnetic material, which can be recycled and used as metallurgy raw material; air separation for separating lighter material mainly containing fiber and other organic material, which can be used as building composite material after cleaning and crushing; and weight jigging method for separating heavier material mainly containing metal and mineral material like sandstone, and material with high metal content, which can be used as metallurgy raw material, where other material is used as building material or used for land fill disposal. The fourth kind of material is pressed into blocks for the next burning step.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: Combustion improver, stabilizing agent, oxidizer, and/or anti-smoke agent are added while preparing the first kind of material into block fuel. Preferred Component: The combustion improver comprises nitrate, magnesium nitrate, sodium chloride, potassium permanganate, sideroplesite, and/or potassium perchlorate. The stabilizing agent comprises barium nitrate, magnesium nitrate, calcium oxide, magnesia, and/or sodium carbonate. The oxidizer comprises peroxide, nitric acid, sodium dioxide, potassium peroxide, and/or magnesium peroxide. The anti-smoke agent comprises sodium hydroxide, potassium hydroxide, zinc nitrate, potassium perchlorate, calcium oxide, calcium nitrate, and/or lithium nitrate.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The adhesive comprises starch, swelling soil, and/or loess.
