Da Xing Recycling of waste materials recycling _ _ Shenzhen gilded gilded Recycling scrap materials provided by the Da Xing. We are Dongguan City of scrap material recycling companies (www.dxhphs.com) located at: Dongguan specializes in: scrap metal recycling, waste plastic recycling, e-waste recycling, industrial waste recycling, building methanol come from? Dai Lixin told reporters that carbon dioxide can be achieved together with hydrogen: carbon dioxide emissions from power plants a lot, but think of hydrogen from the environmental point of view, the best able to use wind power, solar energy and other renewable power from the system, so "Methanol-based" power to become more green a. Obtain "green" methanol is not simple, because the reaction conditions are very harsh. Ding Kuiling research group is trying to research, and has achieved industry recognition effect. Another research group responsible HAN Zhao Bin told reporters, the more gentle reaction, methanol made more "green", the less due to energy consumption. In the future, the use in industrial practice, they will think gas, waste heat recovery, to minimize energy consumption. "Pollution" mechanism to deepen discussions recently, reporters from China's largest third-generation synchrotron radiation equipment - Shanghai source noted that nearly two-year project on environmental research requests keep adding gilded recovery, the current total to reach 837, hitting the 100 number of research institutes. Shanghai Light Source is currently one of the world's most advanced equipment, "microscope", to use it, scientists can research through simulation experiments clearly know how air pollutants eventually forming, how dispersed. From environmental hazards, the composition of newspaper used computers, only monitors and circuit boards, recycling disposal requires high technology, improper recycling will cause environmental pollution. However, because 90% of copper, aluminum, steel, plastic or the like representing the computer. Recycling of these materials recovered gold plating, and if the sorting is to manually disassemble, Shenzhen gold plating process does not involve chemical recycling, not only does not cause environmental pollution, and high recovery rate. Referring to the practice in developed countries, the best option is to scrap computer to computer recycling center. Follow the "first use, and then dismantling" principle, namely, first to maintain the basic functions of an old computer, you can by inspection, cleaning, maintenance, etc. simply put it into a secondary consumption, that can not be directly used, and can be disassembled recovery of value in a variety of electronic components, and finally take the mechanical, physical, chemical raw materials recycling methods. That is recovered first level is reused whole or parts; second level is not split, plastic, metal, glass categorized by parts; finally melting.
