Machine more than 5 million units
Washing machine
About 500 million units,
Refrigerator
About 400 million units per year of waste household appliances out of more than 1500 million. Discarded appliances such as these can not be effectively harmless, may become harmful to the environment of e-waste.
Home appliances is a new type of "urban mines" of their recycling, resource depletion can effectively relieve the pressure. Discarded appliances contain a large number of precious metals and non-metallic materials, for example, only the copper content in the circuit board had 9% to 30%, also containing gold 80 ~ 1500g / t, Ag 350 ~ 1850g / t, Sn 80 ~ 1500g / t, resin 350kg / t and so on. Discarded appliances on the various raw materials classification and separation, recycling and re-utilization, resource depletion will effectively alleviate the pressure.
Appliance for improving waste recovery and treatment system, China's first "electrical and electronic waste recycling regulations," is expected to be introduced this year, it will be clear that the implementation of producer responsibility recycling of waste home appliances, home appliance maker will scrap appliances responsible for recycling and processing company set up a special fund to subsidize.

Changhong
Engineering Technology Center Dr. Pan Xiaoyong said they Tsinghua University, China Research Institute developed the construction of home appliances discarded
CRT
TV recycling line will be built during the year. In addition to CRT TV recycling line demonstration outside
Air conditioning
, Refrigerators, washing machines, home appliances such as recycling and treatment technology and the production model line has also been included in the next 5 years, Changhong plans. "Only a large scale, can reduce costs; only industrialization, with a reasonable recovery of channels and management mechanism, we can better serve manufacturing services." Dr. Pan wants the state to increase financial input in this regard. At 15 million units / year recycling capacity, and Changhong the recovery of funds required about 1200 million.
Present, because the state has not issued the relevant policies, enterprises mainly through three kinds of way to get used household appliances: First time in the sales of new products for "TM"; two major direct and local recyclers of waste materials Contact the acquisition of waste household appliances; three in-house production waste materials. However, first consider the environmental impact approach to no secondary pollution, the primary prerequisite, therefore the higher cost of processing, by the way of access to used household appliances, can only operate at a loss in the state.
Present, China's national conditions, abandoned appliances in the recovery time must be paid to the consumer must pay. For pricing, market conditions are still under the general completely scrapped the TV about 30 ~ 150; completely abandoned home hang about 300 600 air-conditioned; completely scrapped refrigerator about 50 to 200.
Effective recovery will have a good social benefits. Discarded appliances to the human body contains a large number of environmental harmful substances. To lead as an example, a 21 inch cathode ray tubes contain about 1 kg of lead (leaded glass forms, leaded glass, weighing about 5-8 kilograms), according to five million units of
TV
Scrap volume, China's color TV only to have 5,000 tons of lead pollution. Therefore, recycling waste household appliances, first of all to address these toxic and hazardous substances to the environment and harm the human body, thus effectively alleviate the pressure of environmental pollution.
