E-waste refers to electronic products nearing the end of their "useful life." Computers, televisions, VCRs, stereos, copiers and fax machines are common electronic products. Some E-waste contains toxic materials which can cause severe environmental pollution if not properly handled. At the same time, the e-waste can be turned into useful materials after refurbishment and extraction.

Electronic waste is becoming an increasingly pressing problem in China with the surging of the sales of electronics. It is estimated that the country will be producing more than 6 million tonnes of electronic discards in 2020.

The central government has been encouraging recycling and centralized treatment of E-waste. A regulation issued by the State Council, China's Cabinet, has been in place since January 1 to ensure better management of E-waste recycling.
