Li Huizi, a hardcore gadget lover, has tried to restrain her desire for the latest cellphone after finding a mountain of old models forgotten in a corner of her home.
The 28-year-old resident of Ji'nan, capital of East China's Shandong Province, boasts an impressive collection of unused gadgets, including cellphones, tablet computers, digital cameras, memory sticks, MP3 and MP4 players, as well as their chargers and batteries.
"I didn't want to sell them too cheaply to peddlers who collect the waste, but they were not presentable gifts either. So I just ignored them," said Li, who works for a large State-owned company.
Li is one of China's increasingly affluent middle-class consumers, who are keen to upgrade their electronics but lack knowledge of how to properly handle old products that contain potentially dangerous metals.
The end-of-life goods often escape safe handling as their owners let them collect dust at home, sell them to unlicensed collectors or simply discard inexpensive accessories such as batteries.
Recycling and disposal of small electronic goods has become a growing headache for China. Experts and business owners say the problem is in part due to the absence of government support, though subsidy programs are in place for the recycling of bigger electronic items, such as TVs and refrigerators.
Unseen hazard
Earlier this month, Chinese Premier
Li Keqiang "declared war" on the pollution of water, soil and air in his first government work report at the annual session of the National People's Congress.
While the public applauded the premier's gesture, many have no idea that their cool gadgets can also be polluters.
Lithium batteries for cellphones, laptops and other electronic goods contain heavy metals like cobalt, nickel and copper, which can have negative environmental and health effects if the e-trash is dumped carelessly, said Xu Chongqing, a researcher with the Energy Institute of the Shandong Academy of Sciences.
The heavy metals, which do not break down over time, can contaminate underground water, Xu said, noting that the substances, when accumulated in the human body, may trigger blood diseases and renal failure.
Although there is no precise data for how many small electronic goods reach the end of their lives every year in China, a 2013 report issued by the Solving the E-Waste Problem Initiative, a partnership of UN organizations, industry, governments, nongovernment and science organizations, showed that China put the highest volume of electrical and electronic equipment on the market in 2012 with 11.1 million tons, followed by the US at 10 million tons.
According to the report, the US generated the largest volume of e-waste in 2012 at 9.4 million tons, while China generated the second-highest amount of 7.3 million tons.
However, end-of-life gadgets can be valuable if recycled and technologies are mature, Xu said.
"For example, the content of cobalt in the battery is 15 percent, far higher than the 3.7 percent in the ore," he said.
In addition, precious metals such as gold, silver, palladium and tin can be extracted from the circuit boards of cellphones.
Stumbling block
Recycling companies are not blind to the economic potential of recycling small electronics, but they complain that the business is not cost-effective without government subsidies.
Since July 2012, the government has begun to collect funds from manufacturers and importers of TV sets, refrigerators, washing machines, air conditioners and computers to subsidize licensed recycling companies. However, disposal of small electronic items is not included in the subsidy program.
"In terms of small gadgets, without government support we can't compete with the unlicensed waste collectors. They use primitive but low-cost dismantling and disposal methods," said a manager with Shandong Zhonglv Eco-Recycle Co, based in Shandong's Linyi.
The investment and operation costs for qualified recyclers are too high to be covered by yields if they cannot collect enough small gadgets, according to Xu.
In China, waste electronic goods collection has grown into a full-fledged underground economy.
Small businesses that lack sophisticated infrastructure and expertise strip down the goods to recover components for second-hand equipment or to harvest valuable metals and raw materials.
They often soak circuit boards, a major polluter, in strong acid that can contaminate the air and water, said the manager, requesting anonymity.
"From my observation, many peddlers just dump the leftovers after salvaging useful parts," said Wang Kun, who works at a large technology store in Ji'nan.
Solutions
Recyclers' calls for government support of small electronics disposal have been heard, and the
National Development and Reform Commission is considering adding cellphones, batteries, printers, copiers, scanners and fluorescent lamps to the government subsidy program for recycling and safe disposal.
The draft proposal was made public in December 2013 by the commission to solicit opinions for one month.
In addition to motivating licensed recycling companies with funds, Xu suggested retailers offer "old-for-new" services to stimulate recovery of small electronic goods.
Consumers could also help with better recycling, said Zhang Ning, a Chinese-Australian who makes regular business trips to Ji'nan.
"In China, you can hardly find a formal channel to hand in redundant electronic items," she said, suggesting the government place bins exclusively for disposal of small gadgets, as has been done in some developed countries such as Australia and Germany.
