The rapid development of technology leads to frequent personal turnover¹ of mobile phones. About 50 percent of users in China change to a new phone every 18 months, according to Chinanews.

技术快速发展导致个人手机更新迭代愈发频繁。据中新网报道，约50%的用户每18 个月就会换部新手机。

 

However, alongside the high replacement² rate is a low recycling rate. China now has about one billion unused mobile phones, but only two percent have been recycled with most of the rejected devices improperly³ handled.

然而，伴随高迭代率的是低回收率。国内现在有约10亿部废旧手机的存量，回收率只有2%左右，大量更换下来的旧手机都没有得到妥善处理。

 

“废旧手机”指被废弃的、老旧的手机，所以英文可以用old and discarded cellphones表示，也可简称为discarded phones。
