【題目】 Did you know that almost 100% of the materials in your mobile phone can be recovered and recycled to generate energy or make new products, such as plastic products, electronics or even jewelry? Every mobile phone contains significant amounts of copper, aluminum, gold, plastic and other non-metals that can be recycled and reused.

The Singtel x SingPost E-waste Recycling Programme, launched on World Environment Day, 5 June 2017, is a cooperation between the two leading ICT and postal companies as part of their environmental sustainability efforts.

Called ReCYCLE, the programme provides the means for people to do their part for the environment by recycling their mobile and internet related electronic waste such as mobile phones and chargers, laptops and tablets, modems and routers, and other related accessories(配件).

These unwanted devices can be dropped off into the ReCYCLE bins at selected Singtel Shop and Singtel Exclusive Retailer outlets and Post Offices. You can also ask for a ReCYCLE envelope from any Singtel Shop and Singtel Exclusive Retailer outlets, and Post Offices, and mail your mobile device and accessories at no charge.

This programme reduces waste as it ensures that the valuable metals and components the devices contain get recovered. However, e-waste that is often thrown away, including all the precious metals that it contains, will be burnt and landfilled at Semakau Landfill.
