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.
Is the data in my e-waste safe when sent for recycling?
We assured that all storage media devices like SIM cards, memory cards, USB flash drives and hard drives are safe for recycling. Cimelia, our e-waste recycling partner is a reliable and NEA-licensed company, which are only interested in extracting(提取) the precious metals from the devices, NOT the data in them. The devices will go through a crushing process for secure destruction after the whole extraction process.

It covers all the aspects of language learning, including vocabulary, translation, grammar, spellings, spoken and reading skills.

Picture the scene: the battery on your mobile phone has run out. You can't make any calls for help and no one can contact you. You are all alone - well, not quite. Just reach into your pocket and take out a piece of sugar.Put it into the battery, wait a minute, and you're back on the phone.
Thanks to a couple of American scientists, this situation could become real.Swadesh Chaudhuri and Derek Lovely have invented the"bacteria battery" - powered by bacteria that eats sugar and turns it into electricity.
"This is a special organism," Lovely said."You can harvest enough electricity to power a cell phone battery for about four days from a spoonful of sugar."
In the past, bacteria batteries have been expensive and not long-lasting. But this battery uses more efficient bacteria that can turn 80 percent of sugar into electrical energy. This is 30 percent more than similar batteries can manage.
The bacteria battery could become as small as a household battery. It's also cheap and stable, as sugar can be taken from waste and crops.
But the sugar to electricity process is slow: it could take weeks for the bacteria to digest a cup of sugar.And it produces "greenhouse" gases which pollute the environment.
The scientists understand there is a lot more work to be done. "It is still young," said Lovely."Where we are now is where solar power was 200r 30 years ago."
But he believes the battery could be used in scientific equipment at the bottom of the ocean.Other ideas include using sugar in the blood to run medical devices in the human body, and taking sugar from animal waste to provide energy to power homes in rural areas.
1.This passage is mainly about_ .
A. how to change sugar into electricity
B. a scientific invention of a new kind of bacteria battery
C. a new way to reduce pollution caused by mobile phones
D. a new kind of mobile phones and its future
2.Which of the following is not the strong point of the newly-developed battery?
A. Convenient. B.Stable. C. Inexpensive. D. Quick.
3.The underlined sentence in the 7th paragraph actually means .
A. the bacteria battery shares some similarities with solar energy
B. scientists will continue their work until they find solar power
C. there is much room for the improvement of the bacteria battery
D. the bacteria battery will get popular in 20 0r 30 years
4.According to the passage, who will find the bacteria battery less useful?
A. Farmers. B. Divers. C. Doctors. D. Electricians.
