Unit 3 Inventors and inventions一、閱讀理解A new “smart bin” could mean the end of environment-conscious families spending hours sorting tins, cartons, bottles, and cardboard for recycling.The invention, which can help sort rubbish into recycling categories without needing people to operate. It is being trialed in Poland and is set to go on sale in UK within a few years.The bin, designed by start-up pany Bin.E, recognizes different type of waste via a system positioned inside the bin which uses sensors, image recognition and artificial intelligence. Once waste is placed inside, the camera and sensor identify its type and place it in one of the smaller bins. Then it presses the waste so it occupies less space.It is thought that the bin could be stocked by department stores such as John Lewis, which said it is introducing more new hi-tech recycling bins. Matt Thomas, a buyer at John Lewis, gave us the reason, “Weve recently seen a jump in specialist bins sales, with a 25 percent increase in the last few months alone. We have noticed our customers are being more and more focused on sustainability. In response to this demand, we are really excited to introduce a smart bin this autumn/winter season-designed to make recycling more efficient and functional for the everyday home."Bin. Es official release on the market will take place in 2018. However, at first only a larger version designed for offices will be available. The office bin will sell at 430 while customers will need to pay a 107 subscription fee for an acpanying smartphone app, which hooks them up with collection services. A spokesman at Bin. E said that home version of the bin will be cheaper and will not include a monthly payment.They added: “After the office version, we plan to create an outdoor version and later the home version. We decided to go for the outdoor version for public areas first because it is more difficult to organize an efficient waste segregating system than in our homes.”1.What do we know about about a new “smart bin” from the first paragraph?A.
