The employees of China Baowu Guangdong Shaogang Iron and Steel Co., Ltd. are putting domestic garbage into the corresponding garbage bins (pictured). It is reported that since March this year, the company has set up five intelligent waste recycling devices for domestic garbage in the factory. Each unit produces the recyclable household garbage (such as waste paper, waste plastics, etc.), and scans the QR code on the intelligent recycling device with a mobile phone, and delivers it to the corresponding window as required. The intelligent recycling device automatically identifies and calculates the waste product. After the points have reached a certain value, you can go to the entrusted management unit to exchange shopping items.
