The deposition of home appliances increases with the rising population in Hong Kong. There are approximately over 70,000 tonnes of computers and electrical appliances abandoned every year. These items include televisions, refrigerators, washing machines, AV equipments, microwaves, electrical fans, electric kettles, cookers, air-conditioners, heaters, electronic game players, etc., which contain abundant recyclable/reusable parts and substances like metal and plastic. Recycling these scrap products is a good way to reduce disposal of waste and achieve recycling and reuse of resources.
