RECYCLING SCRAP METALS Metals such as copper, steel and iron are some of the materials that can be recycled. However, the effects of recycling have not all been positive. Many honest South Africans are able to make some money by collecting old, scrap metal. They take the copper, iron, steel and aluminium they collect to local recycling centres. These centres check the metal and pay the metal collectors, but the job they do is also good for the environment. Unfortunately, some dishonest South Africans have decided to steal metalto take the recycling centres as an easy way to make money. These thieves steal metal from the fixtures of buildings, such as copper pipes, steel taps, manhole covers and iron beams. Electrical cables are another popular target because they are made from copper. The result is electrical blackouts and other problems. The government has measurements in place to address these problems. ln 2007 in Cape Town, a special task team known as "The Copperheads" was created to fight this kind of thefts. 6.1. ln this case study, people recycle to get money and by recycling they help save the environment by preserving and reusing natural recourses. What negative impacts are there because of recycling in the case study? (1) 6.2. Why is the job that the recyclers do good for the environment? (1) 5lPage
