All electronic items, such as TV, radio, tape or computer, are always contain gold. But compared to all these devices, cell phone recycling is more attractive. Because the greater amount of gold contained and have smaller physical size so that the collection process more practical. In developed countries, used or damaged electronic equipment become a spesific issue. The service after the warranty period is extremely rare. If any, the cost is very expensive, so it is more practical to buy new.
Therefore, damaged electronic goods was almost no value. Meanwhile, In Indonesia the dead mobile phone still valued around USD 50 thousand, because there are several components that can be use to another damaged phone. The number of phones in use around the world are staggering. The global mobile phone sales increased 12 percent compared with 2007, to 1.28 billion units. In fact, the models and new brands continue to appear, teasing the old phone owners to change and dispose of old mobile phones.
Of these billions of mobile phones, of course there are millions of mobile phone that is broken or removed. If there are only 10 million of the phones are damaged or removed, with an average weight of 100 grams per phone, it can be obtained 1,000 tons of discarded mobile phones can be recycled, a very large number. In Japan, the 128 million inhabitants, the average cell phone use period are for 2 years and 8 months. In Indonesia, although no formal research, many people change their cell phone after about 1 year use. Not surprisingly, brands and new models are always welcome at the market. Ten operators GSM / CDMA which tend to reduce rates further, encouraging the consumption of this phone even faster. Even started many who feel the need to have more than one mobile phone.
Of course, from this outstanding phone – There are approximately 60 million units of mobile phones in circulation in Indonesia today – there are just broken. Value is calculated only stay if there are approximately 10% of damaged and recycled.
More than Gold
Japanese’s companies, Yokohama Metal Co Ltd, has done research and found that one ton of material processed gold mine after, the average yield is only 5 grams of gold. In fact, a ton of used mobile phones can yield 150 grams of gold or more. Besides gold, 1 ton of used mobile phones can also produce 100 kg of copper, 3 kg of silver and other metals. Phone recycling plant in Japan, the Eco-System Recycling Co., produces gold between 199.58 – 299.37 kg per month, whose value ranges from U.S. $ 5.9 million – U.S. $ 8.8 million. Similar results with a small-scale gold mining, with the risk and a smaller capital.
Metal materials that have been extracted is generally used for making electronic circuits on a mobile phone or other electronic devices. Metals in very small amount such as Indium, an important component in the manufacture of flat-screen TV and computer screens. Metals such as antimony and bismuth are also used in many high-tech devices. For recycled materials, other than in the country, some Japanese companies have started importing PCB (circuit board) from Singapore and Indonesia. Japan itself had quite a tight competition from other recycling companies from China.
This recycling process become so attractive because the metal prices in international market continues to rise. Gold was trading at price range of U.S. $ 890 per ounce (1 ounce = 28.35 g), after in March touched the highest price in the history of U.S. $ 1,030.80. Copper and lead also reached its highest price in the market, while the silver price moves above the average. This is the new gold mine that has not been recognized by our industry.
