Recycling Electronics

Electronic devices such as mobiles phones, tablets, PCs are being increasingly discarded used on a daily basis. These electronics contain considerable amounts of metal in them. When these electronics are no longer in use, they can be recycled in order to reduce the landfills and toxic wastes. There are a number of valuable metals found in these electronics.

 The electronic waste is a rich source of precious metals such as gold that can be extracted from computers. Other precious metals that can be recovered also include silver that can be extracted from the electronics. Recovering these precious metals is not an easy task. Some of the modern recycling facilities can recover up to 95 percent of gold whereas facilities in developing countries can recover only up to 50 percent of the metal.

The metallic and non-metallic content from the electronics can be removed using magnets. Apart from gold and silver, metals like aluminum, copper, and brass are also present in the devices. The current recycling rates for electronics are quite low. Not all devices reach the recycling center. An even the ones that do, not all of its metallic content is recovered. The recycling rates can be increased by encouraging the public to recycle their used electronics and having recycling policies in companies.

Scrap Metal Shavings

Metal shavings are a common waste in any metal processing industry. Every day, several metal shavings, chips and fillings are formed during the metal manufacturing processes. A large generation of scrap is created by industrial metal drilling and grinding. These by-products can be sold at a reasonable price to an industrial metal recycling centre. 

Recycling Scrap Metal Shavings

Collecting scrap metal shavings can be quite a task but there are industrial inventions to make it easier. Some commercial machine plants use metal chip vacuums that are capable of handling the sharp edges of the debris.

Recycling of metal shavings is not easy. Longer shavings tend to get entangled during the machining process. Using crushers, the entangled shaving nests are crushed into metal chips which can be transported easily. Metal shavings are also easier to melt down and can be pressed into small pellets. Using the metal briquetting system, the metal can be separated from any coolants or lubricants placed mixed with the metal.

Recycling metal shavings rather than discarding it into the landfills has environmental and financial benefits. It reduces the contamination with tramp oil and also reduces the amount of ore mining required to produce new metal. The scrap value is also a net gain apart from the costs handled for its handling and transportation.
