How to Sort Scrap Metal

Scrap Metals is generated by the disposal of items that are no longer serviceable or wanted. They are not biodegradable, therefore are well suitable for recycling. However, how to sort them for recycling is still a problem for many people.

The most important circle of sorting scrap metal is to separate ferrous meal from non-ferrous metal. It can be difficult to identify and sort scrap metal since some of them look the same. This is why we should always have a magnet! A magnet will be your good helper in identifying ferrous and non-ferrous metals. Ferrous metal is magnetic, including iron, steel and others; non-ferrous metal are all not magnetic like aluminum, copper and brass. You can put the first into one pile and latter into another pile.

Now let’s go to non-ferrous pile first.Copper, aluminum,brass, gold are all the valuable recyclable materials. Copper is lightweight and reddish in color. It may become greenish over time due to corrosion. In recycling process, it can be classified into three kinds:

Electrical wires. Some metal recyclers accept wire with the insulation on yet at a much lower price compared with wires which has been removed insulation by cable granulator.

Copper tubing. You also had better remove any brass fittings from the tubing, or scrap recycling companies likely offer you a lower price because of labor cost of removing the brass by them.
 

Copper tanks such as special and water heater tanks. These tanks are considered heavy copper and should be removed any attached insulation, covers and fittings.

Aluminum is a lightweight metal with a dull silver color. Sosa cans,lightweight lawn furniture and aluminum wire are considered light aluminum while all other aluminum is considered heavy aluminum. Aluminum wire can be stripped by wire stripping machine. Pure aluminum wire will be given higher price.

Then, let’s come to the pile of ferrous metal. Tin, lead and steel are the main kinds of ferrous metal.Steel is a very solid and strong material that normally will be rust colored if weathed. Lead item will be dark gray in color. Lead is often used for piping, scuba diving weights and fishing plumbs. If you have lead batteries , please put them in another pile as well. Car batteries are a good example. Tin can be bent and will make a cracking sound as you bend it. You can make classification of them according to these characteristics. 

How to Recycle Radiator Scrap?

How to Recycle Radiator Scrap

Radiator is widely used in cars, trucks and other automobiles. Radiators were also once an essential part of a home heating system. In today’ s life, AC radiator is more known by commons. Before discussing how to recycle radiator, let’s have a general knowledge of this three kinds of radiators.

Radiator in older cars were likely made of brass or copper. In newer cars, radiators are typically constructed out of aluminum which is lighter and less expensive. Radiators also have headers or tanks at each end to hold the coolant. These can be made of brass, aluminum or plastic.

Unlike a car radiator, heating radiator is used in your home for heating.It appeared in mid-1980s and fell out of use in the mid-1900s. This kind radiator is always made of cast iron.

The present air conditioner is usually made of compressor, radiator, throttle and evaporator. Gas and fluid are exchanged in radiator, at the same time, the pressure and temperature change. Without radiator, it can’t cool and warm the house. Now radiator is usually made of copper tube and aluminum foil. Both of them have great recyclable value.

Now let’s say how to recycle them. Unless you work on cars yourself, you won’t have chance to see radiator and do not really want to. The best way for you to recycle your radiator is to let your mechanic remove it and recycle it, or recycle your entire car. Radiator in your home should also be recycled at a scrap metal yard.

The recycling of AC radiator is a little complex since the copper tube is covered by aluminum foil. To recycle it, we can use radiator copper&aluminum stripper. Amisy radiator recycling machine can strip the radiator whose copper tube center distance is 19 mm, 21 mm and 25 mm. The scrap radiator fin should be put into the inlet smoothly and the stripped copper pipes and aluminum foil can be discharged automatically. After being separated, the copper tube will keep complete and the aluminum foil will become irregular pieces.

E-waste Recycling in Australia

Electronic waste is one of the fastest growing contributors to Australia’s waste stream. As more and more outdated electronic equipment ends up in landfill, the negative impacts of e-waste on the environment and humans will increase.

Electronic waste can come in many forms including computers, photocopiers, printers, faxes, monitors, batteries and mobile phones.



According to public data on internet, in 2008, there has been an estimated 37 million computers in Australia that were already in landfill or sent to landfill. With over 3 million computers being sold every year, 75% of them will end up in landfill. In 2007/8 16.8 million computers reached their end of life. Of this, only 9% will be recycled. In the following years, this problem will be more serious. Besides, 17 million televisions were either in landfill or sent to landfill in 2008.The growing e-waste continues to be a troublesome problem for the environment.

Some of these items can be highly toxic and environmentally damaging. The following harmful substances can be found in everyday e-waste.

• Lead in cathode ray tubes and solder
• Mercury in switches and housing 
• Arsenic in cathode ray tubes
• Antimony trioxide as flame retardant 
• Selenium in circuit boards
• Cadmium in semiconductors
• Cobalt in steel for magnets

When e-waste is sent to landfill, poisonous substances can leach from decomposing water into the environment.So how to recycle and reuse these e-waste is a pressing problem for Australia. E-waste like telephone wires, household cables, AC radiator are not difficult to recycle. With a copper cable granulator or AC radiator recycling machine, you can easily turn waste into profit.
