  • Copper….What happens in the life of copper metal?

    Copper products are hard wearing and last for a long time and will often still function long after they have been superseded by newer modelsThis metal  can be recycled indefinitely as it does not degrade when processed.   Recycling  this scrap metal can reduce emissions and energy output compared to production from virgin materials as well as protect our natural resources.

    Benefits of recycling copper

    The economic and environmental benefits of recycling copper are given below and illustrate the sustainable nature of the metal:

    Environment……During mining and refining (purification) of copper, dust and waste gases such as sulphur dioxide are produced which may have a harmful effect on the environment. Although these harmful effects are minimised by producers (sulphur dioxide is captured and used to make sulphuric acid), with recycling there are little, if any, harmful gases emitted.

    Disposal of copper is often in holes in the ground – this is called landfill.  These holes are rapidly being filled up and, as they become scarcer, landfill becomes a very expensive option for waste disposal (of any material).

    Energy saving ……In order to extract copper from copper ore the energy required is approximately 100GJ/tonne. Recycling  uses much less energy, about 10GJ/tonne, that’s only 10% of the energy needed for extraction. This energy saving leads to the conservation of valuable reserves of oil, gas or coal and reduces the amount of CO2  released into the atmosphere.

    Conservation of copper ore……To date only about 12% of known resources have been mined. However copper ore is a finite resource and it makes sense to conserve ore by recycling.

    Economics……It is cheaper to recycle old copper than to mine and extract new copper. Recycled copper is worth up to 90% of the cost of the original copper. Recycling helps to keep the cost of  products down.

    What Happens When It’s Recycled?

    When copper scrap is first received for recycling, it is inspected and graded. The scrap material is melted and in some cases brought to higher purity while molten. Chemical analysis checks the purity level.   The molten copper is cast into a cake or a block for further processing.

    Copper alloy scrap has to be segregated, kept clean and identified so that the alloying elements and impurity content of each batch are known. Copper alloys are then melted together into batches of known composition, some with virgin material so that the recycled material has the alloy composition desired.

  • Metal Recycling Facts

    To meet the goals of efficient management of limited resources, cost reduction and the reduced use of landfills, recycling has become increasingly important to both society and industry. Our society is accusstomed to hearing the three R’s of recycling (reduce, reuse, recycle) to include paper, plastics, bottles, cans, and cardboard; however, many people do not know that you can recycle metal as well. Recycling metal has many benefits including reducing pollution, saving resources, reducing waste going to landfills and preventing the destruction of habitats from mining new ore.

    “Scrap-recycling facilities are like mines above ground, rich with resources that can be reused to preserve the environment, at a fraction of the cost to mine and refine metals from virgin ores. Scrap metal is not waste or trash. Rather, it is a continuous resource – made from old automobiles, appliances, buildings, bridges, airplanes and more. Scrap metal may, in fact, be one of our most precious resources. Because it can be re-melted and reshaped into new products countless times, scrap metal is a resource that will never be depleted.”

     

    Energy Conservation

    The amount of energy saved when using various recycled metals compared to virgin ore is up to:

    • 92 % for aluminum
    • 90 % for copper
    • 56 % for steel

    According to the U.S. Environmental Protection Agency, when you recycle a single aluminum beverage can, you help conserve enough energy to power a 60-watt light bulb for more than four hours.

     

    Environmental Benefits

    Recycling your metal conserves natural resources by reducing greenhouse gas emissions and using less energy than making metal from virgin ore. New metal production releases a far greater amount of greenhouse gas emissions compared with making products from recycled metal. These emissions may influence climate change along with the possibility of also causing harmful levels of air pollution in cities, which can result in potential respiratory health problems for you and other residents. TheI  Institute of  Scrap Recycling Industries(ISRI) reports that recycling metal may cut greenhouse gas emissions by 300 million to 500 million tons.

    In addition, the use of  scrap metal instead of virgin ore generates 97% less mining waste and uses 40% less water, according to the National Institute of Health.

    An additional bonus is that your environment is clean!

     

    Economic Benefits

    According to the National Institute of Health, the recycling of scrap  metal creates 36 times more jobs than sending the same amount of metal waste to the incinerator, and six times more than sending the metal to a landfill.according to the National Institute of Health. The National Recycling Coalition says the recycling industry in general generates $236 billion annually. More than a million workers across Americaare employed.

  • Featured ImageWhat is the most recycled material on earth?

    That would be…..STEEL!

    Almost 69% of all steel is recycled in North America each year, more than paper, aluminum, plastic and glass combined. North America’s average recycling rate has been in excess of 60% since 1970.   More than 80 million tons of steel are recycled each year in North America.  For every ton of steel that is recycled, 2,500 pounds of iron ore, 1400 pounds of coal, and 120 pounds of limestone are conserved.    There are millions of tons of iron and steel which are diverted from the waste stream to the recycling stream due to steel’s magnetic properties that make it the easiest material to separate from the solid waste stream.

     

    Did You Know?  Metals can  be recycled indefinitely without ever losing their properties!

     

    Steel is unique among materials. In addition to an attractive mix of strength, quality, cost competitiveness, and adaptability,it  is uniquely recyclable.   It is a widely used magnetic metal.  Steel cans are 99 percent steel with a thin coating of tin, though they are often called “tin   cans.” Steel is made from iron ore, and is 100% recyclable. In fact, all steel  products are made with recycled metal, making it the most recycled material in   the world!

     

    Steel plays a major role in almost every aspect of our daily lives.  The list of steel uses is long and impressive: bridges, tools, buildings, clothing and countless other items all utilize steel in one form or another.  The average  anadian owns over 900kg (2000 lbs.) of steel included in a wide array of goods

    • Products such as cans, the outsides of many appliances, and  car fenders are made with about 30% recycled steel in a basic oxygen furnace.
    • Other steel products such as steel beams and reinforcement  bars used to support cement are made in an electric arc furnace with around   95-100% recycled steel.

    When you buy steel, you’re almost always buying recycled.

     

    Fast Fact: By recycling, the  steel industry saves a lot of energy -……..enough to power 18 million households for  a whole year!
