In North America, the most common material recycled is Steel. Counting back to more than 150 years ago the steel industry has recycled such materials on a daily basis in mass quantities due to the economical advantages. Since recycling is far more economically smart than paying workers to mine the iron ore and go through the procedures of production to form new steel which is no better than recycled. This is because while recycling no physical properties are lost during the process and requires far less energy and materials than if we were to refine from iron ore into new steel. The annual consumption of energy has been reduced by more around 75% each year due to the recycling of steel. To understand how much energy this is, nearly eighteen million homes could be powered for one whole year. In 2005 alone over 76 million tons of steel was recycled. For each ton of recycled steel, 630k kilograms of coal, 55kg of limestone, and 1,100kg of iron ore is saved.
In the past years, about 75% of all produced steel has been recycled. Most industrial steel such as structural plates and beams are recycled 97.5% of the time in 2004 and 2005. For other varieties of steel elements like reinforcement bars the recycling rate is a bit lower at 65%. Due to this high recycle rate most structured steel usually contains about 95% recycled content. Lighter, flat rolled steel only contains roughly 30% recycled materials. Since steel beams are made to be a standard dimension, a small amount of waste is produced while in construction. The little amount that is produced during construction can be recycled. Steel has advantages over wood in many ways. A few are stability, quality, and for economic reasons. A normal 2000 square-foot two-level house would use about five to six recycled cars for its steel frame. On the other hand using wood can require up to if not more than 40-50 trees.
Each year the demand for steel strengthens. There is a fair amount of steel that exists today and most is actively used daily. However, recycled steel has to be augmented by a "first-use" metal, extracted from raw materials. Automobiles, cans, appliances are a few of the more common steels recycled daily. Typical automobiles are roughly 66% iron and steel and appliances are a smaller amount lower at 65% steel by weight. Recycling the steel usually happens through the interlaced steel mills and the standard oxygen routine. Most steel is normally electrically melted by a furnace or for high alloyed products a furnace for induction is used.
How To Recycle Tires
Throughout history, people have been recycling waste materials in some way or another. The main reason that recycled materials were used, rather than new was that second hand material was cheaper to use. Today, we have other reasons for recycling our waste materials, such as preserving our planet, reducing waste materials being buried in the earth in landfill sites, and saving money by using second hand materials, rather than producing new materials.
The first real recycling started out in pre-industrial times when scraps from precious metals were recycled, and melted down for further use. Around this time, Britain was also recycling ash, and dust as the base materials used for brick making. In 1921, Britain also began a waste paper association, which was created to encourage the recycling of used paper. Another example of early recycling was that during the world wars when the governments encouraged citizens to recycle by donating their metals, and conserving fiber to do their part for the wartime effort.
Recycling And its Benefits
Recycling has two main benefits, which are reduction of both energy, and virgin materials needing to be collected, as well as reducing the amount of waste that is disposed of in landfills. Recycling also reduces the negative impact that waste has on the environment, and reduces the space needed to keep refuse sites functioning, it is estimated that in the UK, by the year 2010, almost all of the landfill sites will be full.
By recycling, we are not only helping our planet, we are decreasing the money spent on raw materials, and their production. Currently, the UK is recycling around 17% of their waste, which is a small amount considering that some neighboring countries are recycling up to half of their waste, that would ordinarily end up in a landfill site.
What Are The Recyclable Materials
For recycling to really work, households must be made aware of what is a recyclable. Many people are still throwing materials that could be recycled into their regular rubbish bins. Some of the materials that can be used for recycling are:
- Asbestos,
- Batteries,
- Building Materials,
- Cars,
- Clothing, and material,
- Compost matter,
- Computers,
- Electrical equipment,
- Furniture,
- Glass,
- Metals,
- Mobile phones,
- Paint, and oils,
- Paper,
- Plastic,
- Printer cartridges,
- Wood
Criticism Of Recycling
Recycling is a great thing, and has a positive impact on our long-term economy, living standards, and health of the planet we live in, although there are some factors surrounding recycling that are not ideal. All recycling uses energy of some type whether it is fuel for transportation of the materials, or the processing that takes place to reuse the materials. Additionally, many recycling plants use large amounts of water while preparing, or cleaning the materials they will reuse.
The only way to really benefit from recycling, and reducing the waste that is being produced is to use fewer materials where possible, and reuse materials in their current form.
