What they make from recycled waste: new life for old things – metal
May 6, 2021
Products made from metal or with its use surround us everywhere. This is one of the most popular materials for today, which have found application in absolutely all spheres of human activity. Nevertheless, metals are a nonrenewable resource, their resources are not endless, and metal mining is very expensive and labor-intensive, which today has led to an active search for ways to recycle and reuse metals including the emergence of a service scrap car mississauga.
Advantages of recycling scrap metal In addition, scrap metal recycling is also profitable from a commercial point of view. Mining iron ore takes a huge amount of money and effort, which makes the process quite expensive. Remelting can save a lot on all that, as well as reduce the consumption of energy resources and speed up the process of obtaining the necessary raw materials for industrial needs. After all, the extraction and use of iron ore is a costly process, not only from a financial point of view, but also in terms of time. And raw materials for various industries are needed every day. Also extraction of non-ferrous metals from ore with low content leads to deposits of waste rock in large quantities.
And, of course, recycling scrap metal has a positive effect on the environment. Many metals, when decomposed, release harmful salts that enter the soil, water, and then into the air, according to the water cycle of nature, and some immediately “emit” them into the atmosphere. Not to mention the fact that some metals are radioactive and can take dozens or hundreds of years to decompose. Plus, those areas that are used to store metal waste are “dead” and out of the natural reserve, when they could have been used in agriculture or forestry.
Ferrous metal scrap recycling They are the most common, which is why most businesses are involved in recycling them. Ferrous metals are provided by scrap iron and its alloys, in particular with carbon (iron, ordinary and stainless steel). The most frequent sources of such scrap metal are:
Industrial enterprises of different orientation (metallurgical, machine-building and so on);
Companies involved in the dismantling of buildings and structures, non-working household appliances, obsolete pipes, bathtubs, batteries, discarded vehicles, Military equipment, weapons and ammunition. After the recycling procedure, which consists of several stages, we get a fairly high quality raw material, which can be used again to create:
pipes of different diameters, metalware products, rolled products, Sections and profiles, rebars and steel wire ropes, cast iron products. And also to be used in industry, including in the production of machinery, instruments and vehicles. For example, secondary raw materials are actively used in the production of cars in Europe and it is planned to reach 95% of all required metal for their production. In addition, ferrous scrap metal can also be reused on their own for the manufacture of various things needed in everyday life. For example, a press for pressing berries and fruits, a brazier, a burzhuyka, a summer shower and so on. Here everything is limited only by the imagination of craftsmen.
Recycling nonferrous metal scrap Scientific and technological progress, which is developing by leaps and bounds has led to the widespread use of a variety of non-ferrous metals. If previously used 30, today this number has grown to 70 elements. In this regard, the processing of non-ferrous metal scrap is also in demand. It is obtained mainly from:
cables and wires; Worn out devices, instruments and apparatus; Household utensils (aluminum or tin); brass and bronze products, including plumbing products; machine parts made of non-ferrous metals.
There are also quite a few metals from batteries and accumulators, the collection and recycling of which is developing quite rapidly today. Their resource for the recycling industry is boundless; after all, 500 tons of them are imported to Belarus every year. This figure also speaks volumes of the damage only thrown away batteries can cause to the nature.
Copper, in particular the electrotechnical copper, which is everywhere, takes the lead in recycling volumes. And it can be extracted not only from different products and appliances, but also from radio components. Secondary electrical copper is cheaper because it does not need to be refined and can be used immediately for its intended purpose. However, unrefined secondary copper is also in demand. It is used to make bronze and brass.
Next to copper in terms of the amount of scrap metal that can be recycled is aluminum. Its main feature is that this metal can be recycled almost indefinitely. Approximately three-quarters of all aluminum produced in the 1980s is still being recycled and used today. The energy required for this is ten times less than for the production of primary aluminum, and the amount of irreplaceable losses during its processing is extremely small. Recycled aluminum is used in:
aircraft and car manufacturing, composite panel construction for building cladding, production of profiles and fasteners. It is also used in the production of aluminum cans, which are also recycled in the future. This process requires much less energy than recycling paper or plastic.
In addition, lead is recycled. It is mostly used in batteries and cable casings, and after recycling it is used as metallic lead or compounds. Zinc is also recycled, but it can only be obtained from zinc products.
Precious Metal Scrap Recycling Because of the profitability of such a business, a lot of attention is paid to it, and again the environmental benefits are huge. The main source of scrap precious metals is various equipment, including computer equipment and accessories. They produce gold and silver, platinum and palladium, osmium, ruthenium, iridium, rhodium and others. At the same time, these recycling facilities usually specialize in working with specific waste materials. For example, to obtain precious metals only from computers or printed circuit boards. At the same time the most effective way to get some types of precious metals in “pure” form is chemical. Also one of the types of recycling can be considered buying up silver and gold jewels and making new jewelry out of them.
Recycling different kinds of metals is a profitable solution, both for man and for nature, which allows us to get the things we need for life without causing fatal damage to the environment.
