Scrap means any substance which is used for recycling after being manufactured for the first time. Recycling of substances is important for many purposes one being is it reduces the overall cost of the product which is made from the recycling process and the other is it affects the economic conditions of the country.
Metal scrap is collected and then melted which later is used to make new products. Scrape can come from any source, it could be metal, non-ferrous, or anything like plastic, metal from broken windows, washing machines, refrigerators, etc. it can be solely of metal or mixed with steel, copper, or any other impurity which could be separated while recycling procedure. Metals are of two types.
- Ferrous metals ( they contain iron)
- Non-ferrous metals (iron is absent)
Both ferrous and non-ferrous have different mechanical and physical properties and it also affects its strength and durability. Ferrous metals have an additional magnetic property. Coins with much economic value are made up of non-ferrous metals. Silver gold is also non-ferrous metal that is used all over the world to make jewelry items. Many metals can be used in the medical field due to their specific properties for example radioactive metals are used in the imaging and radiation therapy techniques used in therapeutics. In the metal industry, many metals are recycled and made into new products and much variety of substances. The metals used for recycling are mostly
- Iron
- Steel
- Tin
- Copper
- Bronze
- Lead
- Brass
- aluminum
Benefits of metal recycling:[i]
The recycling of metals is crucial for maintaining the ecosystem. Not only does the atmosphere affect life on earth but also the other earthly factors like mountains minerals etc are some of the important factors. The industrialization has advanced the quality of life of humans but on the same side, it has effect nature by leaching out its many natural resources including many metals. it’s important to preserve these resources for the long-term sustainability of life. We use many metal objects in our everyday life at home or the workplace. Metals are present from a simple form as a spoon in a home to a gigantic technology as vehicles. It has reduced environmental pollution by 89% leading to the belief that recycling of metals has environmental impacts. Metal scraping has the following major benefits
- Environmental benefits
- Economic benefits
- User benefits
US environmental protection agency has researched according to which metal recycling is beneficial economically and in many other factors, some of them are explained as
- if the recycled metal is being processed the amount of energy required to produce the new product an approximate 82% less energy Is used. approximately 700 kg of coal energy
- If recycled metal is used the raw materials used for manufacturing decrease and the total amount of raw materials lessen up to 95%. Minimally 1120 kg of iron ore is saved.
- Many environmental factors also affect this, for example, it decreases air pollution by 88%
- The mining wastes in the manufacturing process is reduced up to 98%
- Water pollution can also be affected if wrought iron or scrap metals are used instead of virgin iron.
- Almost 90 KG’ of limestone are also saved if already processed metals are used.
- The most important factor is the lesser amount of energy that is demanded if the scrapes are remolded. different metals show different types of percentile of conservation of energy.
Metal Recycled Energy saved
Aluminum (Al) 92%.
Lead (Pb) 60%
Zinc (Zn) 53%
Copper ( Cu) 82%
Where to take scrap metal & Prices:
Most people around the world have no idea about the money value of scrap metal. Scrap metal can be recycled and it can be traded off or sold at any scrap yard in exchange for money.
