Steel Recycling Process and its Impact on the Environment

Steel recycling reduces energy consumption for manufacturing processes and prevents harmful gas emissions in the environment.

FREMONT, CA: While all types of steel are recyclable, the recycling procedure for each type of steel may differ from that of many other materials. Steel items will be sold to a scrap yard for compensation rather than being transported to a landfill or regular recycling center because of their intrinsic value.

There are three types of steel scraps that can be sold to scrap yards:

Industrial scrap

Product manufacturing in fields like automobiles and appliances results in prompt scrap. Excess steel from these warehouses and companies is sold to scrap purchasers at a high price.

Home scrap

Steel scrap generated in-house in steel mills during the production of steel is referred to as home scrap. Steel trimmings and rejected scraps are included in this category. It is frequently redirected back into the furnace, so it does not need to be collected or purchased.

Obsolete scrap

Obsolete scrap refers to the remainder of steel waste, including items such as individual household appliances, junked autos, office waste, and residential waste. This category can also include ancient junked constructions or buildings that are taken to a junkyard and salvaged for their steel components.

Steel scrap is sorted and shipped to mills or foundries after being collected by scrappers in person, at designated drop-offs, or at buy-back facilities. Excess steel scrap is then melted down in a furnace that reaches approximately 3,000 degrees Fahrenheit and cleaned to remove impurities. The melted steel is then hardened into sheets and ready for transport. After that, the newly recycled metal is ready to be delivered to various manufacturers for use as raw material, and the cycle begins all over again.

Impact of steel recycling on the environment

Steel has a very high recycling rate, both in terms of the steel itself and byproducts employed in the manufacturing process. Each year, about 69 percent of steel in the United States is recycled, and this ratio rises when looking at individual steel products. Steel from automobiles, for example, is recycled at a rate of 95 percent, whereas appliances are recycled at a rate of 70 percent.

Steel recycling can reduce up to 74 percent of energy consumption in production from raw materials. Steel recycling can also help save natural resources and reduce greenhouse gas emissions.
