4.1 Stainless Steel The stainless steel production process has very little run off. Therefore, it is said to not have pollute our land and water bodies. Hence making the run off very sterile. In addition, carbon footprint, emissions and energy consumptions of the stainless steel manufacturing process plant has been reduced remarkably with the aid of the enormously high amount of stainless steel being recycled along with the cutting-edge improvements being made in the stainless steel production process. Moreover, the need for the mining of the major resources that are required to make stainless steel such as nickel or molybdenum ore is reduced greatly. This is because stainless steel being recycled on a huge and regular basis. Therefore, the pollution and physical damage caused from the mining of these primary resources can be kept at a minimum since the need for it has been reduced. Unfortunately, the manufacturing process of stainless steel creates massive quantity of dusts. The metals settling out of these emission causes the soil contamination and dust emissions. Filters were used to reduce the dust emissions to the environment. Metals were recovered in the dust filtered and it was re-used in the production process. (Tivnann, 2009) The impact on the landfill disposal of stainless steel has been considerably been reduced as a result of high levels of recycling. Furthermore, due to its anti-corrosion properties, stainless steel does not need to be cleaned on a regular basis. Therefore, there will be lesser run off of cleaning products and detergents into the water bodies. According to Anon., (2015) for example, the Chrysler building which is composed of a stainless steel building has been only cleaned twice in 80 years. There will not be any degradation in its properties or performance as it is continuously recycled. Stainless steel is a 100% recyclable material. According to a case study conducted by International Stainless Steel Forum (ISSF), globally the recycled content of a stainless steel is 60% although in Europe it is 70%. Stainless steel has a notably lower percussion on the environment due to extensive recycling and recyclability compared to when it is produced solely from its principal material cradle.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
