Metal is a product of a lengthy process that includes ore extraction, ore processing to remove oxides, casting, forging, and other steps. While exploiting already dwindling natural resources, this process creates huge amounts of emissions and other types of pollution.
With gradual decline in the environment, the emerging technologies have laid a pathway to potentially reduce the metal industry’s harmful impact on the planet. This may also be viewed in terms of building a circular economy rather than a linear one. Circular economies are restorative and regenerative by design and aim to keep products, components, and materials at their highest potential and value at all times. The only way to do so is to implement recycling at every level, not just in metal businesses, but also in areas where metal is utilized extensively.
Steel manufacturing, for example, has a number of side effects, including CO, SOx, NOx, PM2, water pollutants, hazardous wastes, etc. (https://www.worldsteel.org/en/dam/jcr:c3acc5fd-e3c2-458c-a2cc-8c4880b9334c/Steel%2527s+contribution+to+a+low+carbon+future.pdf). The major environmental impacts result mainly from coking process and iron manufacturing process.(https://www.worldsteel.org/en/dam/jcr:16ad9bcd-dbf5-449f-b42c-b220952767bf/fact_raw+materials_2018.pdf). In 2013 in Australia, the steelmakers began using the world’s first “green” steelmaking process. The process calls for substituting coke and coal with plastic bags and bottles that would otherwise end up in city dumps or landfills. Nearly 30% of the coke and coal has been replaced with conventional carbon-containing materials and importantly, greenhouse gas emissions, energy consumption, and production prices all have shown a significant decline.
Carbon is a critical raw ingredient in steel production using the electric arc method. Almost 40% of the world's yearly steel production is now produced using this approach. Moreover, Veena Sahajwalla discovered that recycled truck tyres are a more environmentally friendly alternative to coal (https://en.m.wikipedia.org/wiki/Veena_Sahajwalla). It could prevent over 2 million tires from ending up in landfills while simultaneously creating a renewable energy source.
“Trash for cash” is the new order of the day in a growing industry known as secondary metals. Metal recycling companies in UAE that are equipped with technology that is both sustainable and energy efficient have a big role to play. In the metal industry, such companies have a pivotal role in developing the “Green” attitude in the metal industry. Scrap metal yards in Dubai, for instance, helps in spearheading metal recycling and contributes to both ferrous and non-ferrous scrap metals that can be processed back to a form of raw material that can be used to form new metal alloys.

The global market for metal scrap has significantly grown over time. With advancements made in the recycling technologies and awareness that drives the sustainable approach, it is indisputable that this trend will continue to move upwards with iron, steel, and stainless-steel scrap.
