Russian mammoth Aluminium producer, Rusal is well advancing towards the production of a carbon-free version of the metal, and the company aims to release it by 2021. The innovative move by Rusal is in line with consumersâ demand, as significant consumers of base metals such as automotive industry, construction, consumer goods, etc., are shifting their working culture towards a carbon-restrained environment.
Rusal aims to develop a better carbon-free products line, and the company is progressing through scientific innovation to change the way aluminium is produced along with many other such innovations. The traditional method of generating aluminium is through alumina by smelting. The process places a coal anode in a bath of alumina and other materials. High-Intensity electricity is then passed through the bath to produce aluminium from alumina.
The traditional process generates a lot of carbon footprints, and the raised concerns on environmental pollution by various economies, who are the potential consumer of Rusal aluminium led the company to design a sustainable development objective. The objective mainly focuses on reducing the carbon footprints while producing aluminium from alumina and it continues to test its own design and technology with inert anodes.
As per the company, the use of inert anodes will mark the absence of greenhouse gases and polyaromatic hydrocarbons released during aluminium production from conventional methods. Rusal also mentioned that the company is developing a line of green aluminium alloys with inert anodes.
Another innovative measure taken by the company was the introduction of RA-550 superpower generation cells, which reduced the intensity of electrical energy required for the aluminium production. The company adopted the RA-550 superpower cell in 2017 at Sayanogorsk Aluminium Smelter and received superior results beyond the expectation of the company. As per the company, the new innovative RA-550 superpower cells consume 10-15% less power than previous generation cells.
Apart from the measure adopted to reduce the carbon emission from the production process, the company is also developing low carbon footprints product lines.
One such product line of the company is Rusalâs ALLOW aluminium, which as per the company empowers its customers to reduce the carbon footprints of their products. The company mentioned in its press release that ALLOW is made from renewable hydropower, which is a significant source for the company for aluminium production.
As per a publication (Cullen and Allwood 2013), the production of aluminium globally consumes around 3.5% of global electricity production, and it also accounts for 1% of global carbon dioxide emission.
Rusal, with its innovative technology and low carbon line of products, is adapting to the changing trend in the global economy. The trend, which is marking a shift of economies towards zero-emission economies have seen stringent actions in coal industry as well.
Rusal with its innovation, now is an open competitor for other companies such as Rio Tinto, Alcoa, etc., who are working on the same objective as adopted by the company, i.e., to reduce the carbon footprints in the product line and create additional enhanced ways for green production and mining of metals.
