In the first six months of this year, Slatina-based Alro has completed over USD 16 million investments in both the primary aluminium and the processed aluminium segment, a press release informs. The investment program will allow Alro to expand its customer base in industries using high-quality aluminium. Alro’s business plan for the period 2017-2021 predicts total investments of over USD 190 million.
Moreover, the largest aluminium producer in continental Europe (excluding Russia and the Scandinavian Peninsula), implements a long-term program of over USD 100 million to increase energy efficiency and to reduce the company’s specific consumption, as part of the “Green Factory” program.
The “Green Factory” concept aims at using state-of-the-art green technologies that will enable the company to produce high added value aluminium products. In addition, they will contribute to meeting Alro’s close to zero-waste and zero emissions targets
In the primary aluminium sector, the company replaced DC rectifiers, resulting in a savings of 30,000 MWh/year or USD 1.5 million annually. It also implemented computer-assisted central supply technology, as well as gas capture and purification in gas treatment centres, which led to a reduction in direct consumption of electricity of about 1,000 kWh/t of aluminium, saving 200,000 MWh/year, or about USD 10 million annually.
The consumption of natural gas in the production of anodes has also been reduced three times by modernizing the baking furnaces, and in melting and metal making furnaces it has decreased by 20 percent. Water consumption has also decreased about fivefold thanks to the construction of recirculation and water treatment stations.
In addition, the construction of the eco-foundry for the processing of aluminium waste by melting led to a saving of over 95 percent of electricity consumption compared to the production of electrolytic aluminium.
In the processed aluminium sector, Alro has upgraded processing lines, introduced new technologies and equipment with high energy efficiency. In addition, it has implemented the concept of predictive maintenance and digitization, the release reads.
All these has resulted in an increase by four times of processed aluminium production, a reduction in specific electricity consumption of five times and a reduction in natural gas consumption of 10 times. The state-of-the-art technology has enabled the company to introduce new types of products in its portfolio, for automotive and aerospace industries.
