The World's
Greenest Aluminum

Icelandic aluminum is a world leader when it comes to minimizing environmental impacts. The world’s lowest CO2 emissions are achieved with a combination of well-run, state of the art methods and facilities, and electricity generated exclusively from renewable resources. With continued focus on a variety small improvements – increased recycling, better raw materials etc. – we have managed to reduce our carbon footprint very close to the practical minimum achievable with current processes.

Iceland is one of only a few countries that produce practically all their electricity from renewable resources. Most aluminum smelters use electricity from natural gas, coal or oil, with the result that the world average carbon footprint is estimated to be around 12 tonnes CO2 / tonne Al – almost tenfold that of Icelandic smelters. With steady improvements to our methods and processes we have decreased our own CO2 emissions by about 75% from the year 1990.

With Iceland’s supply of green energy, state of the art technology and a first-rate workforce, our product becomes the world’s greenest aluminum. And that’s before the virtually endless recycling process of our metal even begins.

609,380 tonnes Al2O3

The production process of aluminum isn’t all that complicated. Aluminum is a very common element but it's almost never found in nature unless bound with other substances, such as oxygen. We use aluminum oxide — oxygenated aluminum, or AL203— a fine-grained powder which is imported to Grundartangi by sea and transported into the plant in a closed-curcuit system of pipes and silos.

4.639.000 MWh

Compounds of aluminum and oxygen in aluminum oxide are very strong. In order to separate the elements, we need not only a lot of energy, but also a new partner for the oxygen. The oxygen (O) is separated from the aluminum (Al) by electrolysis and bound to carbon (C). This creates CO2 and what remains is pure aluminum.

317.386 tonnes Al

The product is pure aluminum that is moulded into units that are easy to handle, stacked up in container and driven to a cargo ship waiting in the dock, just 600 metres from the aluminum plant itself. Norðurál uses some of its aluminum to develop alloys that can be four times as strong as aluminum and much more valuable. In the end, all products made by the plant get delivered to international markets where they are used for packaging, transport, electronic devices, construction and more.

Responsibility – Safety
– Efficiency

Norðurál produces high quality aluminum in a responsible, safe and efficient manner. Our quality control protocols are subject to regular review in a process of continuous improvement. All staff is encouraged to participate in maintaining and improving the quality of our operations at all levels.

The safety and health of our people is our first priority, every single day. Norðurál is the largest workplace in the West of Iceland and plays a pivotal social role – not only as the principal source of income for hundreds of families, but also more generally for the economical, environmental and social well-being of the region as a whole. We take our responsibilities seriously, as well as our commitment to operate well within the framework set by law and regulations.


Green Accounting

Green Accounting

Green accounting is a thorough register of all materials brought to the aluminum plant and delivered from it. Our aim is to maximize the efficient use of materials and provide a precise account of how undesirable materials are disposed of.

Green accounting has various direct and indirect positive effects on company culture. It increases care in the use and disposal of all materials and improves safety in the operation of heavy equipment. At the same time, green accounting provides a valuable tool for identifying inefficiencies and unsafe practices, minimizing waste and improving health and safety.

The year 2018 passed without a single major environmental incident. Filtration systems ran smoothly and all monitoring measurements were well within operational license limits.

Decreased Emissions Allowances
with Increased Production

Norðurál’s aluminum plant in Grundartangi has an operations license for producing up to 350 thousand tonnes of aluminum per year. A new license was issued by The Environment Agency of Iceland in 2015, with expiration on 16 December 2031. According to the new license the company’s emissions allowances for fluoride and SO2 have been slightly reduced.

In the new operating license of Norðurál the allowable emissions for fluoride have been reduced from 0.5 kg to 0.47 kg/t on average per year if the yearly production is under 320 thousand tonnes. If yearly production exceeds 320 thousand tonnes, allowable emissions are reduced even further, to 0.43 kg/t.

Auditor's Statement

I have reviewed and audited the information presented in Norðurál’s green accounting for the year 2018. The books have been reviewed with regard to whether the information stipulated in articles 6, 7 and 8 of Regulation No. 851/2002 is available for scrutiny and whether the numerical information presented complies with data from the financial records and the company’s monitoring of key figures in environmental matters.

After having conducted a review of the data, my opinion is that the green accounting meets the conditions of Regulation No. 851/2002 and gives a thorough account of the company’s environmental impact in the year of 2018.

Efficency and Economical
Use of Resources

Norðurál is one of 103 Icelandic companies who have committed to the reduction of greenhouse gas emissions and waste, as well as to providing detailed monitoring and reporting of environmental impacts. All our planning and engineering projects aim to continue the reduction of greenhouse gas emissions and minimize environmental impacts. Norðurál is at the forefront in developing and implementing most major measures that reduce emissions and environmental impacts, including minimizing anode waste and electric spikes, and generally eliminating unnecessary waste

Norðurál uses tens of electric vehicles to transport workers and goods locally. For the growing number of staff members who use electric and hybrid vehicles to get to and from work, several charging stations have been installed, offering free electricity to staff and visitors. In 2018, ten new charging stations were added, and four pre-existing ones were converted to fast-charging stations.

Increased Recycling

Norðurál's ongoing programs aim to involve employees in environmentally beneficial projects and to raise awareness on environmental matters. Staff bonuses are partly based on company performance in minimizing negative environmental impacts.

75% of all waste from operations is recycled, and we're close to the theoretical limit set by the present state of technology and methods in aluminum production. One area where we can still improve is in general "household" waste throughout the Company. We have significantly increased sorting of general refuse to increase recycling of leftover food, packaging, office supplies and the like. Access to fast-charging stations for electric cars is free for all staff members and visitors, and various diesel-powered vehicles have been replaced with electric vehicles.
