The International Stainless Steel Forum announced the winners of their two Premier Annual Awards during their Annual Conference in Helsinki on 25 and 26 May. The winner of the Sustainability Award is Outokumpu, for maximising water recycling in their Cold Rolling Plant in Mexico. The winner of the Safety Award is North American Stainless, for their Safety Performance Improvement project.
San Luis Potosi, Mexico, where Outokumpu’s Mexinox cold rolling mill is located, is an arid area, where groundwater is a scarce and valuable asset for people and livestock. Reducing the volume of water which is required for their production increases the volume that can be used for other vital human needs.
The progression of water recycling at Mexinox has been based on long term projects. In 2001 the environmental regulations made it necessary to examine new ways to re-use and re-cycle water in their production processes.
This improvement process has continued during the intervening years. Among the most recent investments is a new Crystallizer plant, which was installed in 2013. This plant has resulted in savings in energy and money as well as providing additional environmental protection. CO2 emissions from this water treatment process decreased by 95%. Their investments in wastewater treatment plant processes have made water recycling significantly more efficient. The solution with high concentration of salts coming from the evaporation phase is heated in order to evaporate the water and to collect the waste material in crystal form. Today 99% of waste waters are treated, recycled and reused in cold rolling plant. This level is considered to be unique in the industry. To follow up on the progress, the plant has established yearly internal targets for water use in the mill. The savings in fresh water consumption are equivalent to the quantity consumed by 1,100 households. For 2015, fresh water consumption in the cold rolling mill was extremely low (1.22 m3/t) and well below the target (1.50 m3/t).
The plant has also achieved its target of saving water use on a per rolled ton of steel basis. “For us to continue recycling water is important because it allows us to contribute to environmental care as an organization. We fulfil the environmental regulations and give an example of social responsibility”, says Jorge Vieyra, head of production and environmental management at Mexinox.

In 2014 North American Stainless ended the year with 4.51 recordable injuries per million man hours worked and 1.13 lost time injuries. They recognized that greater employee engagement in safety programs could lead to further reductions in injury levels. Some employees were hesitant to participate in safety programs and others seemed to feel that safety was not their responsibility. Management realized that they needed a greater level of involvement, input and participation from their employees to improve the safety process.
In order to achieve this goal, they did three things:
For 2015 their employees completed 19,628 BBO’s and 113 near miss reports. All near miss reports were investigated as if they had been an injury and alerts were distributed to all employees for review and discussion and any BBO’s that required follow-up were automatically entered into the Safety Review system.
Management noticed that employees have become much more aware when it comes to safety. If anyone enters the plant without the appropriate PPE, they will be stopped. Employees have become much more open with the Safety Coordinators and they raise issues and ideas about safety.
With the increased level of employee awareness and participation NAS have been able to significantly reduce their recordable and lost time injuries and they ended 2015 with a 0.93 Total Recordable Injury Rate and a 0.07 Lost Time Injury Rate, which is an outstanding improvement in safety performance after only one year.

The International Stainless Steel Forum announced that the winners of this year’s Sustainability Award is Aperam for reducing emissions to air, a project which lasted from 2005 to 2015. The Safety Award was given to Jindal Stainless for reducing carbon monoxide levels to eliminate the explosions in the dust plant.
The Aperam Belgium plant is located near the city of Genk, which has 65,000 inhabitants. They faced the challenge of significantly minimising dust emissions so they did not affect air quality in the local area. They have implemented an extensive action plan at three levels: operational; managerial; and communications. They also organised an Environmental Day for an open exchange with all stake holders. This allowed them to share their test results and data measurements in a transparent way. They managed to significantly reduce their emissions to air. Compared to 2006, they reduced emissions to air by 72% in 2014. Due to lower dust emissions, they have received fewer complaints from the neighbourhood in the last four years. This shows their good results and a positive and strong relationship with local residents. Finally, their efforts have resulted in Aperam obtaining a new environmental permit for their plant.

Jindal Stainless reduced the carbon monoxide levels to eliminate explosions in the dust plant. The carbon monoxide level must be controlled to prevent the risk of explosions. The opening and closing of valves was controlled so that when the CO content in the fume gas exceeds 3%, the valve opens to the maximum to provide fresh air to the bag house. During this operation the valve temporarily halts the suction of dust. After this modification, the chance of an explosion in the bag house was eliminated.

The International Stainless Steel Forum (ISSF) presented its annual Sustainability Awards during the organisation’s 18th conference (ISSF-18) held in Rome. TheISSF has split the Sustainability Award into two categories from this year, to recognise sustainability initiatives in two categories – People and Profit/Planet.
Fifteen member companies submitted a total of 27 case studies for consideration. The overall standard of the submissions has been improving year-by-year and this year the judging process was made extremely difficult by the strength of the competing entries.
In the People category, Outokumpu was recognised for its landmark study of the incidence of cancer in Stainless Steel industry employees in comparison with the figures shown by the general public. Carried out in cooperation with the Finnish Cancer Registry (part of the Finnish National Institute for Health and Welfare), the study examined cancer rates amongst people employed at the Kemi Chromite Mine and the Tornio Ferrochrome and Stainless Steel Mills during the 34 years from 1967 to 2004.
The study found that the overall incidence of cancer among employees was similar to that which was found in the general population in the same region, while the risk of lung cancer risk was actually lower among Stainless Steel Industry employees. Read the full case study here
The winner of the Planet/Profit category was Nippon Steel & Sumikin Stainless Steel Corporation (NSSC). Over the past 15 years the company has followed a detailed action and investment plan to recover and recycle refractory waste from its operations.
When the project began, NSSC only recycled 6% of its refractory waste. As a result of the improvements and investments which the company has made, that recycling rate is now 100% which has dramatically reduced landfill space required and provided NSSC with a valuable source of steelmaking raw materials.

The International Stainless Steel Forum (ISSF) has announced that the 2013 Sustainability Award was presented to Acerinox during ISSF’s 17th Annual Conference which is being held in New Orleans, USA. Acerinox’s winning entry outlined how the company is recovering valuable raw materials from scale created during the stainless steel production process.
Twelve companies submitted a total of 25 case studies for consideration in the 2013 Award. All entries were ranked against five criteria:
Acerinox’s entry scored the highest against these criteria. In their case study, Acerinox outlined how they have developed a new process to package waste scale into briquettes which have a high metallic content. The briquettes can be fed back into the furnace to make new stainless steel. This process has a positive environmental impact as less waste needs to be transported and less raw materials need to be brought in.
All 25 case studies are available in the 2013 Sustainability Award booklet which can be downloaded here.
Beijing, 17 May 2012. The International Stainless Steel Forum (ISSF) has announced the winners of its 2012 Sustainability Award. The Award was first presented in 2011 and recognises the outstanding contribution of ISSF Member companies to the sustainability of the global stainless steel industry.

The International Stainless Steel Forum (ISSF) has granted the first ISSF Sustainability Award for Outokumpu. The acknowledgement was received in ISSF Annual General Meeting in Madrid, Spain on 22 May 2011. The recognition was based on Outokumpu's determined actions and great achievements in reducing waste to landfill and increasing material efficiency in Sheffield.
David Martin, chairman of the ISSF Health & Environment Committee comments: "Outokumpu's Sheffield melting shop case is an excellent example of sustainable development. Minimising waste is in everyone's interest and this case demonstrates significant improvements with clear figures."
Outokumpu established a sustainable recovery and re-use route for different stainless steel waste in Sheffield. Slag was re-used in the production of asphalt and waste refractory material was used as a substitute for limestone in the stainless steelmaking process. These actions have led to dramatic reduction in waste to landfill. Since 2007 over 80% of all slag has been recovered and re-used as road stone in the asphalt production. During 2010 half of all refractory waste generated on site was re-used as a lime substitute.
Outokumpu's CEO Mika Seitovirta comments: "I'm pleased and honored to receive recognition for our efforts in the area of sustainability. This encourages us to work towards our long-term target - minimum waste in the production process."
