Doosan Corporation Electro-Materials minimizes the environmental impact and improves the operating efficiency through the green management.
Reducing Energy Use through Equipment Replacement
We analyze the manufacturing process of respective Business Groups/Business Units to identify areas whose energy consumption is heavily intensive, and undertake energy efficiency initiatives to address these areas. At Doosan Corporation Electro-Materials, each of its plants set energy use reduction targets and took action accordingly, and improved pump equipment and relevant processes to generate KRW 86 million in annual energy savings.
Climate Change Response Strategy and System
We fully support the Korean government’s policy to curb GHG emissions as a way to do our utmost in responding to climate change and minimize our environmental footprint to fulfill our social responsibility. To this end, we established a system to respond to climate change and to reduce energy consumption based on our three strategic pillars of green management, and this system guides our green management endeavors. Specifically, our GHG emissions/energy statements for the period between 2011 and 2014 were verified by the authorized national verification body and were reported to the Korean Ministry of Environment in 2015, which increased the reliability of our environmental data.
Building on such experience, we aim to create a dedicated organization to handle GHG emissions trading schemes, build relevant operational processes, and set reduction measures so as to gradually strengthen our capacity to respond to such schemes. We disclose our climate change response activities and CO2 emissions through our CSR reports, public disclosures, and the environmental information disclosure system. Since 2009, we have been participating in the Carbon Disclosure Project (CDP) to ensure that our endeavors to respond to climate change are evaluated by external organizations.
We are building a company-wide chemicals management system to prevent chemical incidents that occur frequently in recent days and to comply with strengthened regulations that govern the use and management of chemical substances. Furthermore, we developed our chemicals inventory to verify those chemicals that we keep and to comply with relevant regulations. Each of our Business Groups educates their research units and shop-floor managers on the Chemicals Registration and Evaluation Act and the Chemicals Management Act, and set forth their chemicals management guidelines to systematically respond to relevant governmental regulations. In 2015, we identified such key managerial areas as capacity-building, legal assistance, and internal activity diagnosis/improvement, and took improvement measures accordingly. Particularly, we update the legal requirements imposed on our chemicals management inventory on a quarterly basis through external expert organizations, and periodically share newsletters to manage chemicals-related risks.
Prevention of Chemical Incidents
In purchasing chemical substances, we perform EHS impact assessments on the basis of MSDS*, and confirmation statements. This ensures that the chemicals that we use comply with relevant laws and regulations and employees in charge of chemicals management attend mock drills and receive regular training on chemical handling standards. We also placed disaster control boxes to prevent chemical leaks in the workplace and installed leak prevention devices to fundamentally protect our local communities from suffering any damage and to establish a swift emergency response system. In 2015, all our worksites were subject to chemical substance analysis to prevent chemical leaks and identify potential risks.

Managing the Quality of Effluents through In-House Standards
We ensure that the effluents from our worksites have only a minimal impact on their nearby ecosystems. Our in-house threshold is 50% of the legally-permissible discharge levels, and this contributed to reducing the concentration of water pollutants in final effluents. Doosan Corporation Electro-Materials analyze discharge approval items bi-weekly and semi-annually or more often respectively to monitor their compliance with in-house standards. They also analyze the entire items of both raw wastewater and effluents twice a year to identify the pollutants that they discharge. Furthermore, all our final effluents go to sewage treatment plants before their discharge into the water system to prevent water pollution.
Process Waste Management
The waste generated from each of our processes is categorized and managed in accordance with their respective disposal methods from recycling to landfilling and incineration. We fully abide by waste-related regulations, and perform regular follow-up assessment and education on waste treatment service providers so as to dispose of such waste in a transparent and lawful manner. Our comprehensive waste management information system (Allbaro System) enables us to classify and manage waste according to its properties and phase. In 2015, the waste we generated was treated through recycling (77%), landfilling (1%) or incineration (22%).
Controlled Waste Management
We follow legally-allowable procedures in managing controlled waste so that any leak of such waste leads to only minimal damage to our local communities. In 2015, our generation of controlled waste fell by 4.5% from the previous year to 7,892 tons, all of which was safely treated. Doosan Corporation Electro-Materials creates waste cards whenever designated waste is generated and registers these cards on its EHS IT system to track and manage such waste until it is properly disposed of. Its Doosan technical center developed and is currently using waste identification stickers to categorize and manage waste according to their physical phase.
Water Resource Management
Our water resource management aims to ensure a stable supply of water and reduce our risk exposure caused by water resource depletion. Doosan Corporation Electro-Materials classifies its water resources into tap water and groundwater at three of its plants (Jeungpyeong, Gimcheon, Iksan). Furthermore, it discontinued the use of two of the five groundwater mining facilities, and is minimizing the amount of groundwater collected at the remaining three facilities to prevent groundwater depletion. Wastewater reuse devices are also operated to reuse 50% of the wastewater as process water, and the quality of recycled water is managed through R/O membrane* filter maintenance.

Air Pollutant Management
We ensure that the air pollutants emitted from our worksites are 50% or less than the legally-permissible threshold. Complying with these stringent in-house regulations enables us to reduce the emission of SOx and NOx. Specifically concerning emission/control facilities that change their substances consumed or have a significant environmental impact, each of their air pollutant items is measured and monitored while newly-generated pollutants are managed through continued self-initiated measurement as well as a preliminary analysis.
Environmental Impact Assessment System
To reduce environmental impacts and risk-related costs, Doosan Corporation Electro-Materials conducts a preliminary EHS impact assessment before commencing an investment or construction works from which environmental risks may arise, thereby creating a safe work environment. Doosan Corporation Electro-Materials sets development objectives that take into consideration target quality, target cost, and environmental impacts at the stage of developmental project planning. At the stage of basic design, we examine whether the design reflects considerations about environmental impacts to enhance reliability in the basic design. At the stage of development completion, Doosan Corporation Electro-Materials conducts an objective review and evaluation to determine whether the design takes environmental impacts into consideration and receives feedback on the progress of the development project. Doosan Corporation Electro-Materials will work harder to minimize the environmental impact of its businesses by increasing environmental spending.
Climate Change Response Strategy and System
Doosan Corporation Electro-Materials is actively engaged in government-led greenhouse gas mitigation initiatives and committed to responding to climate change and fulfilling its social responsibility to minimize environmental impacts. Under the 3 green management strategic pillars, Doosan Corporation Electro-Materials established climate change response and energy use reduction systems and organized related activities. First, we created a TF dedicated to the target management schemes, and the task force has conducted energy use and GHG emissions surveys and kept track of policy trends for the past 3 years. Doosan Corporation Electro-Materials thus created a system for measuring and reporting workplace greenhouse gas emissions as a foundation for more effective response to climate change. Building on this experience, Doosan Corporation Electro-Materials is enhancing its capabilities to respond to the GHG Emissions Trading Scheme by creating a team dedicated to the GHG Emissions Trading Scheme, dedicated business process and mitigation plan.
Waste Management System and Performance
Doosan Corporation Electro-Materials manages waste produced in each process by classifying it by disposal method, such as recycling, reclamation or incineration. To ensure transparent and legal waste management pursuant to waste laws, Doosan Corporation Electro-Materials regularly conducts follow-up evaluations and training for waste disposal companies.
