Save Resources & Preventing Pollution
Doosan Corporation Mottrol minimizes the environmental impact and improves the operating efficiency through the green management.
Improving Pump Control Logic for Fuel Efficiency Gains
To help adopt eco-conscious designs for construction equipment, Doosan Corporation Mottrol is developing excavator pump control logic to improve fuel efficiency and reduce CO2 emissions. This system employs a special control logic for fuel efficiency gains and a pump that uses electric signals to enable the high-speed control of hydraulic oil supply. This results in 12% or higher fuel efficiency against existing control systems while maintaining control performance. Doosan Corporation Mottrol will continue to develop and commercialize systems that further increase the overall energy efficiency of equipment, in addition to simply improving the efficiency of actuators*.

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.
Doosan Corporation Mottrol strives to minimize the environmental impact of its products caused by the use of harmful chemicals. It replaced those processes that generate substances regulated by RoHS* with more ecofriendly ones in order to prevent these environmental pollutants and to deliver safe products. Doosan Corporation Mottrol will comply with global environmental regulations and continuously undertake preventive measures.
*RoHS (Restriction of Hazardous Substances Directive) : EU guidelines that regulate specific hazardous substances and ban the use of such harmful materials as lead, mercury, and cadmium in electric and electronic products
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.
* MSDS (Material Safety Data Sheet) : Data sheets that describe information required for the safe use and management of chemicals
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%).
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.
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.
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.
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.
