Actively participate in climate change
response measures.

Beyond severe climate change happening globally, we are entering an era of the climate crisis. Being environmentally friendly has become an essential element of corporate management, and major countries around the world are strengthening their carbon reduction goals and expanding carbon regulations. Accordingly, KCI is carrying out eco-friendly management and carbon reduction activities by deriving a roadmap to achieve carbon neutrality and reduce greenhouse gas and energy consumption.

Climate Change Response

KCI aims to develop into an eco-friendly leading company in the chemical industry by actively participating in initiatives to respond to the climate change crisis with the goal of eco-friendly management. We are striving to become a responsible member of the global society by reducing greenhouse gas emissions and energy consumption and achieving carbon neutrality by 2050.

2050 Carbon Neutrality Roadmap
  • Reduce 20%

  • Reduce 50%

  • Reduce 100%

  • Transition to renewable energy

  • Active carbon emission reduction efforts

  • Energy efficiency improvement

  • Development of eco-friendly products

Usage &

Striving continuously to solve environmental problems caused by resource usage.

Continuous efforts are needed to promote reuse, recycling, and the circulation of resources to prevent the depletion of natural resources and address environmental issues caused by resource usage. In particular, KCI is continuously reducing environmental impacts by practicing waste separation and minimizing waste generation to meet the strict requirements for managing hazardous chemicals and waste.

Resource Use

Water scarcity is intensifying worldwide and the changes in rainfall patterns and rising sea levels caused by climate change are accelerating. KCI recognizes the importance of water resource management and is actively implementing activities to reduce the amount of water used and wastewater generated.

  • Water Pollution and Wastewater Management

    To minimize the discharge of hazardous substances, we have set discharge limits to below 80% of legal discharge standards and regularly monitor discharge levels. We are reducing water consumption and safely releasing wastewater after secondary treatment.
  • Air Pollutant Management

    We have established guidelines for air, water, noise, and vibration management to actively respond to air pollution and environmental issues, conduct environmental impact assessments, as well as record and practice hazard management plans.

Waste Management

KCI has established waste management guidelines to minimize waste generation and to also increase the efficiency of resource use. In accordance with the guidelines, we designate the authority and role of the waste-related person in charge (Plant manager, Environment safety department head, etc.), identify the status of waste generation, report treatment plans, separate and collect waste, etc. according to the legal obligations. We maintain records of hazardous information according to the Waste Management Act for the waste subject to the environmental minister's notification, and design eco-friendly processes to minimize environmental impact and prevent the generation of unnecessary process byproducts.

Handling and management of hazardous chemicals

KCI has established guidelines for the management of hazardous chemicals to prevent accidents that may occur during the handling of hazardous chemicals. These guidelines define the authority and role of the person in charge (plant manager) related to the handling of hazardous chemicals and regulate the methods of storing, handling, and using hazardous materials, as well as procedures for responding to leakages. We conduct regular and random safety checks and safety diagnoses to prevent accidents and ensure safety management, and in particular, facilities for handling hazardous chemicals are operated after a pre-operation check.
