Environmental Compliance Principles

Hyosung Heavy Industries adheres to the following principles to minimize pollution and environmental impacts and effectively manage environmental risks by adhering to environmental laws and regulations.

  • In accordance with environmental
    management policies, manuals,
    and procedures, we shall immediately
    reflect any amendments to environmental
    laws and regulations, carefully review
    environmental laws to manage
    environmental risks efficiently,
    and assess compliance annually.
  • We shall make efforts to reduce our environmental impact by establishing internal standards that are more stringent than legal requirements.
  • We shall transparently disclose our compliance with environmental laws and regulations to stakeholders through various channels, such as sustainability reports, the Env-Info System, and the CDP.

Environmental Management System

Every year, Hyosung Heavy Industries sets KPIs and objectives for environmental management items (e.g. environmental qualification management, environmental impact assessment, environmental compliance assessment, regulation management, air and water pollutant concentrations, waste generation, responding to stakeholder complaints), develops annual plans, and evaluates whether or not these objectives are met.

  • Water Quality

    Hyosung Heavy Industries' Changwon Plant conducts monthly water quality inspections to continually monitor the concentration of pollutants in water. In addition, we replace filtration systems, such as activated carbon filters and filter sand, in filter tanks at wastewater treatment plants on a regular basis to ensure that the concentration of discharged wastewater is within 50% of the legal standard.

  • Air Quality

    Hyosung Heavy Industries' Changwon Plant establishes stringent internal emission standards that are 50% of the legal air pollutant emission standard. Once we exceed our emission standards, we replace the activated carbon and bag filters as a precaution. In addition, we set a reasonable replacement cycle for activated carbon and bag filters relative to the production volume, and we continually monitor the production volume so that such filters are replaced according to their replacement cycle. Our Extra-high Voltage Transformer Manufacturing Team introduced an injector-type pulse to the descaling facility to provide solutions to existing problems such as the short lifespan of bag filters and high compressed air consumption. In addition, the Casting Team previously utilized an activated carbon adsorption tower to remove a substantial amount of pollutants from dip coating facilities; however, considering the challenges in maintenance and management due to the short breakthrough time of activated carbons, we reduced replacement time by installing an adsorption and catalytic oxidation equipment (Veraria) with regenerative media filters—the first in Korea.

  • Ozone-Depleting Substances

    Hyosung Heavy Industries rules out the use of substances containing chlorofluorocarbons, which are governed by the Montreal Protocol, an international treaty designed to protect the ozone layer.

  • Soil

    Hyosung Heavy Industries has no facilities that cause soil pollution.

  • Chemical Substances

    Hyosung Heavy Industries increased the management efficiency of chemical substances used in production by incorporating an Electronic Chemical Management System(ECMS) into our existing ERP-based computer system. Through ECMS, we analyze every procured material, and upon detecting materials containing chemical substances, we suspend the procurement until the managers at each business site verify and approve compliance with the regulations and licenses of their own database using the data of the chemical substances supplied by the supplier. We also conduct systematic operation of MSDS training simultaneously with the receipt of all materials. The Changwon Plant annually replaces existing hazardous chemicals with non-hazardous ones to create an eco-friendly workplace. It works to prevent the introduction of new hazardous materials by conducting preliminary environmental safety reviews.

  • Zero-Emission Vehicles (ZEVs)

    Hyosung Heavy Industries operates ZEVs, including electric vehicles, that can reduce air pollution and GHG emissions. We plan to increase the proportion of ZEVs to total vehicles over time.
