Key initiatives designed to increase the waste recycling rate to 67.10% by 2030 include expanding the sorting process at internal waste collection sites, providing more combustible waste to recycling companies (from 45% in 2023 to approx. 70% in 2030), and adjusting the amount of wood delivered to local residents (50% by 2030 from the current level). We also plan to implement a series of activities to improve our recycling in the long term such as selecting and improving recyclable items among wastes disposed in landfills, reviewing the possibility of partial recycling of designated wastes, and designating recycling companies in advance to release new wastes.

Special Case
  • #1Recycling wood

    As an example of waste recycling, Hanwha Ocean selects various types of wastes by property such as synthetic resin, synthetic rubber, wood, and household waste and sends them to recycling companies to produce solid refuse fuel (SRF) and wood chips, plywood, and square timber. The SRF produced by recycling companies using our waste as a raw material serves as a renewable energy source. They are supplied as an auxiliary fuel for power plants, district heating, and industrial use, contributing as a green energy source to replace bituminous coal. Additionally, we promote the circulation of resources and take the lead in environmental protection by producing wood chips, plywood, and square timber from waste wood, and converting them into high-value products.

  • #2Recycling slag and dust

    Hanwha Ocean sorts slag and dust by property, which are then sent to competitive recycling companies. Recycling companies use these materials to produce cement additives, fillers, and other products as well as moldings that are used as raw materials for metal and steel products. Such recycling process is considered an important example of promoting efficient use of resources and contributing to environmental protection. Our approach contributes to sustainable environmental management and resource circulation by turning industrial waste to valuable resources.

  • #3Recycling paint waste and used oil

    Hanwha Ocean separates waste paint cans and oil drums and sends them to recycling companies for environmental protection and resource recycling. Waste paint cans are converted into raw materials for steel products, and they serve as important resources in the steel industry. On the other hand, waste oil drums are used to produce recycling tubes, adding value as crucial resources. Such recycling activities go beyond the simple activity of reducing waste; they contribute to sustainable environmental management and promote the efficient use of resources.

Water Pollution
Management

In an effort to promote sustainable environment, Hanwha Ocean has established internal management standards that are about 30% stricter than the existing legal discharge level under the Water Environment Conservation Act and the Sewerage Act, taking the lead in the management of water pollutants. Our efforts do not only meet legal requirements but also are designed to implement our corporate responsibility and commitment to environmental protection. Our proactive approach contributes to controlling water pollution effectively and maintaining a clean and healthy water environment.

Chemical Substance
Management

Hanwha Ocean strives to minimize the negative impact of chemical substances used to construct ships on the health of our employees and the environment. Accordingly, we thoroughly manage the entire process from procurement to disposal to ensure the safety of chemical use. In addition, we apply and promote multiple options to reinforce the management of chemical substances, including establishing an automatic check system, developing AI-based research and alarm functions, investigating shipowner and vendor customs clearance items, and manually managing chemical substances.
