With growing concerns about the harmful effects of fine particulate matter (PM), complaints related to fugitive dust from construction sites are also on the rise. Although conventional chemical compounds can reduce dust, they often face challenges in obtaining environmental certifications. In response, POSCO E&C has developed an eco-friendly dust suppressant that minimizes environmental impact while maintaining high effectiveness, earning Green Technology Certification from the Ministry of Environment. Additionally, through the in-house venture 'EcoPD,' we are working to commercialize this technology.

ISO 50001 is an energy management system standard established by the International Organization for Standardization (ISO). It is a management system standard that harmonizes technical and managerial aspects, enabling companies to systematically establish and continuously manage energy efficiency activities. POSCO E&C obtained this certification for the first time in 2023 to proactively respond to regulations such as the Construction Industry's Greenhouse Gas Target Management System and to address climate change company-wide.

POSCO E&C developed and has been operating POEMS (POSCO E&C Environmental Management System), a computerized environmental management system compliant with ISO international standards. While the system was maintained with minor updates, a comprehensive renewal was undertaken to enhance on-site convenience and work efficiency, in line with recent trends such as mobile apps. It was launched at the end of 2023 and now serves as a tool for realizing environmentally friendly construction sites.

POSCO E&C compensates for damage through simulation program when a noise damage occurs during a construction. We have developed the nation’s first 3D simulation of construction noise, which enables to estimate the noise damage within three days, which originally took two months. It evaluates the civil complaint risks upon order intake, decides how tall soundproof walls should be during construction, determines whether it should apply noise reducing methods, etc. As such, applying this technology facilitates the decision about installation of noise reducing facilities and prepares grounds for compensation for damage.

In the process of dismantling the aluminum form used in the frame construction, there occurs thunder-like noise over 150 dB. POSCO E&C has developed a method to reduce the shock noise and obtained the patent for the method. We are making continuous improvements by combining the existing polycarbonate insulation panel with vinyl bubble mesh or securing the safety of workers and enhancing workability through the installation of a passage. In addition, we have set the standards for application of an adequate insulation panel and shock-reducing method considering the distance between the noise source and the damaged areas and the work conditions. Relevant videos are also made and distributed for field workers to easily understand such process.

POSCO E&C has developed and is operating a dry wheel-cleaning facility using structural steel. Residual soil and water that can’t be removed solely by the wet wheel-washing, which is the legal standard, can be a major cause of civil complaints of the area adjacent to the construction field due to car and road pollution and ice formation in winter. Through dry wheel-cleaning facility, we are playing a role as an eco-friendly company that maintains clean environment for local residents and achieving zero law violation.

Field workers find it difficult to follow the water sprinkling measures due to the issues such as frequent change of working locations, electricity leading-in, water supply, distribution of manpower, etc. Therefore, POSCO E&C has developed an unmanned high-speed sprinkler after deriving the idea from a sprinkler for agricultural use, discussing, and making a sample. The apparatus has many strengths as it can be installed in areas where electricity can be reached, operated unmanned, save water, sprinkle water to wide area, and is movable. It can be applied to various fields, including demolishing sites, roads, construction, and plant. The unmanned sprinkler became the winner of the Chairman Prize at the 16th Excellent Construction Environment Management Cases Contest, which was organized by the Korea Environment Construction Association and sponsored by The National Assembly Environment & Labor Committee, the Ministry of Environment, the Ministry of Land, Infrastructure and Transport, and the Korea Environment Corporation.
