Air Pollution Prevention

The Company complies with regulatory guidelines and rules of the Stationary Pollution Sources Installation, Operating, and Fuel Use Permit, and has installed a bag filter dust collection facility in the steel structure sandblasting plant at Evergreen Steel Corporation’s Hsinying Factory, to prevent particulate matter produced in the process of sandblasting from directly diffusing into the atmosphere. In 2022, all values from regular monitoring of emission sources met standards for air pollutant emissions.

Water Pollution Prevention

The Company's main businesses are steel structure production, assembly, and cargo container repair and cleaning. The steel structure manufacturing process does not produce industrial wastewater, except domestic sewage from everyday office administration. The wastewater from the container cleaning process goes through 16 processes, such as sedimentation, rapid and slow mixing, chemical sedimentation, equalization, and thickening and dewatering, before being discharged to the wastewater treatment plant in the industrial park. Water quality met all effluent standards in 2022.

Waste Management

All kinds of waste are contained in storage sites according to the law, and different types of waste have signed contracts with qualified transporters and entrusted a legal final disposal factory or recycling factory to perform recycling and cleaning operations to ensure the legality and safety of final disposal. The wastes at the factory are mainly general waste of employees, inorganic sludge, mixed waste wood, mixed waste plastic, scrap iron, submerged arc welding slag and night soil. Recyclable material is collected for recycling. Other unrecyclable waste is disposed of by incineration or landfill. The Taipei head office is an administrative office unit, so there is no commercial waste or hazardous industrial waste.
Before signing the contract for the outsourced removal and disposal of factory waste, it is necessary to confirm whether the entrusted cleaning and transportation enterprise has a clearance and transportation registration license issued by the competent authority. After clearing and processing, reporting the production, storage, clearing and disposal of industrial waste through the Internet, and declare the information for three years.
The total waste output of EGST in 2022 was 8,445.89 tons, the annual output of final disposal waste was 444.53 tons, the total amount of waste resources was 8,001.36 tons, and the waste recovery rate reached 95% (scrap iron + submerged arc welding slag), more than meeting the EPA's 85% annual recovery target.
