SK bioscience manages the amount of waste generated during the process to prevent environmental pollution caused by waste generation at a company-wide level. We monitor the entire process from generation to treatment and sterilize waste that may become contaminated between processes before shipment. In the case of designated waste disposal, which is hazardous waste that may degrade the surrounding environment, we continue our efforts by selecting an outside company to strictly separate disposal.

SK bioscience has no harmful untreated waste. All produced waste is processed by an external waste management company.
Hazardous Chemicals Management System
By creating an inventory, SK bioscience systematically manages hazardous chemicals at L HOUSE. Furthermore, we review the hazards of new chemicals before introducing them so that we can reduce the risk of hazardous chemical exposure or disposal to a wide range of stakeholder groups, including employees, nearby ecosystems, and local communities. We minimize the use of hazardous chemicals by closely managing it.
To further analyze and improve the management plan, we introduced the SHE IT system to computerize and manage the Material Safety Data Sheet(MSDS) and will use Chemical Hazard Risk Management(CHARM) for all chemicals that will be used at sites.
In addition, by introducing the Chemical Management System(CMS), we plan to invest in systematized management throughout the entire process, including the import, use, and disposal of chemical substances.
Hazardous Chemicals Safety Training
We provide training on primary chemical substances during new hire training and regular training for all employees to raise awareness of the dangers of chemical substances. We also provide training on MSDS when introducing new chemical substances.
Moreover, we train handlers by preparing standards for wearing protective equipment against hazardous chemicals. In 2022, we go all out to prevent related accidents through user risk prediction activities, such as conducting special safety training for handlers.

Air Pollutant Management
To reduce air pollutants generated by fossil fuels, SK bioscience controls emission of air pollution through management in the pre-planning stage, such as replacing boiler fuels with LNG. We regularly measure air pollutants and maintain and manage emissions below the standards.
Our L HOUSE uses eco-friendly refrigerants that minimize ozone-depleting substances generated during the operation of the refrigerator. In addition, to manage exhaust gas in the workplace, we measure the air quality when ventilating to maintain the percentage of the fresh air to 30% or more compared with the standards. By operating independent and local heating, ventilation, air conditioning(HVAC) equipment to control indoor pollutants and block their introduction. Overall, we thoroughly protect the indoor air quality in the workplace and employees’ health.

Water Pollutant Management
SK bioscience’s water resources management minimizes wastewater generation and reduces water consumption. First, we utilize the Biokill system to reduce the risk of water pollution effectively. We try to reduce contamination during discharge by removing biological hazards that may arise from the process, and by controlling the pH level before discharge through pretreatment facilities.
Also, we monitor monthly wastewater discharge and establish measures to reduce usage. In 2022, to accurately identify the causes of wastewater generation, we plan to install an additional wastewater meter to monitor the figures for each source and establish and manage discharge targets through careful management.
To reduce water consumption, we recycle factory water and identify various ways to consume treated wastewater. Also, we use the rainwater collected in our tanks at L HOUSE and manage the water through conservation planning.
