GC One Report 2023 [EN]

Waste Management GC has applied the principles of circular economy in formulating our Waste Management Policy. We also focus on minimizing the amount of waste in tandem with implementing the 5Rs principles, which consist of Reduce, Reuse, Recycle, Renewable and Refuse. Furthermore, we have developed a system to monitor and prevent impacts that may occur on communities, society and environment across the value chain in order to ensure that waste is being managed according to the company’s requirements and in strict compliance with laws and international standards. In 2023, GC achieved the Zero Industrial Waste to Landfill and Zero Waste to Landfill goals for the ninth consecutive year. GC has also executed a variety of waste management projects, such as Refuse Derived Fuel (RDF), Green Turnaround, which includes subprojects such as Reutilization of Insulation, which can effectively lower resource consumption and minimize hazardous and non-hazardous waste from turnaround activities. As a result of our continuous efforts in waste management. Organization Transformation GC strives to become the chemical industry’s leader in organizational efficiency as well as a top quartile employer in Asia-Pacific (APAC). The company has developed the 2023-2027 Organization Transformation Strategy, which highlights the importance of four core aspects of management, namely Skills & Competencies, Resource Planning, Great Well-being, and Policy & System Transformation. This enables GC’s strategy to accommodate business volatility and competition in the long run. Skills & Competencies GC has modified the method of employees’ skill and ability development training from offering basic content for employees in all business units to contents that are more critical and specific for each unit. The company has also improved the training method using an experiential learning approach through hands-on practice. Accordingly, each business unit considers and analyzes business strategies and define skill development guidelines that are consistent with shortterm, medium-term, and long-term strategies, with support and advice from internal and third-party experts in order to create a competitive advantage.
