GC to increase waste utilization when compared with 2022 and achieve

hazardous waste to landfill.

Challenges and Opportunities

Efficient resource consumption and reduced waste volume reflect an enhanced production process. GC’s production process has also contributed to reducing resource shortage risks, environmental impacts, and waste disposal costs.

Therefore, GC has established the policy to increase capability of waste management and implement projects to reduce the waste associated with the turnaround activities and business expansion. This includes GC’s Zero Waste to Landfill Project in 2012 which has achieved its goals since 2015. The company has also implemented the Circular Economy concept as an approach to expand its comprehensive waste management by applying innovation in recycling waste into value-added products to satisfy the needs of all relevant stakeholders. However, GC recognizes that waste management is an issue that requires the cooperation of all sectors. Thus, GC encourages all sectors, including the public, to become aware of the waste problem and to gain knowledge and understanding about the process of waste management, including waste collection, separation, recycling and utilizing resources to maximize its benefits.

Waste Management Process

GC is committed to its waste management policy, which covers the hazardous and non-hazardous waste, in order to use resource efficiently throughout the value chain and to minimize waste generation by adopting the 5Rs Principle, including Reduce, Reuse, Recycle, Renewable, and Reject. GC has set up a system for waste handling process i.e. sorting, storage, transportation and disposal to manage, monitor and prevent the impacts on community, society and environment. Additionally, GC focuses on enhancing the efficiency of resources usage, and limit wastes generation to be minimum in order to reduce waste from business activities to disposal.

Currently, wastes which may impact the environment from production, maintenance and other activities are managed with effective and efficient measures that are in line with international standards, and only waste processors who are certified by the Department of Industrial Works can receive wastes from GC. In addition, GC has annually reported details of waste to related government agencies in order to ensure that wastes are managed properly and strictly complied with laws and regulations.

GC focuses on the improvement of company’s waste management to be continuously effective. The overall performance can be summarized as the following;
