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.

Resource and Waste Management
GC strives to manage resources and waste according to the concept of circular economy, which places emphasis on maximizing resource efficiency. This initiative begins in the product development stage, in which GC minimizes waste by exchanging leftover products, feedstock, and fuels from production between plants to create added value. GC also raises awareness among all concerned parties, both internal and external, by applying the concept of circular economy and expanding towards a green culture and green resource and waste management, employing the 5Rs (Reduce, Reuse, Recycle, Refuse, Renewable) to reduce waste and maximize resource efficiency across the value chain, and ultimately achieve the goal of zero industrial waste to landfill. These initiatives have been carried out since 2015 and are still ongoing. Waste and wastewater are also recovered and processed for reuse. Moreover, GC has continuously implemented the Green Turnaround Management Project, in which measures have been established to prevent and reduce environmental impacts resulting from the maintenance of machinery and equipment. For example, GC began treating wastewater generating from the cleaning of equipment and machinery during a turnaround in its plants to reduce the amount of waste disposal by incineration. and began reducing the landfilling of non-hazardous waste and municipal waste by processing them into Refuse Derived Fuels (RDFs), thus maximizing their use. GC also cooperated with employees in each area of operation in assessing and sorting non-hazardous waste and municipal waste that could be reused as fuels as well as separating waste generated in production and from offices by type and delivering it to waste disposers who re-utilized it as fuels.
More information on other highlight projects is available in GC Integrated Sustainability Report 2022, such as
- Refuse Derived Fuel: RDF to reduce the amount of waste for landfill disposal and maximize waste reutilization through collaboration with employees.
- Strengthening the organization’s environmental culture by urging employees to participate in tree planting and waste separation activities on important occasions, such as the World Environment Day (June 5, 2022) and Thai Environment Day (December 4, 2022) which correspond to 5Rs concept and can recycle 9.72 tons of waste.
