GGC is aware that the industrial sector consumes more energy than other business sectors. Both the acquisition and consumption of energy may affect the environment and health. Furthermore, they contribute to climate change. Therefore, the Company is determined to solve this problem at the root cause by efficiently using energy to reduce impact on the environment and society throughout our value chain.

Goals

Limit energy consumption to not exceed
2.9727
megawatt-hours per ton of production in 2021.

Energy Management Operational Guidelines

All GGC factories are certified with the ISO 50001 energy management standard. Energy efficiency have been improved and controlled in every process by strictly complying with standards, laws and requirements.

Furthermore, the Company has also taken steps to conserve and manage energy under various projects, such as:

Project to Reduce the Use of Steam in the Methanol Purification Process

GGC has finalized the project to reduce the use of steam in methanol purification process in 2020 by modifying the filter pattern in the distillation tower from the Tray Structure to the Pack Structure that can help reduce steam consumption and reflux of the Methanol Purification Column. This can reduce steam energy consumption by 1.30 tons per hour.

Water Quality Improvement in Steam Production Project

GGC has improved the quality of water used in steam production. The raw water used for steam production is purified through Reverse Osmosis (RO) to reduce energy loss from high temperature effluent discharge from high chloride raw water. The project can reduce wastewater discharge and energy loss as well as decrease the use of fuel oil for heating raw water by 25 liters per hour.
