Smart Operating
GC has adopted innovative technologies to design, develop and improve its production processes in order to align it with the principles of circular economy. By maximizing resource efficiency, utilizing renewable energy to mitigate the impacts of climate change, and stabilizing the production processes in the past year, GC has developed of business operation in accordance to ‘smart operating’. This includes
Examples of the Energy Conservation Projects
Gas Turbine Generator and the Heat Recovery Steam Generator project to enhance the overall efficiency in electricity generation of Utilites Plant and lower fuel consumption in production.

Using Mercury waste from the Aromatics and Refinery plants as raw material for medical equipment production.
Promoting and encouraging employees to segregate waste in office, e.g. segregating plastic, glass, and paper waste for recycling and segregating food waste to be used as animal feed by the surrounding community, etc.
Installing Seawater Reverse Osmosis (SWRO) and Wastewater Reverse Osmosis (WWRO) systems to monitor and improve wastewater quality discharged from wastewater treatment system to ensure that the discharged amount can be used and reentered in the operating process.
Reusing off gas from Aromatics Plants, i.e. ethane, propane, butane, as substrate for olefins plants instead of flaring for over 157,000 tons per year.
To utilize Fine polymer as recycle raw materials in manufacturing. This results in reduce consumption of Styrene monomer as a raw material in manufacturing process, and increase yield for more than 96%.
Increase Tail Gas value as raw material for Crackling Heaters and Oleflex Heaters at the Olefins Plant, which can reduce a flare loss of up to 648,000 Nm3
