GHG Reduction Initiatives
GC has introduced numerous projects that reduce greenhouse gas emissions (scope 1 and 2) in order to lessen climate change impact with focus on three aspects, namely 1) energy conservation and energy efficiency enhancement, 2) use of clean energy, such as alternative energy and combined power generation in tandem with implementation of carbon capture technology, and 3) application of new technology, such as hydrogen, etc.
In addition, GC has invested in the development of energy storage technology using high-performance battery. This initiative will play an important role in enhancing the capacity of clean energy technology. Accordingly, GC has invested in ESS inc., which is listed on the New York Stock Exchange (NYSE) under the ticker symbol GWH.
Energy Conservation and Enhancement on Energy Efficiency Projects
Installation of Gas Turbine Generator and Heat Recovery Steam Generator at Utilities Plant
GC has carried out a project to enhance the overall efficiency of the utilities plant (U-P1). The project uses new machinery with enhanced efficiency to reduce fuel consumption and lower CO2 emissions rate from the use of fuel in power generation.

Clean Energy Projects
Maptaphut Integration (MTPi)
GC has conducted the Maptaphut Integration (MTPi) Project to maximize the efficiency of energy and utilities management. Furthermore, it features integrated waste management that helps to reduce loss during transportation, decrease greenhouse gas emissions and manage waste utilization with effectiveness.
One of the project’s goals is encouraging the use of alternative energy, which is in line with the principles of circular economy and GC’s sustainability guidelines in dealing with the changing global context and climate. As a result, various projects were conceived, including Floating Solar Panels and Solar Rooftops. An installation plan for each area is clearly determined based on the conditions and timeframe agreed upon with the contract parties. At present, GC has installed solar rooftops in 14 plants and 3 offices, yielding a cumulative production capacity of 19 megawatts. The Solar Rooftop Project began in 2020 and will be completed in 2027. Meanwhile, the Floating Solar Panels Project will be finalized in 2022.
New Technology Projects
Development of Model to Control the Reactor in the Production Process
GC has upgraded the efficiency of technology in its production process and cut down CO2 emissions by studying, developing and applying advance analysis technology to build a model that controls the reactor in the production process in a suitable condition. This has resulted in higher production output while requiring less reactants and energy. Moreover, it contributes to lowering CO2 emissions. GC plans to conduct further studies and extend this project to other production processes.

Study and Development of Using Membrane Technology for Organic Solvent Separation
GC has studied and developed membrane technology to replace the use of organic solvent distillation in the Aromatics production process. This will help to reduce energy consumption in the production process and decrease CO2 emissions. GC plans to further apply such technology to other production units.

Online Chemical Cleaning for Convection Coil of Fired Heaters
Innovation has been applied to the process of cleaning fired heaters; offline cleaning has been replaced with online cleaning using chemicals to clean up soot on the convection coil while the heater is in operation. As a result, GC has cut down energy consumption and produced more steam, helping to save up to 24 million baht per year in related expenses. In 2022, GC will expand the project which is expected to contribute to an additional cost-saving of approximately 30 million baht per year.

By-Product / Waste Upgrading
GC has studied and developed the use of appropriate technology to dispose of contaminants in waste and by-products from Olefins production process while maximizing their value. This has contributed to reducing CO2 emissions as a result of the lower amount of waste destined for disposal and the transformation of by-products into high-value chemicals. GC has further plans to apply this technology to other production units.
