Aircraft Maintenance

Under compliance with corporate environment management mechanisms of international standards ISO 14001 and ISO 50001, CAL pays attention to details of daily aircraft maintenance operations. Energy saving and environmental friendly applications can be spotted throughout our operation processes.

Through promoting energy management systems, CAL oversees major energy plans. In conjunction with the company's carbon reduction targets, annual performance targets were established and executed. Key highlight measures are as follows:

  • Modified scrapped fuel vehicles to electric vehicles, saving machinery equipment and energy expenditure.
  • Improved operations environment. For example, light grey epoxy was used to paint the hanger floor to enhance the lighting effect.
  • Continued to promote replacing energy saving lighting equipment, installing automatic lighting controls, and adopting behavior management, among other energy saving measures.

Optimized process flow, inspected and controlled water-saving opportunities, and introduced conservation technologies. For example, the environmental aircraft cleaning program (ECOSHINE) was introduced in 2016 to perform aircraft cleaning processes, reducing the use of water resources and cleaning agents.

Set up professional wastewater plants and dedicated organizations for handling waste electrolyte (containing heavy metals, such as chromium and cadmium) from electroplating processes during aircraft maintenance and cleaning processes, and domestic wastewater produced within the plant area. Wastewater from the maintenance park area has reached a 100% recycling target.
