Environmental Performance

We engage mainly in factory assembly and R&D in office setting that are free of any high energy consuming activities. Our operations consume principally water and electricity, while the consumption of other resources, including gasoline and diesel for cars and natural gas for cafeteria cooking amounts to less than 10% of water and electricity consumption. Thus our energy conservation efforts focus on the reduction of water and electricity consumption as described below:

Electricity Conservation

  • Zone power control: Each production line in the plant is installed with a meter to control the air conditioning, lighting, and power use in the zone. The same power control scheme is used for public chiller room and nitrogen air compressor room.
  • Lighting adjustment: The lighting throughout the plant is checked to determine the required luminosity, and extra light tubes in office area and public area are removed to save electricity.
  • Adjusting the outlet water temperature of chiller: We have adjusted the outlet water temperature of chiller to 7 degree from 6.5 degree.
  • Onsite control of air conditioners: User units would carry out onsite control of air conditioner to avoid unnecessary waste resulting from the uniform setting of temperature. The thermostatic and hydrostatic areas in the warehouse are reduced in view of the use situation.
  • Installing split-type air conditioners in some R&D areas: As air conditioning system is not required in some R&D areas after the staff has left for the day, the chillers in those areas are turned off after work.
  • Changing the method of central air conditioning system control: Currently blower coil pipes of the central air conditioning system are separately controlled with a three-speed switch. We plan to switch to the use of temperature controller.
  • Cutting down the working hours of air handling unit of the air conditioning system in some areas.
  • Installing solar panel and solar water heater in some areas of the plant.

Water Conservation

  • Mobile water pumps: Use collected rainwater for landscape watering.
  • Stepped-up patrol inspection: Increase the patrol inspection of water systems to reduce water loss.
  • Recycling and reutilization plan: The MSI Shenzhen began to experiment with water recycling in 2009. The project is still in trial operation and not fully implemented yet.

Fuel Oil Conservation

  • Controlling the opening hours of boiler in living area: Use IC card to control the use of hot water so as to reduce the use of fuel oil.
  • Air compressor heat recovery system: The heat generated by the air compressor is recycled for heating to reduce the use of fuel oil.

Waste Management

We engage mainly in the assembly of electronic products. Thus the solid waste we mainly generate including IC tray, tin slag, waste plastic, mixed metals and waste paper. IT tray, tin slag, waste plastic, waste paper and mixed metals are processed and recycled by professional waste hauler, whereas general waste, including daily refuse are collected by the water hauler and hauled to incinerator or landfill for disposal. Hazardous waste, including waste light tubes, gloves with oil smudge, waste battery, and waste solvents are collected by the waste hauler and then buried or treated in other manners.
