Environmental Management

Policy and Management System

In order to understand about comprehensive and macroscopic environmental trends, and consider multifaced environmental issues as part of business activity, CTCI introduces ISO 14001:2015 environment management system, adopting integrated management to environmental factors. In practical execution, we incorporate it with ISO 45001:2018 occupational health and safety management system into the health, safety, and environmental (HSE) management system, so as to bring it into the Company's routine operations. The Company's HSE management system is applicable to the activities, products and services that the Company can either control or influence in design, procurement, construction, commissioning phases i.e. 100% of revenue collection. Moreover, the system is certified by a third-party.

Water Resources

Air Pollution

Construction site air pollution prevention measures

Land leveling and excavation operations

  • Formulating work plan in advance to minimize exposed land, back-fill quickly, pave, plant vegetation, and clean soil pollution. Taking pollution prevention measures
  • Daily sprinkling
  • Sprinkling using temporary automatic sprinkling systems or manual sprinkling
  • Avoiding secondary pollution from mud resulting from over-sprinkling.
  • Water supply and cost are taken into consideration for the sprinkling plan.
  • Covering soil mounds with dust gauzes.

Preventing dusting and protecting air quality.

Material and soil stacking

  • Setting up fences for stacking
  • Sprinkling to maintain moisture or covering with canvas when stacking in exposed or windy conditions
  • Waste soil is shipped to qualified disposal grounds, landfills, or processing grounds.

Preventing blowing dust and dust fall.

Sand blasting operation

  • Carried out in protection-equipped indoor conditions on principle
  • Sand on the sand blasting grounds is swept or sprinkled upon.
  • Protective equipment includes sprinklers, ventilation, and particulate control, with bag-type dust collectors installed when necessary.

Preventing air pollution and impact on health

Spray paint, paint, and solvents

  • Operated in indoor environments with control equipment
  • Not allowed to operate under unstable weather conditions
  • Installing ventilation and washing (using water or otherwise) equipment downwind of the operating location

Preventing effusion of VOCs and impact to health

Vehicular transportation and cleaning

  • Vehicles transporting construction materials or particulate waste are covered with canvas or other non-permeable material.
  • All vehicles and machinery must be hosed down in the washing pool before leaving construction sites to ensure cleanliness.
  • After loading, truck beds must be covered with tarpaulin and sealed.
  • When driving through a construction site, vehicles must follow construction site rules and the instructions of construction site managers.

Preventing blowing dust and dust fall

Open burning

  • No burning is allowed.
