To minimize environmental impacts throughout construction processes, Kedge Construction actively adheres to central and local government environmental regulations. Company headquarters and all engineering projects have comprehensively implemented ISO 14001 Environmental Management Systems, committed to reducing environmental impacts across all project phases. Kedge Construction pursues environmental sustainability goals while actively assuming global environmental protection responsibilities, working to mitigate climate change impacts and achieve mutual prosperity through environmental coexistence.

Kedge Construction’s Environmental Policy

Environmental Protection Measures

For environmental protection throughout engineering project construction phases, Kedge Construction established comprehensive “Engineering Project Environmental Management and Maintenance Standards” to rigorously control potential temporary pollution impacts. Primary environmental improvement strategies and preventive measures include:

Noise Control

  • Manage construction personnel, work schedules, construction methodologies, equipment selection, and facility operations.
  • Develop noise prevention measures across different construction phases including site preparation, excavation and transport, foundation work, construction, and finishing activities: implementing electric power systems replacing diesel generation, engine electrification, hydraulic lifting equipment utilization, full casing and reverse circulation cast-in-place or precast pile construction methods, hydraulic or precision cutting demolition techniques, and avoiding simultaneous high-noise machinery operations.
  • Implement equipment noise prevention and regular maintenance programs, installing acoustic enclosures for noise-generating components (such as engines) with fire-rated sound-absorbing materials within enclosures; for construction equipment generating vibration noise, install vibration damping pads or springs (such as rubber cushioning) beneath machinery bases.
  • Adhere to noise control zone regulated operating hours, avoiding holiday or nighttime construction while minimizing continuous operation durations.

Soil and Water Pollution Prevention

  • Install comprehensive systems including vehicle wash stations, high-pressure cleaning equipment, sedimentation basins, spill containment systems, weather protection facilities, and interceptor channels. Vehicle washing equipment must be positioned at designated fixed locations within construction sites.
  • Construction wastewater requires filtration treatment prior to discharge with regular sedimentation pond water quality monitoring.
  • Bentonite fluids from earth retention operations undergo site personnel supervision ensuring contractor proper recovery and regulatory-compliant processing.
  • Concrete operation washwater and foundation excavation stabilizing fluids require sedimentation and filtration prior to discharge authorization.
  • Domestic sewage utilizes septic tank systems with qualified treatment institution commissioning for regular removal and processing, preventing soil infiltration contamination. Outdoor waste storage requires covering to prevent sewage overflow and soil seepage contamination.
  • Construction site and surrounding drainage systems receive covering or filter screen installation with regular cleaning and maintenance protocols.
  •  Equip construction access roads with appropriate covering and drainage facilities to prevent erosion.
  • Adhere to water and soil conservation regulations when working near rivers, and employ low-pollution construction methods with adequate water pollution control equipment to minimize river water pollution.
  • Regularly maintain construction vehicles and equipment to prevent oil leaks. Prohibit changing liquid oils such as engine oil and lubricants within the construction area, and perform maintenance exclusively at off-site vehicle service stations.
  • Prohibit cleaning paint tools in sedimentation barrels or tanks.

Air Pollution Control

  • To reduce dust dispersion, appropriate height fences are installed around the construction site.
  • Deploy air quality monitoring systems enabling immediate implementation of effective control measures when emission thresholds are exceeded.
  • For construction sites exceeding 10,000 square meters in area or external soil and stone volumes (loose measurement) exceeding 10,000 cubic meters, install monitoring instrumentation and video surveillance systems for air pollution prevention facilities.
  • Exposed surfaces within the construction site are sprayed with water, covered with dust nets, or paved with concrete or gravel to reduce dust dispersion.
  • For vehicle pathways within the construction sites, steel plates or concrete are laid to suppress dust spread.
  • Vehicles, bodies, and wheels leaving the construction site are cleaned.
  • Vehicles transporting dispersible particulate pollutants utilize enclosed cargo containers or securely covered cargo systems. When utilizing dust-prevention cloth or mesh covers, edges must extend at least 15 centimeters below cargo container upper edges.
  • Install dust-prevention cloth/mesh systems along structural scaffolding perimeters or building structures.
  • Prioritize equipment featuring “Clean Emission SelfManagement Certification” ensuring optimal diesel engine construction equipment exhaust system performance while reducing black smoke emissions.

Waste Management

Waste streams generated through Kedge Construction operations encompass employee domestic waste, construction waste materials, and surplus earth and stone. To enhance resource utilization efficiency while reducing environmental pollution from waste generation, headquarters facilities and nationwide construction sites have comprehensively implemented waste classification protocols, mandating 100% industrial waste processing through Environmental Protection Administrationapproved removal and treatment operators for recycling, reuse, and incineration disposal, achieving zero waste landfill volumes and 100% waste transfer rates. Processing protocols by category include:

Household Waste

Garbage from the company headquarters and construction site employees is sorted and recycled according to legal regulations. Posters and other methods are used to promote waste reduction and sorting. All regional offices across the country have implemented sorting, food waste recycling, and resource recycling. Waste is cleared and processed by qualified public or private waste disposal agencies as mandated by law.

Construction Waste and Excess Soil and Rocks

Construction debris and building demolition materials generated at construction sites undergo resource separation procedures to maximize collection of reusable materials including metals, plastics, and wood, with remaining construction mixtures commissioned to qualified reuse institutions for removal and processing. Treatment facilities implement manual sorting, electromagnetic separation, and air classification procedures to categorize reusable resource materials. Construction surplus earth and stone management prioritizes soil balance within work zones or inter-site exchange between nearby construction projects, with remaining materials transported to legally established waste treatment facilities or earth and stone resource storage sites per regulatory requirements.

Compliance with Environmental Regulations

Kedge Construction conducts biannual legal assessment operations while providing timely updates and announcements of critical regulations, supporting engineering projects in confirming regulatory applicability and proactively addressing current requirements. Engineering projects designate personnel responsible for environmental protection affairs, requiring participation in environmental advocacy and educational training programs organized by local government environmental protection agencies with project jurisdiction.

Through December 2024, comprehensive review encompassed 19 environmental regulation categories including environmental protection, atmospheric environment, water quality protection, resource circulation, environmental management, chemical substance management, climate change, plus owner and additional requirements, totaling 362 regulations. Site-specific applicability assessments address marine and agricultural water conservation laws based on varying engineering characteristics and locations.

Environmental Operations and Educational Training

  • All pollution prevention equipment and environmental protection measures implement regulatory compliance and owner special requirement provisions as operational standards, with immediate corrective action for identified deficiencies.
  • Engineering project coordination assigns designated personnel to execute environmental protection responsibilities per regulatory and company system requirements, including regular on-site self-inspection and compliance evaluation, audit result documentation and reporting, coordinating personnel for non-conformance improvement initiatives, and emergency support for complaint/violation incident management.
  • Periodic environmental protection training and educational programs include government sponsored environmental protection lectures to strengthen environmental awareness among employees and collaborative vendor personnel while implementing construction environmental protection practices.
  • Educational training delivery includes ISO 14001 regulatory assessment practice, environmental risk assessment practice, and internal audit practice across 5 sessions, training over 100 participants.
  • Four environmental education series lectures encompassed “Effortless Energy Conservation,”
  •  “Climate Change Kitchen Workshop,” “Urban Hydrology Green Spaces and Sustainable Environmental Value,” and “Experiencing Community Warmth: Second-hand Value Innovation for Sustainable Living,” with over 300 participants.
  • Participation in multiple briefing sessions organized by environmental protection bureaus across Taipei City, New Taipei City, Taoyuan City, Miaoli County, and Taichung City addressing construction engineering environmental regulations, construction equipment certification standards, and air quality health impact education.
  • Regular cleaning and maintenance operations around construction sites ensure environmental cleanliness standards.
