We keep paying attention to the issue of improving the efficiency of energy use. Therefore, we continue to replace old energy-consuming equipment, and through various energy management measures, achieve the synergy of energy saving and carbon reduction.
Energy policies:
In addition to urging all employees to turn off the lights, the General Affairs Department makes monthly statistics and announcements on the electricity and paper consumption of each floor of the company’s headquarters in that month, showing the efficiency results by comparing with the same period in the previous year, and discussing possible energy consumption and assisting in providing energy-saving methods, to implement energy conservation and carbon reduction in all aspects of daily operations. The main energy efficiency measures implemented by the company headquarters in 2022 were as follows:
In order to reduce the possible environmental impact during the construction of the construction site, we abide by the relevant environmental protection laws and regulations of the central and local authorities, and have established the “Environmental Management and Maintenance Standards for Engineering Projects” for strict control. In view of the temporary pollution that may be caused by each construction site, our main environmental protection improvement countermeasures and preventive measures are as follows:
Noise Control
Water and soil pollution prevention and control
Protect water resources at the construction sites
Construction pollution and control over drainage at construction sites and pollutants during pavement construction. We set up overflow protection facilities and intercepting ditches to reduce the overflow of pollution sources. We strictly control the water resources at construction sites, and the supervisors of each construction site shall implement the following items:
Air pollution prevention and control
The Environmental Protection Administration tightened air pollution control regulations for construction projects from November 1, 2022. The construction sites of a certain scale are required to be equipped with an air quality monitoring system. We have taken relevant preventive measures in advance and installed monitoring systems at construction sites across the country for prompt, effective control over construction operation with the purpose of complying with laws and regulations and strengthening self-management capabilities.
Measures on Air pollution prevention and control
Waste management
The waste generated from our operation activities includes domestic waste from employees, construction waste, and remaining earthwork, etc. The waste is treated according to different categories as follows:
Domestic waste
Domestic waste generated by employees at the company’s headquarters and construction sites is classified and recycled in accordance with environmental protection laws and regulations, and the promotion of waste reduction and classification is strengthened by posting posters and other means. Public work offices across the country have comprehensively carried out waste classification, kitchen waste recycling, and other materials recycling. All waste is entrusted to qualified private and public agencies for waste removal and disposal in accordance with the law for clearance, transport, and disposal.
Construction and soil waste
Construction waste and building demolition residues generated at construction site are entrusted to qualified recycling organizations for removal and disposal, after we collect reusable resources such as metals, plastics, and wood as much as possible. Reusable waste is sort out in processing factories through the further procedures of manual primary selection and electromagnetic separation.As for the treatment of construction surplus earthwork, early in the planning stage of the construction project Kedge Construction prioritizes the design for the earthwork balance with no earth transported outward at a construction site, or reduce the transportation of earthwork through the earth exchange between construction sites. For earth that is difficult to recycle and reuse, the Procurement department will entrust a professional contractor approved by the owner to sign a contract for excavation, sludge disposal and backfilling. All of earthwork will be transported to the legally established waste disposal site or earthwork resource storage sites in accordance with the regulations of the construction management unit.
In addition, in order to promote the recycling and reuse of construction waste, we collaborated with Kindom Development and MINIWIZ and recycle waste materials such as falling prevention nets, adhesive films, and canvases from construction sites for the first time to make double-wall waterproof boards. With the Erchongpu construction project as a demonstration target, we will be gradually expanded such methods to different construction projects in the future.
We have an Occupational Safety Office, responsible for the supervision of environmental protection related to construction projects, and it assigns environmental protection personnel to be responsible for relevant affairs in each construction project according to laws and regulations. The personnel must participate in the regular/irregular environmental protection publicity meetings or the education and training sessions organized by the environmental protection agency of the local government concerning construction projects. Regarding the investment and use of major equipment for environmental pollution prevention and control for construction projects, the key points of pollution prevention that generate possible benefits are as follows:
Since each construction project is subcontracted to professional contractors approved by the owner, pollution prevention equipment such as fences at construction site (2.4m high for the first-level construction site; 1.8m high for the second-level construction site), overflow prevention facilities, dust-proof nets, rented water tanks for roads cleaning, vehicle washing stations, high-pressure vehicle washing machines, intercepting ditches, water collection wells, sedimentation tanks, temporary toilets, high-floor garbage pipelines, waste dumps and other facilities are also handled by the subcontractors themselves. Our Occupational Safety Office (environmental and health team) will send personnel to perform regular/irregular check-up on each construction project. If any deficiencies are found, immediate improvement is required. Therefore, there is no need to install or purchase special equipment to prevent environmental pollution.
