The procurement of construction materials is an important step in WHA Group’s project development process. Therefore, the company has implemented sustainable procurement practices to ensure that no products are sourced from protected areas. WHA Group also emphasizes the selection of suppliers who can align with the concept of “Green Building,” as envisioned by the company in its construction projects. Furthermore, WHA Group supports the use of environmentally friendly materials and encourages contractors to choose materials that can be reused. This significantly helps in reducing construction waste. WHA Group prioritizes environmental care in accordance with its environmental quality policy, energy conservation, and biodiversity preservation. The company expects suppliers to adhere to these policies throughout the construction process, including regular project operations. The aim is to reduce resource consumption and implement environmentally friendly practices, as outlined in the supplier code of conduct, to minimize environmental impact.

Additionally, WHA Group promotes suppliers’ adherence to environmentally friendly practices. An example of this is the use of Plastic Column Formwork, a material that can be reused, reducing waste and debris from the construction process.

Furthermore, the design of buildings aligns with Leadership in Energy and Environmental Design (LEED) standards. The warehouse, constructed in alignment with LEED standards, has been executed as outlined below.
