The polyester plant of FEPV implemented the Waste Treatment Manufactures Sustainability Leap Project to trace waste removed from the plant premise with precision, enhance supplier inspection efficiency and fulfill its due care obligation when commissioning waste disposal. The plant established a comprehensive supplier selection process, starting with a paper audit conducted by an inter-disciplinary team of procurement, waste management, environmental safety and legal staff. Credentials reviewed include company scale, risk assessments as well as permits and certificates. Site inspections are also conducted. Qualified suppliers must undergo weekly and monthly record review as well as quarterly and yearly site inspection in accordance with the Waste Treatment Supplier Review Program, which is a standard review system covering a checklist of 166 items under eight categories. The review checklist is updated yearly in response to regulatory changes and with annual review training provided. The suppliers are replaced annually based on Annual Waste Treatment Enterprise Evaluation.
