5.9 Scheme Review

5.9.1 The purpose of reviewing the resource utilization design scheme is to review the scheme based on the resource utilization goals and resource allocation requirements of waste products. The technical measures in the design scheme should be reviewed to ensure that the expected requirements are met. The following requirements should be satisfied.

a) The design scheme meets the purpose, objectives, and benefits of resource utilization;

b) The design scheme meets the basic principles of resource utilization design;

c) The design meets the usage requirements;

d) The design scheme is consistent with the analysis results of the waste products;

e) The design scheme is consistent with the resource utilization assessment results;

f) The technical measures in the design scheme meet the expected requirements.

5.9.2 Based on the review results, the following actions shall be taken.

a) If the design proposal fails the review, the design should be continuously optimized based on the review results until the proposal meets the requirements of all parties;

b) Once the plan is approved, the recycling and processing of waste products should be strictly carried out in accordance with the plan to support customer or market demand. Production.

5.10 Resource Utilization and Treatment The processes involved in the resource utilization and treatment of waste products, including dismantling, testing, repair, and assembly, should be carried out in accordance with GB/T 32801. The provisions of GB/T 32803, GB/T 32804, GB/T 32805, GB/T 32806 and GB/T 35977 shall be implemented to ensure the effective utilization of resources. The products, components, and materials obtained meet customer or market demands.

6.1 Storage and Management of Design Schemes

6.1.1 It is advisable to establish a waste product information management system to collect basic information about waste products, including but not limited to product model, production date, etc. The system tracks and analyzes the entire process of dismantling, cleaning, testing, processing, and assembling used products, including factors such as service life, degree of damage, and material type. Data related to waste products should be collected to optimize resource utilization plans and improve resource recycling efficiency. An information storage system for resource utilization design plans should be established. manage.

6.1.2 It is advisable to establish an information-sharing mechanism to promote the flow of information among recyclers, manufacturers, the government, and the public, enhance transparency, and publish information regularly. The report on the resource utilization of waste products displays key information such as recycling volume, processing efficiency, and environmental impact.
