This standard provides the general requirements for synthetic leather industry to have cleaner production on the basis of meeting the national and local environmental standards and in line with the existing technological, equipment and managerial levels of this industry. This standard includes three levels, the first level represents the international advanced level of cleaner production, the second represents domestic advanced level of cleaner production, and the third represents domestic basic level of cleaner production. This standard shall be amended every three or five years along with the technological development. This standard provides the general requirements for cleaner production of the synthetic leather industry. This standard classifies the indicators for cleaner production into five kinds, that is, requirements for production techniques and equipment, indicator for the use of resources and energy, pollutant indicator (prior to the end-of-pipe treatment), indicator for waste recycling, and environmental management requirements. This standard shall apply to the assessment of cleaner production of the synthetic leather (the raw materials being polyurethane, excluding ) producers, the estimation of the potential and chance of cleaner production, the performance assessment of cleaner production and the performance disclosure system for cleaner production, as well as environmental management systems like environmental impact assessment and pollutant discharge permit.
