1.1 本指南为制定减少屋顶覆盖物浪费的计划提供了信息。回收的屋顶覆盖物和任何废弃屋顶覆盖材料可重新加工成新的屋顶覆盖物、其他屋顶产品或屋顶以外的产品。本指南不对用于增加回收材料总量的其他回收材料的使用或包含进行评论。 1.2 本指南介绍了材料回收过程中的术语、物流、质量保证、分离或隔离。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本指南旨在通过启动屋顶覆盖物回收计划，供屋顶覆盖物制造商用于制定现场废物减少和资源回收协议。屋顶覆盖物应发送至可通过化学回收、机械回收或其他公认方法处理材料的设施，并运至屋顶覆盖物制造商，以纳入新屋顶覆盖物的生产。 另一种选择是将再加工材料发送给其他制造商或生产设施，以便将其纳入新产品中，而不是用于屋顶的材料。本指南不包括屋顶覆盖物垃圾焚烧发电。

1.1 This guide provides information for the development of a program to reduce roof covering waste. The recycled roof coverings and any scrap roof cover materials may be reprocessed back into new roof coverings, into other roofing products, or into products other than roofing. This guide does not comment on the use or the inclusion of other recycled or recovered materials which may be used to increase the total amount of recycle material. 1.2 This guide addresses terminology, logistics, quality assurance, separation, or segregation in the recycling process of materials. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This guide is intended to be used by roof covering manufacturers to develop protocol for waste reduction and resource recovery in the field, by initiating a recycling program of the roof covering. The roof coverings should be sent to a facility where the material can be processed by chemical recycling, mechanical recycling, or other accepted methods, and shipped to the roof covering manufacturer to be included into the production of new roof coverings. An alternative is to have the reprocessed material sent to other manufacturers or production facilities to be incorporated into new products aside from those used in roofing. This guide does not include roof cover waste to energy.
