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.

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.
