1. Scope
1.1 This guide provides an approach for both the calculation and the substantiation of recycled content of finished packag- ing paper and paperboard products. Amass balance approach is recommended for use by manufacturers since no physical or chemical test method is currently available to determine absolute recycled content of a finished paper product. Calcu- lations are based on time weighted average flows which are based on furnish component flow rates and consistency. Rec- ommended approaches to the calculations include by batch or by time weighted average for a specific grade or similar grades. It is not recommended that average recycle content be allocated by mathematical apportionment rather than by actual fiber content. That is, if 50 % recycled fiber is used over time that is the time weighted average. One cannot use this same data to report 50 % of the production is 100 % recycled. 1.1.1 Percentage calculations are based on lb/ton or kg/ tonne with the time frame constrained by machine and grade (see 10.1.1.1 and 10.1.1.2). 1.1.2 Pulping and recycling yields are not used in these calculations. The calculations of recycled fiber content in the finished product is solely a function of type of fibers in the furnish flows, the volume of flow and the time period consid- ered. 1.2 This guide covers (1) recycled content of packaging paper and paperboard products that contain any amount or kind of recycled fiber; and (2) methods to calculate and substantiate the level(s) of recycled fiber content claimed by an agreement between the buyer and the seller. 1.2.1 This guide may be used with or without modification to calculate or substantiate the recycled content of packaging paper and paperboard products when recovered nonfibrous materials (for example, filler) are a part of the recycled fiber furnish. Limited guidance is provided for appropriate modifi-cations to this guide for the determination of amount of recycled nonfibrous materials in paper products. 1.3 This guide does not recommend either an amount or a kind of recycled fiber or material to use since (1) the amount and kind of recycled content in a packaging paper or paper- board product should be agreed upon between the buyer and the seller, and (2) the calculation and substantiation procedures recommended may be used for any amount or kind of recycled material agreed upon between the buyer and the seller. 1.4 The mass balance calculation method recommended by this guide may or may not comply with applicable federal, state, or local laws for recycled content statements intended to be received by consumers. Limited guidance on content statements is in Appendix X1. 1.5 The following safety hazards caveat pertains only to the test method portion, Section 10, of this guide: This standard does not purport to address all ofthe safety concerns, ifany, associated with its use. It is the responsibility ofthe user ofthis standard to establish appropriate safety, health, and environ- mental practices and determine the applicability ofregulatory limitations prior to use. 1.6 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
6. Composition
6.1 Recycled content of packaging paper and paperboard products supplied in accordance with this guide should be agreed upon between the buyer and the seller (see 5.1). 6.2 The average recycled content for a packaging paper or paperboard product shipped from the seller to the buyer within a specified time period (see 10.1.1 through 10.1.1.3) should be at least equal to the contracted recycled content or be within a degree of variation (see 6.3) of that content. 6.3 The buyer and the seller may agree to a degree of variation in the recycled content in shipped product from the seller to the buyer when multiple shipments will take place over the contract period; however, any degree of variation for recycled content greater than 10 % is not recommended. In addition, recycled content of a shipment of product that exceeds the degree of variation agreed upon by the buyer and the seller should be reported by the seller to the buyer in an agreed-upon manner. 6.4 Recycled content of packaging products composed of two or more components should be reported as the weighted mean recycled content of the multiple components (see 10.2). 6.5 All measures ofrecycled content should be on an air dry or conditioned weight basis as specified by the buyer (see 5.1.2).
