BS ISO 22453:2021 pdf download – Exchange of information on rare earth elements in industrial wastes and end-of-life cycled products This document specifies methods of information exchange between waste handlers and recyclers for rare earth elements (REEs) contained in industrial waste and end-of-life (EOL) products. This document facilitates the efficient recycling of REEs so that dependency on mining can be reduced by promotion of REE recycling. This document also includes a generic life cycle of the REE recycling process. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

In this document, downstream operations refer to processes during the production stages such as machining, milling, chamfering, etc. SOURCE: ISO 22450:2020, 3.5, modified — “mining and milling operations” has been deleted from the definition and Note 1 to entry has been replaced.] 3.2 life cycle consecutive and interlinked stages of a product system, from raw material acquisition or generation from natural resources to final disposal [SOURCE: ISO 14040:2006, 3.1, modified — “of a product system” has been added.] 6 Labelling methods 6.1 General There are many different types of labelling methods, including barcodes and RFID. One-dimensional (1D) barcodes are simple and widely used for providing information for products. However, they can represent only a small amount of data. In comparison, two-dimensional (2D) barcodes and RFID can include lots of data. Therefore, this...
