EN 15348:2014 (E) 4 Introduction Recycling of plastics waste is one type of material recovery process intended to save resources (virgin raw materials, water, and energy), while minimizing harmful emissions into air, water and soil as well as any impacts on human health. The environmental impact of recycling has to be assessed over the whole life cycle of the recycling system (from the waste generation point to the disposal of final residues). To ensure that recycling constitutes the best environmental option for treating the available waste, some prerequisites should preferably be met: — recycling scheme being contemplated should generate lower environmental impacts than alternative recovery options; — existing or potential market outlets should be identified that will secure a sustainable industrial recycling operation; — collection and sorting schemes should be properly designed to deliver recyclable plastics waste fractions fitting reasonably well with the available recycling technologies and with the (changing) needs of the identified market outlets, preferably at minimum costs to society. This European Standard has been produced in accordance with the guidance produced by CEN on Environmental Aspects and in accordance with CEN/TR 15353. NOTE CEN/TR 15353 considers the general environmental aspects which are specific to the recycling process. It is often impossible to trace back each individual product at the end user stage and to check whether the product has been used correctly through its life. Consequently products are out of industrial control for a period of time. It is possible that during this period contamination with other materials might occur that could affect the product's suitability for recycling into the intended application. SIST EN 15348:2015

It is intended for use by the supplier and purchaser of such materials, to assist them in agreeing on specifications. This European Standard is applicable without prejudice to any existing legislation. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

The characteristics of PET recyclates, which shall be met for every batch (see ISO 3534-2) of PET recyclate are shown in Table 1, and are divided into two types: — required characteristics needed to characterize PET recyclates in general and required for all recyclates; — optional characteristics needed to characterize PET recyclates according to customer specifications and applications. These characteristics shall be assessed by using the test methods given in Table 1 and detailed below. A Certificate of Analysis, providing the test results for each batch of recyclate shall be provided by the supplier to the purchaser upon request. The supplier shall provide the necessary information about the material composition of the recyclates, as specified by the purchaser or required by the applicable regulations. SIST EN 15348:2015
