BS EN 15348 is the European standard that gives guidelines for the characterization of poly(ethylene terephthalate) (PET) recyclates.

It gives the most important characteristics and associated test methods for assessing PET recyclates intended to be used for the production of semi-finished/finished products. It is intended for use by the supplier and purchaser of such materials, to assist them in agreeing on specifications.

BS EN 15348 is applicable without prejudice to any existing legislation.

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 standard has been produced in accordance with the guidance produced by CEN on Environmental Aspects and in accordance with CEN/TR 15353 Plastics. Recycled Plastics. Guidelines for the development of standards relating to recycled plastics.

CEN/TR 15353 considers the general environmental aspects that 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 throughout its life. Consequently, products are out of industrial control for a period of time. During this period, contamination with other materials may occur that could affect the product's suitability for recycling into the intended application.
