Introduction
Recycling 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 is 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 document 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 may occur
that could affect the product's suitability for recycling into the intended application.
1 Scope
This document specifies the main characteristics and associated test methods for assessing of
polyethylene (PE) recyclates intended for use in the production of semi-finished or finished products.

This document does not cover the characterization of plastics wastes, which is covered by the
EN 15347 series, neither traceability topics which are covered by EN 15343.

4 Symbols and abbreviations
For the purposes of this document, the symbols and abbreviations related to recyclates given in

5 Characterization of PE recyclates
A single batch is the quantity of PE recyclates that has homogeneous characteristics within the specified
tolerances.
PE recyclates (see EN ISO 1043-1) may be composed of:
— polymeric matrix, consisting of polyethylene (PE content);
— other polymers, compatible with the polymeric matrix;
— fillers, pigments and other additives.
— impurities or contamination in a quantity which do not compromise the workability characteristics
of PE recyclates;
The characteristics of PE recyclates, which shall be determined for every batch (see ISO 3534-2) of
recyclate, are given in Table 1, and are divided into two types:
a) required characteristics, needed to define PE recyclates in general, and required for all recyclates;
b) optional characteristics needed to define PE recyclates according to customer specifications and
applications.
NOTE Polyethylene plastics waste originates from different types or grades of PE containing additives to
modify characteristics. Polyethylene is generally classified as PE-HD (high density polyethylene), PE-LD (low
density polyethylene), PE-LLD (linear low-density polyethylene) and others of less common use. The properties and
performance of recyclates derived from such wastes can depend on the type or relative proportions of blends of PE,
but it is not in the scope of this document to investigate such relations.
These characteristics shall be assessed
