Introduction

Recycling plastics waste, by mechanical recycling, 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 document 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 for recycled plastics.

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.

5 Characterization of PE recyclates

A single batch is the quantity of PE recyclate that has homogeneous characteristics within the specified

tolerances.

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 1 Polyethylene plastics waste originate from different types or grades of PE containing additives

tomodify characteristics. Polyethylene is generally classified as PE-HD (high density polyethylene), PE-LD

(lowdensity 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 by using the test methods given in Table 1. Where possible, the

supplier should provide information on the original applications.

A certificate of analysis giving the test results for each batch of recyclate shall be provided by the

supplier to the purchaser upon request.

To secure the legal use of the recyclate, the supplier shall provide the necessary information about the

material composition of the recyclate, as specified by the purchaser.
NOTE 2 In this document, PE (R) is composed of:
— polymeric matrix, consisting of polyethylene (PE content);
— fillers, pigments and additives;

— impurities or contamination in a quantity which do not compromise the workability characteristics of PE (R);

— polymers compatible with the polymeric matrix.
