Introduction
Recycling of plastic 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. 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.
During their use phase, products are temporarily out of industrial control. Consequently, at the end user
stage, it is often impossible to trace back each individual product and whether it has been used correctly
through its life cycle.
1 Scope
This document specifies the main characteristics and associated test methods for assessing of
polypropylene (PP) recyclates intended for use in the production of semi-finished/finished products.
It is intended to support parties involved in the use of PP recyclates to agree on specifications for specific
and generic applications.
This document does not cover the characterization of plastic 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
EN ISO 1043-1 apply.
NOTE Additionally to the abbreviation “rPP”, ‘PP-R” or “R-PP” or “PP (REC)” are used as well.
5 Characterization of PP recyclates
A single batch is the quantity of recyclate that has homogenous characteristics within the specified
tolerances.
The characteristics of PP recyclates, which shall be determined for every batch of recyclate, are shown in
Table 1, and are divided into two types:
— Mandatory (M) characteristics needed to characterize PP recyclates in general and required for
specified recyclates.
— Optional (O) characteristics needed to characterize PP recyclates according to customer
specifications and applications.
NOTE Polypropylene, or polypropylene-containing plastics wastes can contain a variety of propylene polymers
such as homo- and co-polymers, and be with or without fillers, fire retardants etc. The properties and performance
of recyclates derived from such wastes will depend on the relative proportions of these components.
These characteristics shall be assessed by using the test methods given
