Introduction
Recycling of plastics waste is one type of material recovery process intended to save resources (virgin
raw materials, water, energy), while minimizing harmful emissions into air, water and soil as well as
their impacts on human health. The environmental impact of recycling should 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:
— the 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;
— the 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 for 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.
This document is intended to serve two purposes.
1. To provide a guide to plastic recyclers and others that enables a calculation to be made of the risk
of inaccuracy presented by a chosen sampling regime. This will help to inform decisions about
sampling that can also be influenced by factors such as the supply record of a supplier or the
reliability of a process. This is covered in Clause 5.
2. To define the sampling procedures to be followed to characterize the material being sampled.
These procedures may be followed where a particular level of accuracy is required, or where the
sampling is in support of the resolution of a dispute. This is covered in Clause 7 and Annex A.
It is not the intention of this document to develop new sampling methods.
1 Scope
This document specifies a system for sampling procedures for testing plastics waste and recyclates
which take into account the specifics of the plastics waste and recyclates. It is intended to cover all
stages of the plastic recycling process.
The sampling procedures include the statistical specifics of the plastic waste and the behaviour of
recyclates.
The sampling method is expected to produce a representative testing sample. Differences can arise due
to:
— the mixture of plastics;
— the origin (e.g. green dot in Germany, or electronic/automotive industry);
— the previous use of the plastic material;
— the residual contents (e.g. of containers);
— inert, residual or moisture content on or in the material.
This document is without prejudice to any existing legislation.
