Introduction
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 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 life, 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
polystyrene (PS) recyclates intended for use in the production of semi-finished/finished products.
