Introduction

Recycling of plastics pre and post consumer waste is a material recovery process aiming to save

resources such as raw materials, water and energy, thus minimizing emissions into air, water and soil

and hence contributing to human health and environmental protection.

For a huge number of plastic products, individual recycling schemes have been established. Regarding

PVC windows and doors made of un-plasticized PVC, they are subject to an advanced recycling scheme,

i.e. a so-called controlled loop. In this particular case, the used windows and doors are collected, the

PVC frame separated, shredded and treated. The recyclate obtained therefrom then goes back to the

manufacturing of new window and door profiles. To ensure a high quality level of both plastic recycling

and finished products in a single market, the control of the recycling process is recommended to be

standardized, with regard to (i) process steps such as collection, identification, sorting, cleaning and (ii)

sub-process steps such as testing, quality assurance, and traceability.

In that respect, this document forms, together with EN 12608-1, and EN 14351-1, EN 14351-2 and

EN 16034 a unique and consistent standardization framework enabling the value chain to act in a

circular manner.

NOTE In this document, only EN 12608-1 will be mentioned. However, whenever this is the case

reference is made to all subsequent parts of EN 12608, once published as well.

This document defines quality and test methodologies for recycled PVC to be used in PVC window

profile systems.

It contains a description of the controlled loop as such, the definition of those material transformation

steps which are relevant for product quality, in particular recycling input and output and profile

manufacturing input and output.
Traceability tools are specified to characterize this loop as a controlled loop.

With regard to PVC waste treatment, the present document relates to existing standards such as

EN 15343, EN 15346 and EN 15347

With regard to semifinished and/or finished products, it refers to the European Standard for un-

plasticized PVC window profiles (see EN 12608-1) and to the European harmonized standard for

windows and doors (see EN 14351-1).

3.1
controlled loop
controlled loop of post-consumer PVC-U windows recycling

controlled process where end-user wastes, such as from windows and doors, are collected and recycled

4 Methodology, Procedures and Requirements
4.1 Controlled Loop Model and Life Cycle Stages

Life cycle stages as described in Introduction, Figure 1 refer to a linear model. Conceptually, when using

recycled PVC from stage D for the manufacturing of new PVC window profiles, the linear model turns

into a circular one and forms a controlled loop, as described in Figure 2.
Figure 2 — Controlled Loop, Life Cycle Stages and raw material input
4.2 Material Flow along the loop
4.2.1 Product stage A1 – A3 (stage I)

The loop shall start with product stage (A1 → A3), where raw materials are converted into finished

products. The product stage outlined here comprises first the manufacturing of PVC window profiles

and then their assembly to PVC windows, respectively PVC doors.

According to EN 12608-1, the raw material used for the profile production (extrusion) can be

characterized as follows:
— For visible surfaces:
— UV resistant virgin PVC-U compound respectively dryblend,
— Own re-processed PVC material, and
— For the non-visible surfaces:
— rPVC-U.

NOTE While incoming virgin PVC-U compound usually is ready to use, rPVC might have to be mixed with

additives such as fillers, pigments, stabilizers etc. to prepare a compound ready for extrusion.
