Introduction
This document covers plastic products and components used in the vehicles falling under the scope of
the European Directive on End-of-Life Vehicles (ELV Directive) (2000/53/EC) and the European
Directive on motor vehicle reusability, recyclability and recoverability (Type 3R Directive)
(2005/64/EC).
The usage of plastics in vehicles’ components has grown to answer sustainability and fuel-efficiency
requirements mandated by national and international legislations and driven internally by many
industry stakeholders, to a point where, in absolute terms, plastics became a targeted material for specific
waste management recovery operations. The recommendations in this document aim at increasing the
recyclability of plastics used in vehicles and the recycling rates from end-of-life vehicles, considering that,
on average, plastics account for 14 % to 18 % [1] of the overall weight (1200 kg on average) of Type M1
vehicles.
Manufacturers are required by Union law to place on the market vehicles that are at least 85 % reusable
and recyclable and 95 % recoverable [2] [3]. For the recycling of plastic waste these targets lag behind.
This can be explained by high technical requirements for plastic automotive parts, which can lead to
specifications that make those plastics more challenging to recycle. Notwithstanding existing technical
and performance constraints, this document provides automotive engineers with design
recommendations to enhance the recyclability of the plastic products and components when the vehicle
reaches its end-of-life, hence maximizing the recovery rate and the value of the plastics fraction after the
vehicle's shredding, in line with the sustainability requirements stemming from existing and upcoming
EU legislation [4].
Due to the diversity of infrastructure across European ELV recycling facilities and the variety of end-of-
life scenarios, a vehicle designed today could be recycled in ten or fifteen years at a facility equipped with
the bare minimum tooling systems or at a large-scale state-of-the-art shredding and post shredder
recycling facility.
When implemented, these recommendations can ensure that materials specified on new vehicles can be
efficiently recycled using available post shredder technology infrastructure.
The post shredder technologies are an interesting option for recycling more of the plastics used in
vehicles. However, these technologies deserve to be better known by designers, as they require
implications for the design of parts. For a better understanding of the post shredder technologies, see
Annex A.
