Final Report Summary - ECODISM (Ecological and economical development of innovative strategy and process for clean maintenance and dismantling further recycling of vehicle parts)

The purpose of the project was to propose to car manufacturers and automotive suppliers innovative technologies and methodologies based on smart bonding and de-bonding techniques that would be integrated at design stage of new vehicles in order to facilitate maintenance and dismantling operations for materials as plastic, composites, glazing metals and aluminum bonded parts in vehicles. Developed systems would have a duration life and chemical stability over 15 years. In this goal, the project consortium defined the following sub-objectives:
- Design active systems that could be integrated in adhesive systems for the several applications.
-Formulation of the chemicals according to the type of active systems, the elements to bond and the targeted stability and durability.
- Assembly line compatibility of the adhesives at the industrial scale.
- Selection and optimisation of the suitable energy source and methods to bring energy to the bonded assembly. Different energy sources would be considered.
- Computer modeling and optimisation of the debonding process.
- Definition of a dismantling protocol for further maintenance, reuse or recycling of vehicle parts.

The final objectives of the project were the following:
- Setting efficient maintenance and dismantling protocols in order to reach the ELV directive objectives.
- The ELV directive would impose a maximum ASR weight of 5%.

The main work items and achievements of the project consisted in:
- Understanding of the behavior and conditions of efficiency of adhesive primer modified with Thermo-Expendable Microspheres. First cases studied were with glass primer, but adhesive for other types of materials were also considered. Stability of the modified primers was assessed, as well as durability of bonded joints. Efficiency of the debonding effect was validated according to methodology developed within the project.
- Understanding of the behavior and conditions of efficiency of chemical agent as active system in modified primers or adhesives. Stability of these systems was also studied as well as durability of the bonded joints.
- Assessment of the feasibility of the application of modified primer or adhesive systems in industrial conditions.
- Studies of different type of energy sources, assessment of their performance regarding different types of materials to be bonded. Different systems were developed to perform the trials. Energy delivery was modeled.
- Life Cycle Analysis and Life Cycle Cost study was launched to assess the benefits of the technologies studied in the project.
- Dismantling process was studied in order to integrate the technologies developed in the project in an optimized ELV treatment scheme.
