D6.1 Life cycle assessment and recycling options of Fatigue4Light solutions - Abstract

Fatigue4Light project aims at developing lightweighting solutions to show the benefits of EVs (BEV, HEV and pHEV) in material and energy consumption as well as environmental and economic impact, preserving fatigue and general performance of chassis parts.

In this report, Objective number 10 of the project by conducting a Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) for all chassis parts demonstrators. In addition, recycling solutions are also studied.

General methodological aspects of LCA and LCC methodologies are adjusted to be applied on the demonstrators including all life cycle stages of a vehicle from cradle-to-cradle.

LCA results for all demonstrators prove Fatigue4Light solutions as more beneficial solutions from an environmental point of view. As expected, use stage is the most dominant stage from an environmental point of view and lighter solutions have lesser energy consumption during the use stage. Regardless of the manufacturing and assembly stage, use stage is of great relevance for BEV, HEV and pHEV options.

Economic assessment also proves Fatigue4Light solutions as more economically efficient. Although hybrid solutions are still at lab scale and therefore less efficient than any other solution, even when compared to the other Lab-demonstrators.
