Assessment of product lifetime extension strategies through repair in the circular economy framework. Application to electrical and electronic equipment

Abstract

In the framework of the circular economy, repairability has been identified as a priority strategy to extend the useful lifetime of products, especially electrical and electronic products. In this context, this thesis analyses the repairability of small electrical and electronic appliances (specifically electronic water kettles) from a consumer’s perspective. First, current consumer practices and perceptions regarding the purchase, use, and willingness to replace or repair these products are identified through an online survey. Then, their ability to repair them is analysed through a self-guided workshop, which also identifies the preferred repair documentation format and the necessary information for repairs. Finally, a consumer-oriented decision model based on the Life Cycle Assessment methodology is proposed. This model allows consumers to choose the best end-of-life strategy (replace or repair) with the lowest environmental impact for this type of product, considering six variables that affect its life cycle.
