Sofia has recently completed an MSc in Psychology of Economic Life at the LSE. She holds a BSc in Psychology with Organisational Psychology and Behavioural Economics from City University, London. She is interested in how to develop sustainable business models, services and products, by leveraging on psychosocial dynamics that do not leave a footprint on the planet. Her research analyses domestic everyday life, including resource consumption habits, with particular focus on energy and water. The scope of this project is to zoom in on the household context to understand the psychology of waste under the light of Installation Theory. In order to do so, everyday life is analysed with the help of three interacting layers, namely material, embodied, and social. Wasteful practices resulted to be mainly energy and water related and derive from physical and social stimuli (objects and people) interacting with less visible psychological factors (embodied habits and experiences). This study hopes to stimulate research in finding opportunities of improvement to make householders’ life easier and more sustainable for the planet.
