Joris’ research spans the areas of sustainable energy and environment, with a particular focus on developing life cycle assessment (LCA) methodology for circular economy strategies of electric vehicle batteries. Joris holds two master’s degrees from UCL, having worked with LCA for project NOMAD – an EU Horizon 2020 project exploring emerging technology for the circular bioeconomy. Joris is a 2021 Alumni of the Ellen MacArthur Foundations’ “From Linear to Circular” programme, Founder & Trustee at Editors for Impact, a past contributing writer at Degrees of Change, and has led the largest Engineers Without Borders branch at UCL. Joris plans to secure leadership positions in EU policy, think tanks or research institutes on a mission to secure an environmentally sustainable, socially just and economically thriving society.

Outside of work, Joris advocates for physical and mental health with a passion for martial arts, mindfulness, philosophy, and a plant-based lifestyle. Joris enjoys nature and the outdoors, playing classical guitar, and his most simple morning pleasure - freshly ground coffee beans!

Advanced Life Cycle Assessment of Circular Economy Strategies for Electric Vehicle Batteries

By 2030, the global EV stock is rising to surpass 145 million. While EVs powered by renewable energy aims to address the climate emergency, the environmental impacts of Li-ion batteries across their life cycle pose a threat to the sustainability agenda. Batteries not only have high upfront impacts for carbon footprint and resource depletion but there is rising concern over their end-of-life collection and recyclability, with an estimated 21 million Li-ion battery packs to reach their end-of-life between 2015-2040. Therefore, circular economy strategies to repurpose, remanufacture and recycle batteries is critical for maximising battery material lifespan to minimise their life cycle environmental impacts.

This PhD project will develop Life Cycle Assessment (LCA) methodology for circular economy strategies of EV batteries to quantify environmental metrics and determine their potential meeting the 2030 and 2050 sustainability agendas. The LCA work will utilise the latest tools such as Brightway2 (Python) and explore multiple scenarios such as EV synergies with renewable energy strategies, battery second-life applications in energy storage, and end-of-life recycling.
