Persistent data gaps limit the quality of life cycle assessments (LCAs), which frequently rely on incomplete, outdated, or non-comparable process data. Digital product passports (DPPs), initially developed for supply chain traceability, regulatory compliance, and circular economy objectives, also hold potential to address long-standing data challenges in LCA. Based on 20 selected, publicly documented DPP initiatives assessed a...

Purpose The demand for mineral raw materials for the energy transition is expected to increase greatly in the coming years, raising concerns about the environmental impacts associated with their value chains. Prospective Life Cycle Assessment (pLCA) can be applied to explore such impacts under alternative future scenarios. However, pLCA studies in the mineral value chain often lack consistency, as they use different modelling...

This work presents the PULPO ( P ython‐based u ser‐defined l ifecycle p roduct o ptimization) framework, developed to efficiently integrate life cycle inventory (LCI) models into life cycle product optimization. Life cycle optimization (LCO), which has found interest in both the process systems engineering and life cycle assessment (LCA) communities, leverages LCA data to go beyond simple assessments of a limited number of alt...
