In this work, we formulate and solve a multi-objective stochastic optimisation problem that allows explicit trade-offs under uncertainty, maximising system efficiency and minimising deployment cost. We use the yield after spillage (YAS) approach to incorporate the physical and operational constraints and the big-M method to reformulate the nonlinear minmax rules of this approach as a mixed-integer linear programming (MILP) problem. By posing a risk averseness measure on efficiency as a conditional value at risk (CVaR) formulation, we guarantee the designer against the highest demand and driest weather conditions. We then exploit the lexicographic method to effectively solve the multi-objective stochastic problem as a sequence of equivalent single-objective problems. A detailed case study of a botanical garden in Amsterdam demonstrates the framework’s practical application; we show significant improvements in system efficiency of up to 15.5% and 28.9% in the driest scenarios under risk-neutral and risk-averse conditions, respectively, compared to deterministic approaches.

This study addresses these gaps by employing System Dynamics Modelling (SDM) to capture a more nuanced understanding of the heterogeneity of decommissioned panels.

The former showed high selectivity and extractive performance for most of the heavy REEs (>95 %) by using the HDEHP ligand (1.0 mol/L) and adjusting the acid concentration of the aqueous solution at 0.01 mol/L with hydrochloric acid. The developed extractive metallurgy process was applied to doped REE cellulose fibers after performing a digestion, showing impressive extraction profiles in most cases (>80 %).

It assesses supply chain risk (two stages: mining, processing) and economic importance for twelve materials representing infrastructure, battery, specialty, and other materials.

The EU and Japan exhibit higher supply risks overall than both the US and China, largely because of limited domestic production capacities. Japan has the highest number of materials—eight out of twelve—with both high supply risk and economic importance. Materials with the greatest difference in criticality among regions are rare-earths and aluminum at the processing stage, where processing bottlenecks and concentration of processing facilities heighten supply risks, and lithium, nickel, and cobalt at the mining stage, due to geographic concentration of mining activities and rising demand driven by battery production.

The review found that changing attitudes and behaviour towards the optimal use of PwRC is influenced by psychological factors, although economic and sociological factors do also have an impact. Of these psychological factors, attitude, knowledge, perceived behaviour control, and subjective norms are more frequently examined. From the economic factors, economic benefits and from sociological factors, collaboration and communication are the primary considerations. The review also suggests that the theory of Planned Behaviour and the Extended Theory of Planned Behaviour are the most widely used theories in this respect.
