Brightway’s inventory calculations usually rely on direct sparse solvers such as PARDISO or UMFPACK. These are robust and fast for many applications, but they can become a major bottleneck when technosphere systems grow very large. In particular, the matrix factorisation step can require far more memory than the sparse matrix itself, making calculations on large or dense systems painfully slow...

Land-based carbon sequestration strategies require linking soil carbon dynamics with supply chain responses, accounting for land-use effects and biomass valorization. This work develops a parametric modelling workflow in Brightway 2.5 for consequential LCA of soil carbon sequestration strategies (SCS) in French croplands. Life cycle inventories integrate soil organic carbon (SOC) trajectories...

Life-cycle assessments are rarely applied as often to the operational decision-making in production as to the planning stage, despite the significant cumulative environmental impacts of high-volume processes. The bottleneck here is that an LCA is too complex for daily use, and decision-makers in production are not trained to interpret the results.

For the ENCIRCLE project, parameterised...
