Dynamic and On-Demand LCA (D-LCA)
D-LCA is an advanced Dynamic and On-Demand LCA module for environmental impact assessment. It is integrated into the PSM tool and performs life-cycle impact calculations from dynamically generated life-cycle inventories.
Operates as a computational layer on top of PSM.
Extracts time-dependent inflow and outflow data from PSM-modelled processes.
Supports Dynamic Process Inventories, Dynamic Systems and Dynamic Characterisation.
Uses configurable LCIA methods and characterisation factors.
Allows selection of functional units, system boundaries and impact categories.
Aggregates impacts per process, value chain and scenario.
Traceable outputs for hotspot identification, scenario comparison and environmental reporting.
The assessment begins with a defined goal, system boundary and functional unit. It requires the input and output flows of the PSM model and characterisation factors compatible with their units. Users select the environmental indicators to be calculated and can enter factors directly or import them through CSV or Excel. Time-dependent assessment also requires information on how the relevant flows change over the period being analysed.
The Dynamic LCA framework links environmental assessment with process modelling. Current work gathers and validates pilot information and aligns value-chain configurations with simulation models. Dynamic and On-Demand Life Cycle Assessment links environmental assessment to the resource flows represented in Process Simulation Modelling. Users first define the goal and scope of the assessment, including the system boundary and functional unit, and then connect the model's input and output flows with environmental characterisation data. The calculation workflow supports the selection of midpoint or endpoint indicators. Characterisation factors can be entered directly or imported through CSV and Excel files, with attention to unit conversion so that inventory flows and factors are compatible. Results can be expressed in the physical units of the selected impact indicators or through the corresponding aggregated assessment approach. The dynamic development considers changes in resource flows over time and extends the assessment perspective from individual processes towards connected value chains. When operating assumptions are changed in PSM, the linked assessment supports comparison of the resulting scenarios. This makes the service relevant to process designers and regional planners evaluating circular alternatives. The results remain specific to the model, inventory, factors and boundary used; a simulated improvement is not automatically a measured pilot outcome.
Complete pilot inventories and data validation; integrate the dynamic assessment workflow with the platform.
Functional unit, system boundary, material and energy inventory, transport, treatment routes, background datasets and scenario assumptions.
Life-cycle impact estimates and comparisons of hotspots and scenarios, with explicit methods and uncertainty. Live pilot integration is in progress.
Designed to exchange value-chain and simulation information with PSM and the regional platform; integration work is ongoing.
