Build and maintain LCI / PCF data for non-chemical supply systems such as: Electricity and heat generation (regionally resolved), Fuels (gas, coal, biomass, hydrogen), Cement and construction materials, Metals and mining (e.g., steel, aluminum), Water, waste, and recycling systems, Logistics. Structure and manage databases that integrate these sectors into the core chemical LCI model. Define system boundaries, functional units, and allocation rules aligned with LCA standards.
