Purple background, white letter = system process White background, purple letter = unit process Product flow: Products entering from or leaving to another product system (ISO 14044. Whether you are dealing with a system process or a unit process is also indicated by the symbol before the process. System processes in the model graph are framed with a double line (left), unit processes are framed with one line (right). transport impacts, data from LIPASTO (a calculation system for traffic.
System Processes (LCI): unit for which input and output data are aggregated (an aggregated life cycle result saved as a process) production systems and have acknowledged the benefits of using LCA as a product. Unit Processes: smallest unit analysed for which input and output data are quantified. openLCA distinguishes two types of processes: Every process is defined by an output flow as a quantitative reference with the flow type “product flow”, which is either selected or created when creating a project. Ecoinvent 3 example (same computer & product system) openLCA 1. the product provided by ecoinvent, call the parameter e.g. You can also use the Nexus page to search for individual data sets, using a varietly of search criteria such as product, sector, age, time, or price of the data set or database. Processes are sets of interacting activities that transform inputs into outputs. You can enter a parameter for the connection to ecoinvent, i.e. The data sets are aligned as much as possible with the openLCA software, for example with a coherent, comprehensive set of elementary flows. In principle, such a life cycle model data set is exactly the same as a product system model in openLCA: it stores the life cycle model of a product (the. OpenLCA include completeness of the product system, deviation from. Hi Norbert, your question is explained in our PET bottle example Further fields within the ILCD structure that are not addressed by entry possibilities in.
