NORSUS researchers had several contributions to the LCM conference this week.
Hanne Lerche Raadal and Ingunn Saur Modahl presented results from the CCUS Øra cluster project where systems for carbon capture storage (CCS) and carbon capture use (CCU) are analysed and compared with their respective reference scenarios without capture. The results show that the CCU scenarios perform worse compared to the reference (no capture) and CCS scenarios because converting CO2 to fuel is very electricity intensive and ultimately leads to re-emitting the captured CO2-emissions. It gives more environmental benefit to use the renewable electricity to substitute fossil electricity generation. If still fuel production based on CCU is chosen, an important criterion should be to use renewable excess electricity that is not available for other purposes for the CCU fuel production process.
Anna Furberg, Kari-Anne Lyng and Hanne Lerche Raadal presented results from a cradle-to-grave comparative LCA of the environmental impacts associated with metal and carton food packaging in Norway. The results show that the relative climate change impact of metal and carton food packaging is clearly affected by the selected approach for modelling recycling and that a high circularity score is not necessarily accompanied by low environmental impacts.
Together with colleagues outside NORSUS, Lars Tellnes presented a paper about the so-called FutureBuilt ZERO method that refers to an updated and extended model for assessing the carbon footprint of buildings.
To presentasjoner dreide seg om Environmental Product Declarations (EPDs): Anne Rønning, sammen med Jane Anderson fra The Open University og Construction LCA, snakket om fordeler ved digitalisering av EPD for å redusere byggs livsløpspåvirkninger og standarders rolle i dette, og Fredrik Moltu Johnsen diskuterte verifiseringsprosessen for EPD.
Clara Valente and Synnøve Rubach presented how social LCA (S-LCA) and social organizational LCA (SOLCA) can be used to shape the business model of start-up companies that aim to be socially sustainable both related to their daily operations and value proposition.
