Comparative cradle-to-gate LCA approach of PA, PLA and PP reinforced with CFs, CNTs & GNPs filaments (IRES)

  • Climate change, fresh water & Marine eutrophication, Freshwater ecotoxicity, Land use and Mineral fossil & ren. Resource depletion impact categories were selected as the most affected among others.
  • CF, CNTs & GNPs production has a clear environmental hotspot over the composite filament production processes.
  • Reinforced PA has the highest environmental impact on climate change independently of the type of reinforcement due to the fossil fuel origin production and the related emissions to air, water and soil.
  • PA, PLA and PP with GNPs present higher environmental impact compared to the other reinforcements in fresh water eutrophication, marine eutrophication and land use.
  • PA, PLA and PP with CNTs mainly affect the fresh water ecotoxicity.
  • The majority of the developed composite filaments have a high impact on Mineral eutrophication and Fossil & renewable resource depletion.
  • Accounting for all impact categories and assuming equal weight, PP with 3% CFs filament seems to be the most preferable option based on the decision making process through the LCA approach.
