Abstract
A screening of Life Cycle Assessment for the evaluation of the damage arising from the production of 1 kg of
recycled Polyethylene Terephthalate (RPET) fibre-based panel for building heat insulation was carried out according
to the ISO 14040:2006 and 14044:2006. All data used were collected on site based on observations during
site visits, review of documents and interviews with technical personnel and management. These data were
processed by using SimaPro 7.3.3, accessing the Ecoinvent v.2.2 database and using the Impact 2002+ method.
The study showed damage to be equal to 0.000299 points mostly due to the: 1) PET thermo-bonding fibre supply
fromChina bymeans of a freight-equipped intercontinental aircraft; 2) production of bottle-grade granulate PET;
3) mediumvoltage electricity consumption during the manufacturing of RPET fibre panel. Itwas also highlighted
that there were environmental benefits due to recycling through mainly avoiding significant emissions and reduced
resource consumption. An improvement assessment was carried out to find solutions aimed at reducing
the damage coming from the most impacting phases. Furthermore, the environmental impacts due to the production
of the analysed RPET fibre-based panelwere compared to other materials with the same insulating function,
such as polystyrene foam, rockwool and cork slab. Finally, the environmental benefits of the recycling of PET
