Summary A comprehensive life cycle assessment of panels for aircraft interiors was conducted, including both a conventional glass fiber-reinforced panel and different novel sustainable panels. The conventional panel is made of a glass fiber-reinforced thermoset composite with halogenated flame retardant, whilst the sustainable panels are made of renewable or recyclable polymers, natural fiber reinforcements and non-halogenated flame retardants.Four different sustainable panels were investigated: a geopolymer based panel, a linseed oilbased biopolymer panel, and two thermoplastic panels, one with polypropylene (PP) and another with polylactic acid (PLA). All the sustainable panels were developed to fulfil fire resistance requirements and to be lighter than the conventional panels in order to reduce fuel consumption and air pollutant emissions from the aircraft. The environmental impacts associated with energy consumption and air emissions were assessed, as well as other

The life cycle assessment (LCA) methodology was used to calculate the environmental impacts of the current chemical pre-treatment with chromium (VI) for electroplating acrylonitrile butadiene styrene (ABS). The inventory comprised: the procurement of chemicals; the manufacturing process with successive baths and rinses that requires, in addition to chemicals, energy to heat baths, air agitation, filtration, and so forth, wastewater treatment and air emissions; and also the treatment of sludges from wastewater treatment and exhausted baths. Chromic acid was almost the unique responsible of eco-toxicity (97.5%) and human toxicity-cancer (99.8%) and it was one of the highest contributor to climate change, cumulative energy demand, fossil fuel depletion, human toxicity non-cancer, and in abiotic depletion.
