Life Cycle Assessment of Urea Formaldehyde Resin: Comparison by CML (2001), EDIP (1997) and USEtox (2008) Methods for Toxicological Impact Categories

摘要

This paper presents a Life Cycle Assessment comparison using CML (2001), EDIP (1997) and USETox (2008) methods for the impact assessment of urea formaldehyde resin (UF) used in the production of wood panels in Brazil. The impact results were focused just on toxicological categories like human toxicity and ecotoxicity. The main hotspots of UF resin were free formaldehyde air emissions to aquatic and terrestrial ecotoxicity and for human toxicity category, the results showed that emissions to air of nitrogen oxides from urea (raw material) are also very important and not just free formaldehyde air emissions like previously checked in literature.
