Ecological assessment of terrace decks; Part 1: Decks made of wood-polymer composites
Pages: 37 - 42
Small and medium-sized enterprises are challenged by fulfilling market demands for environmentally benign products, proven by transparent and reliable evaluation such as assessments based on a life cycle approach. In the assessment two different types of woodpolymer composites (WPC), differing in composition and geometry are compared. Functional unit is 1 m² covered terrace. Data sources are industry and the database ecoinvent (including transports). The impact assessment is done with CML 2001. The impact categories assessed are global warming potential, acidification potential, ozone depletion potential, photochemical ozone creation potential, and
eutrophication potential. Inventory shown is cumulated energy demand. Results show that in all impact categories materials provision and manufacturing are the key driver.
