Emissions of formaldehyde and VOC from wood-based panels
2009
Athanassiasdou, Eleftheria | Ohlmeyer, Martin
Indoor air quality and product emissions from building products have become a subject to broad public concern in recent years. Emissions from wood products in buildings and constructions may cover formaldehyde and volatile organic compounds (VOC). - Formaldehyde originates mainly from the urea formaldehyde aminoplastic resins, which are used in the production of wood based panels (e.g. particleboard, fibreboard, plywood) used in furniture, flooring, wall partitions and ceilings. The chapter presents the formaldehyde emission property of wood-based panels and its evolution during the last decades, in connection with the evolution of the related international standards and regulations as weil as the efforts devoted to formaldehyde emission limitation. - For another group of emissions, the volatile organic compounds, new testing and evaluation methods are under consideration with respect to the Construction Products Directive. The chapter also discusses the approaches as well as the experience with wood products carried out so far.
