Meeting new, more strict limits for formaldehyde emission from wood based composites is hardly possible without essential changes in technology and processing. Since modifications of amino resins occurred to be not enough, other approaches must be considered. Thus, the present studies regard analysis of formaldehyde levels in raw materials for particleboard production at the beginning of processing chain: (1) chips from wood yard and (2) wet particles collected after knife ring flaker. The obtained results allowed to determine contribution of formaldehyde emission from wood material to overall emission from particleboard and to define procedures minimizing formaldehyde emission from the products in future.
