Abstract
Due to the increasing global production of wood based panels (particleboards, fiberboards, and plywood) problems with raw material and difficult treatment of recovered wood based panels after life cycle occur. Inorganic pollutants represent the main problem of raw material while treatment of recovered wood-based composites is aggravated due to the presence of synthetic adhesives. Latter and the release of methane during anaerobic decomposition are reasons for using alternative methods instead of sending these composites to landfills. The most promising methods of recovered wood-based panels treatment are: hydrothermal recycling, re-manufacturing of panels, combustion and pyrolysis, composting, re-use and some other less used methods for processing of new recycled products.

Title:Treatment of recovered wood-based panels
Abstract:
Zaradi vse večje svetovne proizvodnje lesnih ploščnih kompozitov (iverne, vlaknene in furnirne plošče) prihaja do težav, povezanih z vhodno surovino in vprašanja ravnanja z odsluženimi lesnimi ploščnimi kompoziti po koncu življenjske dobe. Največje omejitve pri vhodni surovini predstavlja vsebnost anorganskih onesnažil, ravnanje z odsluženimi lesnimi kompoziti pa otežuje prisotnost sintetičnih lepil. Zaradi le-teh ter sproščanja metana med anaerobnim razkrojem na deponijah se države izogibajo odlaganju na odlagališčih in se poslužujejo drugih metod. Med najobetavnejšimi rešitvami so: recikliranje lesnih ploščnih kompozitov s pomočjo hidrotermične obdelave, ponovna izdelava plošč iz reciklirane surovine, sežiganje in piroliza, kompostiranje, ponovna uporaba ter še nekaj redkeje uporabljenih metod za predelavo lesnih kompozitov v reciklirane produkte.
