Fire performance of carbonized medium density fiberboard manufactured at different temperatures

Solid wastes from furniture industries require proper disposal and may have potential to be used as input in other production chains. The aim of the current study is to assess the use of medium density fiberboard (MDF) to produce bio-oil and carbon black with low emission of toxic elements. A full factorial design was used to assess 27 bio-oil preparation procedures based on the acid digestion of MDF shavings. The influence of three concentrated acid types (HNO3, H2SO4 and HCl) at three different temperatures (25, 75 and 150°C) and digestion times (30, 60 and 90min) was assessed. The contents of Al, Ba, Cd, Cr, Cu, Ni and Pb samples were determined through ICP OES. The Al and Ba contents oscillated between 442.2 ± 235.9 mg kg-1 and 17.9 ± 8.6 mg kg-1, respectively. The Cd, Cr, Ni and Pb contents were below the detection limit set by the technique. The tests showed that the studied material has the potential to be used as bio-oil and carbon black with low emission of metallic elements; thus, it was considered a potential alternative source of biomass-generated energy and, in parallel, it provides the furniture sector with an additional waste management option

Fire Properties

Poultry is a crucial global protein source.However, processing creates sizable quantities of feathers as a by-product. Identifying suitable uses for these feathers poses a major challenge. One possible use would be as an extender in medium density fiberboards (MDF). At the same time, feathers might also modify the inherent fire resistance of the resulting panels, suggesting the need for additives to enhance fire performance. The potential for using feathers to supplement wood in MDF panels was evaluated in conjunction with the addition of wollastonite. The effects of using 5% or 10% feathers with or without 10% wollastonite were investigated. Adding 5% feathers did affect properties. However, simultaneous addition of 10% wollastonite resulted in panels with improved fire performance properties and increased the ability of panels to dissipate heat. The results suggest that feathers could be a resource for extending timber supplies for MDF production, especially with wollastonite to improve fire performance.
