“…One of the hazardous substances produced in furniture waste combustion is isocyanate [44]. Figure 6 presents the spectra extracted from 3D charts and recorded at a temperature of approximately 533 K. As seen, the peaks assigned to isocyanate (2250 and 2285 cm -1 ) are noticeable [45].…”

In this study, the combustion behavior of raw waste wood from furniture and samples torrefied at temperatures of 473, 513, 553 and 593 K was investigated. TG-DTG analysis showed that the mass loss in the first stage of the process decreased with the temperature of torrefaction, whereas the temperature in the second stage increased. The influence of torrefaction and combustion parameters on greenhouse gas emissions were investigated by the FTIR technique. The characteristic combustion parameters were also determined. The ignition temperatures for the furniture wood waste and samples torrefied at 473, 513 and 553 K from 549 to 559 K, whereas that of the sample torrefied at 593 K was significantly higher (600 K). All samples were completely burnt at 813-843 K, after 29-35 min, depending on the torrefaction temperature. Kinetic parameters are determined using a two-step firstorder reaction. The activation energy value for the first stage increased with the increasing temperature of torrefaction, from 68 to 125 kJ mol -1 , whereas the temperature in the second stage decreased from 108 to 47 kJ mol -1 . A similar correlation was observed for the pre-exponential value A. In the case of the torrefied furniture wood waste at 593 K, the combustion process runs as a single first-order reaction. The calculated data were fitted to the experimental data very accurately (R 2 [ 0.9992 and standard deviation \6.7 %), and the kinetic model was correctly founded. The linear relationship between logA and E a provides a way to predict the kinetic parameters of the combustion process. Keywords

A review on research has been made regarding recent developments aiming at reducing the negative environmental impact (because sometimes it might be positive) derived from industrial manufacturing processes of lignocellulosic-derived products, from their utilization, and also from their disposal at the end of their life. The most common journals of the wood science and environmental fields have been screened and relevant papers on this topic are referred and commented. This paper covers mainly lignocellulosic-based products taken as materials. That is saying, materials of common use and that were made incorporating mostly raw materials from forest or agriculture plants. Examples of such products are particleboard, waferboard, MDF, OSB, plywood and lignocellulosic-plastic composites. Excluded from this review are utilizations of biomass for heat=energy production or its processing for chemicals (e.g., ethanol). Important issues for this paper are: lignocellulosic wastes and sub-products recycling, Wood preservation environmental issues, VOCVolatile Organic Compounds emissions, adhesion of wood and LCA -Life-Cycle Assessment of forest products.

“…Nevertheless, disposing of wMDF in landfills is no longer an acceptable solution because it consumes significant land space (Kharazipour and Kues 2007). In other cases, burning is also not an environmentally friendly solution as it releases dioxins, carbon dioxide, methane, and other pollutants that can harm the environment (Tatàno et al 2009). Therefore, the recycling of wMDFs is more benign than burning or landfilling does (Morris 2017).…”

The vast production of medium-density fiberboard (MDF) in the world is expected to generate a large quantity of waste MDF after its service life, which requires the recycling of waste MDF (wMDF). This work attempted to investigate the removal of cured urea-formaldehyde (UF) resins adhesive in wMDF using hydrolysis for a possible way of recycling wMDF. The wMDFs were fabricated with two kinds of recycled fibers (RFs): refiner recycled fibers (RRFs) and hammer mill recycled fibers (HRFs) from red and radiata pine. The wMDFs were also produced at different RFs contents, such as 0, 5, 10, 20, 30, 50, and 100%. The panels were then hydrolyzed with water and oxalic acid solution to remove the cured UF resins. The Kjeldahl method was applied to determine the nitrogen (N) content in the panel before and after hydrolysis. Regardless of the wood species and recycling process, the mass loss, pH, and formaldehyde liberation of wMDFs after hydrolysis were greater for oxalic acid than those in water, confirming a greater N content had been extracted by oxalic acid than water. The resin removal became greater as the RFs content increased. In addition, the resin removal was slightly greater in wMDFs made of HRFs than the RRFs. Moreover, red pine RFs gave higher resin removal than radiata pine. These results suggested that a proper combination of the recycling process and additives could make it possible to recycle wMDF panels in the future.Keywords: cured urea-formaldehyde, hydrolysis, medium-density fiberboard, oxalic acid, recycling
