“…Based on Table 2, some studies consider the cascaded use of waste (e.g., cascading of wood), having as an end the extension of the life cycle and reduction of waste disposal [37]. The wood waste can also make it to the production process of wood particle panels or fiber panels [37], reaching 40% of the use of recycled wood [38]. However, according to Table 2, there are "reuse" practices, which aim at the recovery of products with several possibilities of use.…”

Circular Economy Practices on Wood Panels: A Bibliographic Analysis

et al. 2019

The scarcity of natural resources and the generation of waste without adequate disposal are a worldwide concern related to the linear production model.These characteristics are present in the wood panel production. Faced with this problem, the present study aimed to identify in the literature, circular economy (CE) practices in the waste management of wood panel production processes and the possibilities for implementing new practices that incorporate circularity concepts. A systematic search was conducted to select the most relevant work on the theme. A search was done using the ScienceDirect, Web of Science, and Scopus databases by combining the following keywords: “Circular Economy” (and its possible variations), “Wood-based Panel”, and “Wood Waste”. The results evidenced circular economy practices on waste management already being used by the wood panel industry, besides potential practices to increase circularity. The changes go towards sustainable manufacturing and responsible consumption, which aims to “ensure sustainable consumption and production patterns”. Opportunities range from the extraction of raw materials to the disposal of wood panel waste at the end-of-life. The circular economy model is still recent and the process of transitioning is in its initial phase, as well as scientific research on the theme, mainly regarding the wood panel industry. Studies addressing the circular economy and wood panels are not yet widespread, pointing to a gap yet to be explored. The bibliographic review allowed identifying the existence of potential applications of circular economy in the wood panel industry; yet, this piece of research points to a broad field of exploration.

“…Abreu, Mendes and Silva [35] developed small decoration objects from wood panel reuse, such as OSB, MDP, and MDF, thereby avoiding the inadequate disposal of such panels. Moreover, according to Garcia and Hora [38], 25% of wood waste can be utilized in reuse scenarios.…”

“…By means of an optimized sorting and treatment of wood, the complete amount of waste wood (in categories A I and AII) could potentially be returned to the market for material recycling. This is about 50-80% of the German market volume in 2015 (Fehrenbach et al 2016;Garcia, Hora 2017) and would allow to meet up to 50% the fibre demand for derived timber products from recovered wood. However, only a smaller fraction of about 13 to 20 % of waste wood is used for material recycling (Mantau 2013;Sommerhuber et al 2015;Garcia, Hora 2017), and an even smaller fraction of approximately 6% in multiple-stage cascades (Höglmeier 2015).…”

Another reason for the rather low material recycling is the fact that until recently, it was financially more attractive to sell waste wood (AI and A II) for energy recovery.…”

Aim: As the traditional approach towards entering a path of sustainabe development based on a „efficiency, consistency, sufficiency aproach“ is questionable, This article discusses opportunities and challenges for the circular economy to become a „last chance“ fort he current capitaist system to become more sustainable.Design / Research methods: Two case studies of material (waste) streams of plastics and wood-waste are presented in order to identify challenges in the development and functioning of the circular economy. Conclusions / findings: While the circular economy can deal with threats to sustainability embraced in an efficiency and sufficiency approach, it refers to a technology-driven consistency approach, not questioning the consumption and production patterns in the capitalist economy, and the functioning of the market economy as such.

“…The undoubted advantage of using wood is that due to the relatively low combustion temperature (up to 1200 K [13]), when it is burned, much less (approximately 5 times) of oxides of nitrogen and sulfur are formed than in the oxidation of coal [14]. It should also be noted that woodworking industry waste can be used as raw material for fuel production based on wood biomass [15], the volumes of which are large.…”

The results of the experimental and theoretical studies of the processes of the single particles ignition of the wood biomass of various forms (a cube, a cylinder and a sphere) have been presented. According to the results of the experimental studies, it has been established that the particles form can have a fairly significant effect on the characteristics and conditions of ignition. It has been shown that the wood particles in the form of a sphere are ignited much faster than cylindrical and cubic ones (ignition delay times are less by 56%). Such a tendency is maintained for particles sizes from 1 $ 10 À3 m to 3 $ 10 À3 m. According to the results of the experiments, the mathematical model for ignition of a particle of wet wood biomass has been formulated, taking into account the joint occurrence of the main processes of the thermal preparation (radiation-convective particle heating, evaporation of water, thermal decomposition of the organic part of the fuel, output, ignition and combustion of gaseous pyrolysis products, ignition of the char residue). The formulated system of the nonlinear differential equations in the partial derivatives with the corresponding boundary conditions describes the ignition process in a two-dimensional setting, taking into account the substantial nonuniformity of the temperature field of a wood particle in the induction period. We have taken into account that the evaporation process takes place in the front. Up to the present time, the mathematical models of such a degree of detailing of the physical processes occurring together when igniting wet wood have not been formulated. A comparative analysis of the ignition delay times (t ign) obtained theoretically and experimentally has showed their satisfactory correspondence. As a result of the numerical simulation, the temperature fields in the system "a fuel particle d hightemperature medium" have been obtained, illustrating the high gradients of the temperatures at the moment of ignition. It has been established that it is possible to ignite the water-saturated wood particles before they dry completely. It has been established that the ignition mode of wood particles is possible before they dry completely.
