“…The more wood is processed, the greater the volume of wood waste produced. However, wood waste or materials deemed waste during production processes can be managed to become useful byproducts, providing additional benefits [4]. It's essential to manage wood waste to prevent wastage and minimize negative environmental impacts.…”

The wood processing production system in its activities always produces waste in the form of husks or pieces of wood. The opportunity to control wood waste can be used to heat boilers as a substitute for fuel oil. This study on the use of wood waste was carried out to assess technical, economic and environmental aspects. An assessment of the technical aspect was carried out to see the efficiency of using wood waste compared to fuel oil. Financial aspects are an important consideration in utilizing wood waste, while environmental aspects. Studies show that diesel fuel consumption is higher than wood waste fuel consumption, however boiler efficiency is higher using oil fuel compared to wood waste fuel, namely 70%: 20%. Financial analysis using NPV shows that this wood waste fueled boiler is economically feasible. From environmental aspects, it is known that fuel consumption for one year for wood waste fuel produces CO2 emissions of 1,207.36 tons, which is lower than CO2 emissions from burning diesel which is 6,808.31 tons.

“…because of its high ash content, 15 and it contains considerably more nitrogen and sulfur than other wood material, which makes bark attractive for use, to a large extent, in biofuel production. 16 Nevertheless, Sette Jr et al 17 evaluated the incorporation potential of bark harvested from Eucalyptus urophylla and Schizolobium parahyba species for energy purposes to produce briquettes as an alternative, renewable energy source. According to their findings, the E. urophylla biomass revealed better physical characteristics and lower ash content than S. parahyba.…”

This review gives an overview of recent advances in research on the role of tree bark material in bark-cement bio-composites, and their potential as building insulation materials. Suberin and other bark extractives seem to be of great importance for the insulation properties of such composites. Bark is a readily available, biological raw material with unique properties and it has revealed promising results as a bio-insulation material, either alone or in mixtures with different matrices (cement, lime, resins, polymers, etc.). The thermal, mechanical, acoustic, and hygroscopic properties of these bark-insulating composites depend on several factors, primarily the type of tree bark, the density and mechanical strength of the bark, the density of the boards produced, and the ratio of bark material to the binder material used in the board production (cement, lime, resins, polymers, etc.). The size of granules and the thickness of the board produced seem to be factors with a lower impact on the properties of the bark-cement composites. A low proportion of bark fibers or particles (0.5-1%) in bark-cement composites has proven highly beneficial to their mechanical and thermal properties and ensures higher workability of the mixture. Different modification treatments of bark material should be investigated, with the aim of decreasing the bark extractives content, to improving the cement setting, decreasing the unstable hemicellulose components and their hygroscopic nature, improving the bark particles' durability in alkaline environments, and upgrading their adherence properties. As the demand for alternative, sustainable structural materials keeps rising, the cement-bark composites will undoubtedly keep attracting the attention of the scientific and industrial world.
