“…WPCs have lower environmental impacts than unfilled plastics but higher than solid wood or most other wood composites. Use of sustainably harvested and recovered wood products in long-life products sequesters atmospheric carbon and can produce a positive environmental impact (Hill et al 2015).…”

Bark as a biowaste has a huge availability throughout the world and has had limited use in industrial applications. Black pine bark and oak bark were considered in this work. The aim was to manufacture a new biocomposite with different combination of black pine bark, oak bark, polypropylene, polyethylene, and a coupling agent, and to determine some physical and mechanical properties of the manufactured biocomposites. Density, thickness swelling, water absorption, tension strength, modulus of rapture and modulus of elasticity in bending and tension of the biocomposites were determined. According to the results, thickness swelling and water absorption properties were improved up to 80% when compared with wood-plastic composites (WPC) produced with wood flour. Although the new biocomposites displayed lower mechanical performance in comparison of biocomposites made with wood flour, the observed results were satisfactory. Based on the results of this study, black pine bark and oak bark can be used as filler materials in WPCs production. Hereby, these bark materials can be the raw material for value-added products. Bark use in biocomposite production also can contribute to reduced requirements of wood material and petroleum products.

“…LCA addresses both the entire life cycle of a product and a comprehensive range of environmental impacts, resulting in the avoidance of problem shifting, for example, from one life cycle stage to another or from one environmental compartment to another. LCA has been applied to different types of bio-based building materials, such as modified wood (Ferreira et al, 2016;Hill and Norton, 2014), wood-based panels (Rivela et al, 2005;Werner and Richter, 2007;Wilson, 2009;dos Santos et al, 2014;Silva et al, 2013Silva et al, , 2014, corkboards (Sierra-Pérez et al, 2016) and materials based on agricultural (Ardente et al, 2008;Silva et al, 2014) and animal resources (Murphy and Norton, 2008). Nowadays, there are also several EPDs focusing on bio-based building materials.…”

“…Petroleum-derived formaldehyde-based adhesives are still the most widely used adhesives for various types of wood-based composites, especially in particleboard and medium density fibreboards [ 9 ]. However, stringent environmental and human health safety regulations, as well as increasing raw material costs, have prompted researchers to minimize the amount of hazardous substances and/or costly adhesive components in finished products and to replace conventional adhesives with more environmentally friendly and safer alternatives [ 7 , 10 , 11 ]. The use of formaldehyde-free bio-based adhesives, which do not substantially raise manufacturing costs while resulting in wood-based composites with suitable properties, is one of the most innovative “green” solutions to address this issue [ 12 – 15 ].…”
