“…Currently, wood waste (WW) causes an important economic and environmental issue. Recently, the authors of References [2,3] have reported that the European Union generates more than 50 million m 3 of WW each year, and according to this data, the future potential of WW recycling is quite low, mainly lacking sustainable reuse or recycling applications, e.g., in the construction industry [4,5]. However, WW is highly biodegradable and easily attacked by microorganisms and insects, which shortens its service life.…”

Research of Wood Waste as a Potential Filler for Loose-Fill Building Insulation: Appropriate Selection and Incorporation into Polyurethane Biocomposite Foams

Currently, the recycling potential of wood waste (WW) is still limited, and in a resource efficiency approach, recycling WW in insulation materials, such as polyurethane (PUR), appears as an appropriate solution. It is known that the quality of WW is the main aspect which influences the stability of the final products. Therefore, the current study analyses different WW-based fillers as possible modifiers for polyurethane biocomposite foams for the application as loose-fill materials in building envelopes. During the study of WW-based fillers, it was determined that the most promising filler is wood scobs (WS) with a thermal conductivity of 0.0496 W/m·K, short-term water absorption by partial immersion—12.5 kg/m2, water vapour resistance—0.34 m2·h·Pa/mg and water vapour diffusion resistance factor—2.4. In order to evaluate the WS performance as a filler in PUR biocomposite foams, different ratios of PUR binder and WS filler (PURb/WS) were selected. It was found that a 0.40 PURb/WS ratio is insufficient for the appropriate wetting of WS filler while a 0.70 PURb/WS ratio produced PUR biocomposite foams with the most suitable performance: thermal conductivity reduced from 0.0523 to 0.0476 W/m·K, water absorption—from 5.6 to 1.3 kg/m2, while the compressive strength increased from 142 to 272 kPa and the tensile strength increased from 44 to 272 kPa.

“…Due to inner structure glulam elements have small weight and it helps to carry great seismic stresses. CTBUH supports ecobuilding and suggests that glulam will be widely used to make skyscrapers [13][14][15] not only in stable but also in seismically dangerous regions.…”

The main purpose of this research is to prove the efficiency of glulam to meet various architectural needs. The three features of glulam such as: plasticity and aesthetic value, functional efficiency, supporting properties and resistance to extreme conditions, are compared with the same features of concrete and steel, the most widely used materials nowadays. The methods are based upon actual test results and practical experience in creating glulam constructions. The research shows that plasticity of glulam allows to create complex curved surfaces and its surface and texture clearly demonstrate the unique aesthetic features of the elements made of this material. Glulam can also be efficiently used to create various space morphotypes such as compact rooms, linear vertical and horizontal space, hall space, space with a complex spatial configuration. It is also proved that glulam strength expressed in Constructive Quality Ratio (CQR) surpasses steel and concrete in supporting ability and its durability also exceeds steel structures durability and is comparable to concrete.

“…In this step, we sought to insert the equations and features of each tool in the modules to achieve the intended objectives. The equations entered in the system were according to the literature survey and data collection (TESSARO; SÁ; SCREMIN, 2012;SCREMIN;CASTILHOS JUNIOR;ROCHA, 2014;KERN et al, 2015;PAZ;LAFAYETTE, 2016;GULARTE et al, 2017;FONSECA;RIBEIRO JUNIOR, 2018;PAZ;LAFAYETTE;SOBRAL, 2018;LAFAYETTE et al, 2018;KERN et al, 2018;TEIXEIRA et al, 2020).…”

Knowledge of the qualitative and quantitative composition of waste is essentialin order to propose alternatives and strategies for construction and demolition waste (CDW) management. Tools to support the integrated management of CDW have been of great help in identifying the best management alternatives. This article aims to develop a computational system (software) which supports the integrated management of CDW for Brazilian municipalities. The software was divided into four stages: knowledge acquisition (data collection), system structuring (system tools), coding and validation, all based on a case study. In conclusion, the computational tool developed and tested with a robust database for managing CDW in municipalities makes it possible to identify better management alternatives, considering the different realities of each municipality and each construction project.
