Wood-plastic composites (WPCs) increase the range of applications of materials by creating new material solutions. As part of this research, PLA (polylactic acid)- and HDPE (high-density polyethylene)-based composites were manufactured. Softwood sawdust or conifer bark with different sizes (large...

In order to improve the power selection of the drive unit for the shredding machines, the authors determine the values of friction coefficients used in the cutting force models. These values consider the friction between steel and such wood-based materials as chipboard, MDF and OSB. The tests...

The influence of the impregnation process of pine wood (Pinus sylvestris L.) samples on the electrical resistance changes and the moisture-content measurement accuracy is presented in this paper. In this study, the resistances of impregnated and nonimpregnated green pine timber harvested from...

The state of the epidemic in Poland and the resulting restrictions caused serious disturbances in the economy. Entrepreneurs, conducting business in conditions of economic uncertainty and the threat of a crisis, are looking for various support tools, including adequate government programs. The...

An analysis of selected traits of typical supply of oak logs and a comparison of efficiency of their processing into flooring. The research was performed on typical supply of oak wood logs of WC02 class, diameter from 29 to 34 cm, measured in the middle of its length (full log length 2.3 m). Wood...

The paper analyzes the costs of production of wood sawdust briquettes, manufactured by the company Brykiet-Pol2, based in Goleszów in southern Poland. In addition, production technology, raw material sup-ply and distribution of the finished product were analyzed. The costs of producing one ton of...

In this article, we present the dataset of mills from 1880 and 1920s-1930s in the area of the former Galicia (78,500 km²), now in Ukraine and Poland. The data was obtained as a result of manual vectorisation from 162 map sheets at scales of 1:115,200 and 1:100,000, according to the map legends. We...

Scots pine wood (Pinus sylvestris L.) is the most common wood material used in historical buildings in many parts of Central and Eastern Europe. Experiments were conducted natural aged wood (263 - 459 years old), extracted from construction elements of four historical buildings (from seven...

The paper attempts to compare the classification of sawn timber based on the norms used in Poland (PN-75/D-96000) and those valid in the European Union (PN-EN 1611-1). For the research, long pine logs were taken from five research areas in Poland. The obtained sawn materials were divided according...

Forest biomass is and will remain a primary source of renewable energy in many EU countries in the coming years. The aim of this study was to determine the energy potential of forest biomass on a regional scale with regard to the needs of its inhabitants in terms of electricity and heat...
