“…During the research it was revealed that the destruction of polymer composite materials in the compost occurs in a two-step process. In the initial phases of degradation the chains of high molecular weight of polymer composite materials are hydrolyzed to oligomers with a lower molecular weight [11,12]. This reaction can be accelerated by acids, and also depends on temperature and humidity.…”

“…First, thermal modification allows removing from wood hemicellulose and lignin, which can adversely affect the contents of packages, reducing the shelf life of products. Secondly, thermal modification gives wood such properties as: high hardness, water resistance, chemical and biological stability [9,10]. Thirdly, thermally modified wood is environmentally friendly, that is important for food packaging materials.…”

To date, excessive use of non-degradable petrochemical-based polymers has resulted in a serious threat to the environment. In this regard, in recent years, green polymers are receiving more and more attention, because they are biocompatible, biodegradable and resistant in nature. Among these biopolymers, polylactide is considered the most promising alternative to traditional polymers due to its good biodegradability, biocompatibility and thermal stability, acceptable mechanical properties and excellent processability. This article has developed a biodegradable composite material based on polylactide and wood filler, subject to thermal modification. It was established that the addition of the maximum amount of vegetable filler reduces the time of decomposition of the composite, as a result of which it can be used in the packaging, food industry, as well as in agriculture and in everyday life.

“…Thus, the results presented in Figure 3 show the loosening of composites due to the formation of voids, which subsequently reduce the tensile strength. This happens due to the cracks which can easily spread through areas containing interfiber voids [19,21]. Therefore, it can be concluded that the inclusion of wood filler in the composite of more than 50% by weight of the composite significantly reduces the tensile strength of the polymer matrix.…”

Today, the technology of extrusion 3D printing of plastic products is developing at the highest rate, due to its availability. Therefore, the creation of composite materials, based on thermoplastics, which contain various additives, aimed at improving the physico-mechanical and aesthetic characteristics is becoming more important. In this regard, the studies on the effectiveness of using a thermally modified wood filler in the filaments, used in extrusion 3D printing technologies, were conducted in this work. It was found that the presence of a thermally modified wood filler reduces shrinkage of the composite and allows obtaining products with the smallest surface roughness. However, with a high content of filler in the composite, a decrease in its strength properties is observed.

Today, the limitations of traditional energy sources based on oil, natural gas and coal are becoming obvious. Therefore, the search for new sources of energy is a pressing issue both for modern Russia and for the whole world. The alternative sources of energy, based on the use of bioenergy of biomass, begin to play a significant and growing role in the world energy industry. The article presents the curves of changes in the mass yield of products obtained during the pyrolysis of biomass, thermally pretreated in the temperature range of 180-270 °C without access of oxygen. It has been experimentally proved that pre-heat treatment reduced the total liquid yield in the pyrolysis process: with an increase in the processing temperature, the mass yield of the liquid decreased, but the mass yield of charcoal and gas changed slightly. At the same time, it was found that the temperature affected the yield of the elemental composition of biomass: as the temperature increased, the content of elemental carbon in the biomass increased, while the content of hydrogen and oxygen decreased. It is concluded that the preliminary heat treatment of biomass can improve the quality of the final liquid biofuel by reducing the water content in it and by increasing the heat of combustion. It is also found that pressure reduction during the pyrolysis process increased the yield of the liquid fraction of decomposition products.
