Abstract Background Burning fast-growing trees for energy production can be an effective alternative to coal combustion. Thus, lignocellulosic material, which can be used to obtain chemicals with a high added value, is highly abundant, easily renewed and usually inexpensive. In this work, hemicellulose extraction by acid hydrolysis of plant biomass from three different crops (Chamaecytisus proliferus, Leucaena diversifolia and Paulownia trihybrid) was modelled and the resulting solid residues were used for energy production. Results The influence of the nature of the lignocellulosic raw material and the operating conditions used to extract the hemicellulose fraction on the heat capacity and activation energy of the subsequent combustion process was examined. The heat power and the activation energy of the combustion process were found to depend markedly on the hemicellulose content of the raw material. Thus, a low content in hemicelluloses resulted in a lower increased energy yield after acid hydrolysis stage. The process was also influenced by the operating conditions of the acid hydrolysis treatment, which increased the gross calorific value (GCV) of the solid residue by 0.6–9.7% relative to the starting material. In addition, the activation energy of combustion of the acid hydrolysis residues from Chamaecytisus proliferus (Tagasaste) and Paulownia trihybrid (Paulownia) was considerably lower than that for the starting materials, the difference increasing with increasing degree of conversion as well as with increasing temperature and acid concentration in the acid hydrolysis. The activation energy of combustion of the solid residues from acid hydrolysis of tagasaste and paulownia decreased markedly with increasing degree of conversion, and also with increasing temperature and acid concentration in the acid hydrolysis treatment. No similar trend was observed in Leucaena diversifolia (Leucaena) owing to its low content in hemicelluloses. Conclusions Acid hydrolysis of tagasaste, leucaena and paulownia provided a valorizable liquor containing a large amount of hemicelluloses and a solid residue with an increased heat power amenable to efficient valorization by combustion. There are many potential applications of the hemicelluloses-rich and lignin-rich fraction, for example as multi-components of bio-based feedstocks for 3D printing, for energy and other value-added chemicals.

Prospects for the development of hydrolysis production are determined by the relevance of industrial use of plant biomass to replace the declining reserves of fossil organic raw materials and increasing demand for ethanol, especially for its use as automobile fuel, protein-containing feed additives that compensate for protein deficiency in feed production, and other products. Based on the review of the research results presented in the scientific literature, the analysis of modern methods of liquid-phase acid hydrolysis of cellulose and various types of plant raw materials, including those that differ from traditional ones, is performed. The main directions of increasing its efficiency through the use of new catalytic systems and process conditions are identified. It is shown that the most promising methods for obtaining monosaccharides in hydrolytic processing of cellulose and microcrystalline cellulose, pentosan-containing agricultural waste and wood, are methods for carrying out the process at elevated and supercritical temperatures (high-temperature hydrolysis), the use of new types of solid-acid catalysts and ionic liquids.

The introduction of fruit plants into a culture enriches the diversity of the species composition of the regional flora and at the same time creates an opportunity for expansion of the plant raw material base for the needs of the food industry, inclusion in a full-fledged functional nutrition of the population. Among the fruit plants of the Dniprovsk region, every year, more attention should be paid to introduced low-frequency non-traditional fruit species, in which the fruits, leaves, stems and other parts have high nutritional value and are the source of physiologically active compounds that have anti-cancer, antibacterial and anti-inflammatory properties, carry cardio protective, antihypertensive, anti-diabetic effects, stimulate the central nervous system, etc., and can contribute to the prevention and treatment of many diseases.   Antioxidants additives in the raw materials and finished products ensures their prevention damage, reduce losses, increase shelf life and production of high quality products which keep for a long time characteristics inherent fresh, complete products. Preservation, restoration and introduction to the culture of any species depends primarily on its ability to multiply seed and vegetative methods. A comparative analysis of the fruit and seed ability of Berberis L. representatives grown in the botanical garden of Oles Gonchar’  Dniprovsky National University was carried out. The use of integrated research methods made it possible to carry out an integrated assessment of the regenerative capacity of the investigated representatives of the Berberis L. and to establish their biological ability to seed propagation depending on the seed quality of the seeds. The seeds length varied from 4.5 mm (B. canadensis) to 5.2 mm (B. declinata, B. amurensis), width was from 1.8 mm (B. amurensis, B. vulgares) to 2.1 mm ( B. coreana). The weight of 1000 seeds, which, depending on their size and completeness, amounted to an average of 10.16 grams. Largest weight 1000 pcs. seed is marked in B. coreana. As a result of the total antioxidant ability of the fruits, the species examined can be arranged in the following order:  B. koreana > B. x declinata > B. vulgaris > B. amurensis > B. canadensis. When comparing total antioxidant capacity level of the plants, the highest indices were characteristic for B. koreana and B. x declinata fruits, which exceeded the values of other species in 1.7-1.9 times. The relatively low antioxidants concentration in B. amurensis fruits is offset by a greater weight of the fruits of this species.  In order to enrich the range of ornamental and fruit plants, it is expedient to introduce into production of new crops and to expand the species diversity of Berberis L. representatives. Barberry reproduction process depends on many factors related to the environment. All investigated representatives of the Berberis L. are promising for further use in the planting system and as fruit plants that can be included in the functional nutrition of the population and use in the food industry in the conditions of the Steppe Prydniprovya.

High strength lightweight glass-ceramics were fabricated with coal gangue and clay as main raw materials. The utilization ratio of coal gangue, the ratio of the coal gangue with clay, mineralization agents, forming process and sintering process on the properties of the fabricated glass-ceramics were optimized. The utilization ratio of coal gangue reached 75, and the ratio of coal gangue to clay was 3/1, as an optimal property was observed. The optimal sintering temperature was found to be 1370?C. At this optimal temperature, the sintered glass-ceramics showed the main phase of mullite and spindle and so showed high strength, low density, and low water absorbance. The appropriate amounts of codoping of the TiO2, ZnO, and MnO2/dolomite as mineralization agents obviously enhanced the properties of the glass-ceramics. Process optimizations further determined reasonable and optimal process parameters. The high strength lightweight glass-ceramics fabricated in this work may be very suitable for various applications including building materials, cooking ceramics, and proppant materials, et al.

The development of an algorithm to automate the process of measuring the magnetic properties of macroscopic objects in motion is an important problem in various industries, especially in ferrous metallurgy and at factories where ferrous scrap is a strategic raw material. The parameter that requires work control is the hidden mass fraction of a non-magnetic substance that is present in the ferromagnetic raw material. The solution to this problem has no prototypes. In our work, a simple measuring device and a mathematical algorithm for calculating the mass fraction of the non-magnetic fraction in a strongly magnetic matrix were developed. The device is an inductance coil, in which the angle of the electromagnet losses is related to the mass of the magnetic material moving the coil. The magnitude of the instantaneous values of the lost angle integral was compared with the result of weighing the object on scales. This allowed us to calculate the proportion of the magnetic and non-magnetic fractions. The use of this prototype is herein illustrated. The experimental results of the determination of the magnetic-fractional composition depending on the mass of scrap metal and its bulk and the magnetic characteristics are presented.

In order to explore the effect of removing siliceous components on acid resistance of fracturing proppants, acid resistance of fracturing proppants in a new silicon-free system was studied in this paper. The fracturing proppants were made by pressureless sintering using high-purity alumina and barium carbonate as the basic raw material. Acid resistance test was carried out in 12 wt% HCl + 3 wt% HF at 65 oC for 30 minutes according to The Petroleum and Gas Industrial Standards of China (SY/T5108-2006) and morphology, structure and chemical analysis of the samples were investigated using X-ray diffraction and scanning electron microscopy. Experiments show that fracturing proppants that contain barium aluminates have better acid resistance. The acid solubility of the samples is less than 3%, especially when the content of barium carbonate is about 10% (mass fraction, the same below), the acid solubility of the sample reaches 0.52% which is far beyond the demands (5%) of the Standards of SY/T5108-2006. Results prove that the removal of siliceous components of raw materials can prominently improve the acid resistance of fracturing proppants. It can provide a new referential thought for improving the acid resistance of fracturing proppants.

Waste from agricultural and industrial production is one of the factors of environmental pollution. Together with this, they are a valuable raw material and can be used, for example, for the manufacture of additional animal feed. The article provides information on the rational use of valuable agricultural and industrial waste as additives in the rations of feeding farm animals and poultry. The health of farm animals and poultry, their productivity depends on the quality and balance of feed. An unbalanced diet leads to metabolic disorders. The data on the chemical composition of molasses, cake and meal, which are used in animal husbandry and poultry farming, as an additional feed with a high protein content, are given. Molasses, which is a by-product of sugar beet production, contains easily digestible carbohydrates, and its use in animal husbandry as an additional feed solves the problem of sugar deficiency. The Testing Center (IC) of the Federal State Budgetary Scientific Institution "FSBSI «FCTRBS-RRVI" conducted research on sunflower cake, rapeseed and sunflower meal in terms of feed value (mass fraction of moisture, mass fraction of crude protein, mass fraction of crude fiber, mass fraction of crude fat). The results of the study of beet molasses samples are presented in terms of quality indicators: mass fraction of dry substances, mass fraction of sugar (by direct polarization), and mass fraction of reducing sugars. The studies carried out indicate that 95% of cake, meal and beet molasses obtained from agricultural and industrial waste, in terms of feed value, meet the requirements of the current regulatory documentation.

When processing cattle and poultry, a large quantity of secondary slaughter products in the form of bone raw materials are formed in enterprises of the meat and poultry processing industry. Nowadays, its use is not optimal and rational. One of the promising directions of using bone raw materials in enterprises is production of finely ground meat and bone paste. The aim of this research was to study the chemical and mineral compositions, as well as the content of toxic elements in meat and bone paste from poultry and cattle bones obtained after complex grinding on a grinder and ultra-fine grinder. Chicken bone products (chicken necks, drumsticks, wings, breasts) and cattle costal and vertebral bones with residues of muscle tissue were used for investigation. The comparative analysis of the nutritional value of the meat and bone paste showed the following results: protein mass fraction was 18.5% in the meat and bone paste obtained from poultry bones, and 12.1% in the meat and bone paste obtained from cattle bones. The mass fraction of fat was two times higher in the meat and bone paste from poultry bones. As for the mineral composition, it has been established that meat and bone paste is a rich source of calcium: the calcium content was 1,654.02 mg/100g in the poultry meat and bone paste, and 5,318.13 mg/100g in the cattle meat and bone paste. In regard to the toxic element content, the normed values of lead and arsenic, cadmium and mercury were not revealed in the poultry and cattle meat and bone paste. The obtained meat and bone paste can be used for food purposes as a food additive in meat product manufacture, which will allow rational and economic use of bone raw materials in cattle and poultry processing.
