Sufficient supply of woodworking with raw materials while preserving the ecology and rational use of wood is a necessary condition for the functioning of the woodworking industry as one of the key segments of the national economy. The issue is of particular importance given the deepening of world integration processes and the introduction of a moratorium on timber exports from Ukraine. It actualizes the study of the state and dynamics of the formation of raw materials potential of domestic woodworks. The purpose of the article is a structural and dynamic assessment of the economic and environmental aspects of formation of the resource potential of Ukrainian woodworks in comparison with the countries of the European Union, as well as in the regional section by types of wood. In the structure of merchantable wood harvested in Ukraine, fuel wood share increased by 4.3 pp. during 2011-2016, whereas in 2017 it increased by 3.8 pp. compared to 2016 and amounted to 61.4%. Unlike in Ukraine, in the vast majority of EU countries business timber is the basis of the structure of harvested merchantable timber. Thus, in the neighboring countries with similar forest landscape – Poland and the Czech Republic – the share of fuel wood in 2017 was 11.6% and 12.3%, in Slovakia – only 6.3%, and in the EU as a whole – 23. 2%. Hence, the significant deterioration of the structure of the harvested merchantable timber in Ukraine can be interpreted as a threat to environmental, and therefore to national security. On the other hand, the results of the assessments revealed an increase in the volume of commercial timber harvesting in Ukraine (in 18 regions) in 2018, as well as in the level of forest reproduction in the leading regions from the harvesting of merchantable timber (Zhytomyr, Kyiv and Rivne regions) and a decrease in the death rate. The restoration of the logical patterns between the dynamics of the loss of stands and the harvesting of commercial and fuel wood are signs of the beginning of positive tendencies in ensuring the preservation and rationalization of raw potential of domestic woodworks and, at the same time, improving the conditions for deepening the level of wood processing. Further authors’ research in this area will be devoted to the search for effective forms of wood industry development in Ukraine, in particular in the Western region.

The principles of selection and creation of rational methods of disposal and recycling of wastes are based on the fact that the problem of waste is an interconnected environmental-economic and technological problem, and the waste itself should be considered as technogenic raw materials of complex organo-mineral composition. Therefore, the main purpose of the work is to define methods for recycling waste and their environmental aspects. To achieve this goal, the methods of analysis, spectroscopy were used. It is determined that the final treatment of waste, to date, means either their disposal in a landfill or incineration, which adversely affects the environment. Methods for identifying the material of the object, as well as algorithms for the selection and recognition of objects by processing data from the computer vision system are considered. High accuracy is shown in 94.12% identification of plastic polymers.

Enhancing the role of scientific providing of radiation monitoring in agrosphere in the remote period of the radiation situation development after nuclear and radiation accidents has been justified. Recent problems and challenges of scientific support of agricultural production in the zone of Chernobyl NPP accidental emissions radioactive contamination in a remote period after the accident have been formulated. Radiation and environmental aspects of agricultural raw materials production in the regions contaminated by the Chernobyl disaster have been reviewed. It has been substantiated that further improvement of the radiological situation is possible with implementation of countermeasures aimed at the production of radioactively safe agricultural products and a thorough radiological control at its all levels.

In this paper it is identified and described the environmental aspects and impacts in a treatment plant wastewater. The inputs of raw materials, fuel, electricity and water are taken into account; similarly, the outputs as emissions, noise, discharges and waste, looking comply with environmental legislation and resource management. The most relevant results of the work leading to the qualification of environmental impacts studied for low and middle levels of significance area. The treatment plant wastewater meets its environmental management system, with appropriate controls on environmental impacts both normal and abnormal conditions. Higher level of significance was found in the areas of water pretreatment, but this has an environmental regulation and compliance under national law.

Abstract Future technologies should aim at reducing the consumption of raw materials and energy, avoid technical losses, to save energy and mineral resources, to minimize the emissions and waste, eliminate any irrational use of all resources and also to minimize the environmental impact. The paper present from environmental point of view both a classic forming process such as deep-drawing and incremental forming process. The paper gives an overview of the main environmental aspects regarding the incremental forming process.

This paper concerns problems related to the mechanical processing of mineral raw materials. The aspects explored were limited to the analysis of comminution technologies in terms of their effectiveness and energy consumption, modeling and simulation approaches, the assessment of crushing results, and environmental aspects. This article includes investigation of new technologies of comminution, comparing HPGR, high-voltage pulses, and electromagnetic mills. In the area of modeling and optimization, special attention was paid to the approximation of the particle size distribution of crushing products by means of Weibull, log-normal, and logistic functions. Crushing products with an increased content of fines were well characterized by Weibull’s distribution, while log-normal function adequately described HPGR products with a relatively low content of fines.

As a tropical country, Indonesia has enormous potential for the development of an industry with raw materials from coconut. One of the products that can be developed from coconut is coconut oil. The purpose of this research is to create a strategy and green business model in the medium coconut oil industry (klentik) by utilizing the waste it produces into a variety of prospective products with added value. Various prospective and value added products can be developed from coir, shell, coconut water, dregs, and blondo which are byproducts or waste from the coconut oil production process. The implementation of green business strategies and models has an impact on the sustainability of the medium-sized coconut oil industry, both in terms of profitability, social and environmental aspects.

The study investigated problems of determining the lot size by considering sustainability and capital constraints for purchasing raw materials and taxes. By using the Sustainable EOQ (SEOQ) models that considered environmental aspects, the researchers also evaluated the capital constraints. The proposed models were used to minimize total inventory costs. In this study, there was a practical numerical analysis and sensitivity analysis to help decision-makers and policies on inventory problems. Finally, the experimental results showed that the proposed models were effectively used to solve the problems.
