A systematic approach based on environmental and technological criteria has been proposed to ensure the achievement of environmental quality standards of the environment at the regional intersectoral level for the management of industrial and municipal waste. A list of indicators and criteria has been formed for comparing the accumulating capacity of a given natural system without serious violations of its structural and functional characteristics on the one hand. On the other hand, there is production potential and production capacity for natural resources for individual enterprises and a diversified industrial complex. An algorithm for comparing production and natural potentials on the basis of a geographic information basis on the scale of a territorial natural production complex has been developed and the structure of a GIS project has been determined. The latter made it possible to interconnect the natural intensity of production (NP), the level of environmental friendliness of production (EFP), the ecological technological capacity of the territory (ETT) using the criteria of commensuration (NDV, VAT, PDRO and NDT).

Natural-industrial complexes development is dictated by need of production and natural potentials comparison due to changes in environmental legislation. Functional model of simulation modeling natural-industrial complex with base and bank of excess information in single structure of geo-information system is proposed. Modern concept of environmental regulation on sector wide level has been applied. Algorithm for simulation modeling based on geo-information simulating system to achieve target state and stability of all elements in natural-industrial complex with identified functional relations is developed. Integrated indicators of production environmental capacity and ecological technical intensity of territory are harmonized. Various scenarios of simulation modeling are considered in accordance with management structure of territorial natural production complex, provided that ecological and technological models are interconnected within single functional model. As criteria, regional and national norms and standards are applied. Each nature user receives, in accordance with modeling results, certain share of accumulating capacity and corresponding quota. Main stages of geo-information model creation for natural-industrial complex management are determined. Principal functional model on geo-informational basis and management structure of territorial-natural-industrial complex are built. Considered methodology allows to apply modern geo-information technologies both to create databases for all subjects of natural production complex under consideration, and to justify model and parameters of its management with definition of individual allowable load quotas.

Limited development opportunities for almost every company requires an appropriate methodology for assessing the use of production potential of the enterprise.The organization of the production capacity assessment procedure should be considered as a system. On the one hand, it must be comprehensive to ensure the completeness of the information field for all types of resources and the purpose of their use, on the other hand, in order to save costs, it is advisable to combine this system with the control system of the enterprise. When studying the problems of determining the effectiveness of resource potential, it is necessary to consider approaches to its evaluation. Comprehensive assessment of the production potential of the enterprise is a necessary stage of strategic and crisis analysis and management. A large number of approaches to assessing the production potential of the enterprise does not always correspond to economic conditions, not all should be used to assess the production potential of the port enterprise. Assessment of each component of production capacity allows not only to determine the overall level of capacity, but also to assess the efficiency of resource use depending on the value of individual indicators. Other approaches are more likely to determine the overall level of capacity, without focusing on assessing the completeness of its use. The clarification of criteria for assessing production potential is required. The change in indicators that can be useful for assessing the level of potential depends on the specialization. For example, for the port industry, indicators include the use of fixed assets. To establish specific assessment criteria, it is necessary to group port enterprises according to the overall level of capacity.Assessment of production potential of enterprise is an important stage of management, which is the basis for determining the level of capacity and optimization of management decisions on its development.Keywords: enterprise potential, production potential, evaluation methods, production capabilities, efficiency evaluation, enterprise management.

Изменение природоохранного законодательства предопределило необходимость развития и создания новой методологии экологотехнологического нормирования допустимого сброса по критериям уровня экологичности производства, как суммы производственных природоемкостей при необходимости их соизмерения с региональным природным потенциалом. Исследованы и предложены решения по отдельным определяющим факторам и количественным значениям сбалансированности природоёмкости для природнопроизводственного комплекса «прибрежная акватория Ладожского озера – совокупность производственно-хозяйственных объектов целлюлозного завода». В соответствии с экологической техноёмкостью обозначенной акватории Ладожского озера определены два этапа расчета норм допустимых сбросов (НДС): по предельно допустимым концентрациям (ПДК) для расчетных показателей целлюлозного завода после очистки на сбросе; с учетом конструкции и характеристик глубинного водовыпуска, а также эффекта струйного и основного разбавления до контрольного створа. Представлены структура и методология оценки фактического уровня экологичности целлюлозного природно-производственного комплекса на примере первого расчетного этапа достижения НДС по ПДК. Предложенные в работе мероприятия поэтапного повышения экологичности до 3,5 и соответствующего уровня по степени очистки сбрасываемых стоков с учетом эффектов струйного и основного разбавления обеспечивают достижение НДС. Выполнен комплекс исследований и статистического анализа, который позволил оценить фактический уровень экологичности основного и вспомогательного производств целлюлозного завода, а также по целевым показателям с учетом специфики щелокосодержащих стоков. Предложен для реализации ряд целевых технологических мероприятий, повышающих уровень экологичности целлюлозного завода и минимизирующих соответственно техногенную нагрузку в пределах экологической техноёмкости водной акватории по рыбохозяйственным стандартам специфических для целлюлозного завода показателям. Changing environmental legislation decreed for the authors, in this paper, the necessity of development and creation of new methodology of ecological-technological regulation of the permissible discharge criteria level of environmentally friendly production, as the sum of the production nature intensity their commensuration with the regional natural potential. The paper investigates and proposes solutions for certain determining factors and quantitative values of the balance of natural resource intensity for the natural production complex «coastal waters of lake Ladoga – a set of production and economic objects of a pulp mill». In accordance with the environmental technology intensity of the designated lake Ladoga water area, two stages of calculating the permissible discharge rates (PDR) were determined: according to the threshold limit value (TLV) for the calculated indicators of a pulp mill after treatment at the discharge; taking into account the design and characteristics of the deep water outlet, as well as the effect of jet and main dilution to the control gate. The structure and methodology of assessing the actual level of environmental friendliness of the cellulose natural production complex is presented on the example of the first calculated stage of achieving PDR under the TLV. The actual security proposed in the work activities gradual increase of ecological compatibility to 3.5 and the appropriate level according to the degree of purification of wastewater taking into account the effects of the jet and the primary dilution to achieve PDR. A set of studies and statistical analysis was performed, which allowed us to assess the actual level of environmental friendliness of the main and auxiliary production of the pulp mill, as well as target indicators, taking into account the specifics of alkali-containing effluents. Proposed to implement aер number of targeted technology events, enhance the level of environmental performance at the pulp mill and minimize, respectively, the anthropogenic load in the range of environmental technology intensity water areas for fisheries management standards specific to pulp mill performance.

The aim of the study was to examine the changes in production and export of raspberries and sour cherries, which are the domain of Polish production on the international markets, in the countries of Eastern and Southern Europe during the 2006-2017. There was used data from Faostat database for the analysis of fruit production, and from Comtrade database for the analysis of export volume. Study points to the development of production and an increase in the export of raspberries in countries with a smaller area of cultivation of this fruit crops and stability in countries with a large area of crops of raspberries. In the case of sour cherries, in most countries, both large and small area plantings, production potential, and volume of production of fruit of this species declined. The export of sour cherries increased particularly from countries with less potential in the production of sour cherries. The development of the production and export of raspberries from countries with lower production capacity may in the future be competition for Poland on the international markets.

Presently water pollution is the one of the major threats faced by living things all over the world. The main cause of water pollution is its effect on the life of aquatic animals. Organic, inorganic, microbial and other pollutants often mix with water bodies mainly due to human activities. Because of the presence of pollutants in water, the amount of dissolved oxygen level can be decreased which in turn affect the survival of aquatic life. The pollutant water may enter the agriculture fields and damage the plants extensively. The methods, such as, coagulation, adsorption, foam floating, electrodialysis, capacitive deionization, etc. are presently employed to treat the waste water. Among these methods, heterogeneous photocatalytic degradation is considered to be a good method because of its low cost and environmental friendliness. In this review, the decontamination of different kinds of organic, inorganic and microbial contaminants in water with different photocatalysts process is presented.

Transformational processes in modern supply chains are experiencing a significant impact of global environmental problems and are focused on increasing the level of efficiency of the supply chains’ operation and ensuring the competitiveness of goods passing through them towards the end consumer. On the one hand, the parameters of all parts of the logistics chains must be in line with the international environmental requirements; on the other hand, compliance with the principles of environmental friendliness serves as a prerequisite for meeting the needs of modern consumers with a high level of environmental awareness. Logistics operations are a source of negative impacts on the natural environment. First of all, this concerns greenhouse gas emissions during transportation, waste products and packaging materials, noise and dust pollution, landscape changes and the use of natural resources. Therefore, environmental challenges stipulate the cooperation of all participants in supply chains, aimed at creating and implementing the effective environmental strategies and logistics concepts. The need for ecologization of Ukraine’s transport and logistics system is dictated by the need to achieve a high level of its competitiveness as an element of the global supply chain network. And although the domestic logistics system by a number of indicators is characterized by a low level of environmental friendliness, there is a consoling positive tendency to realize the need for an environmental orientation of its development both among the state authorities, and the logistics operators themselves.

: The study evaluates production parameters (height, diameter at breast height, volume) of Douglas fir (<I>Pseudotsuga menziesii</I> [Mirb.] Franco) at mesotrophic sites of the Křtiny Training Forest Enterprise in mature stands. In total, 29 mixed stands were assessed with the registered proportion of Douglas fir at an age of 85 to 136 years. Comparing the 10 largest Douglas firs with the 10 largest spruces or larches higher, and as a rule markedly higher, production potential of introduced Douglas fir was found in all assessed stands. There were also groups of trees where the volume of Douglas fir was twice to 3 times higher than the volume of spruce or larch (see Tabs. 5 to 10). For example, in stand 177B11, the mean volume of 9.12 m<sup>3</sup> was recorded in the 10 largest Douglas fir trees but the volume of spruce reached only 3.17 m<sup>3</sup> and the volume of larch was 3.70 m<sup>3</sup>. Differences in mensurational parameters of Douglas fir found on the one hand and of Norway spruce (<I>Picea abies</I> [L.] Karst.) or European larch (<I>Larix decidua</I> Mill.) on the other hand compared by ANOVA tests were statistically highly significant. Annual ring analyses have shown that at present the volume increment of particular Douglas fir trees ranges from 0.12 to 0.16 m<sup>3</sup> per year in mature stands (i.e. about 1.5 m<sup>3</sup> every 10 years).

The Impact

Municipal waste treatment is inherently associated with odour emissions. The compounds characteristic of the processes used for this purpose, and at the same time causing a negative olfactory sensation, are organic and inorganic sulphur and nitrogen compounds. The tests were carried out at the waste management plant, which in the biological part, uses the methane fermentation process and is also equipped with an installation for the collection, treatment, and energetic use of biogas. The tests include measurements of the four odorant concentrations and emissions, i.e., volatile organic compounds (VOCs), ammonia (NH3), hydrogen sulphide (H2S), and methanethiol (CH3SH). Measurements were made using a MultiRae Pro portable gas detector sensor. The tests were carried out in ten series for twenty measurement points in each series. The results show a significant impact of technological processes on odorant emissions. The types of waste going to the plant are also important in shaping this emission. On the one hand, it relates to the waste collection system and, on the other hand, the season of year. In addition, it has been proved that the detector used during the research is a valuable tool enabling the control of technological processes in municipal waste processing plants.
