The current state of processing secondary raw materials of winemaking in Ukraine has been analysed. It has been shown that these materials are a rich source of bioactive compounds. This allows using them to manufacture a wide range of products (oenological tannin, food oenocolourant, polyphenolic extracts, tartaric acid, beverages, grape oil, vitamin D, protein, animal feed, food powder, fertilisers, abrasive materials, etc.) with high consumer value for various industries: food, pharmaceutical, perfume and cosmetics, chemical, compound feed, etc. In the light of modern views, phenolic compounds contained in large quantities in grape stems and pomace have been shown to be indispensable factors in nutrition and treatment. It has been noted that in today’s Ukraine, there are no specialised enterprises for complex processing of secondary raw materials of winemaking. In particular, unprocessed grape stalks and pomace are in most cases uncontrollably carried away to farmlands. This leads to acid erosion of the soil and to polluting the environment by micromycete metabolites, which but exacerbates one of mankind’s global problems, the environmental one. It has been concluded that traditional domestic technologies of processing secondary raw materials of winemaking are technologically, economically, and environmentally ineffective. There is no comparative analysis of innovative domestic and foreign technologies and equipment for processing secondary raw materials of winemaking. Modern innovations to obtain bioactive additives and other products cannot be introduced, since there is no necessary home-manufactured equipment, and imported machines are too expensive. Besides, there is but weak interaction among wineries, research institutions, business structures, and administrative authority. Cluster ideology has been suggested as a basis to organise comprehensive processing of secondary raw materials of winemaking in Ukraine. This will unite the interests of wineries (producers of secondary raw materials), processing enterprises (manufacturers of products from secondary raw materials), research institutions, and potential consumers of innovative products

The analysis of the current state of processing of secondary raw materials of wine-making in Ukraine is given. It is proved that the latter is a rich source of biologically active compounds, including phenolic ones, which makes it possible to use it for the production of a wide range of products (raccoon, polyphenol extracts, tartaric acid, beverages, fertilizers, grape oil, cake, vitamin D, animal feed, food powder, abrasives) with high consumer value for various industries: food, pharmaceutical, perfume and cosmetics, chemical, feed, etc. In the light of modern research, the role of phenolic compounds as essential nutrition factors that cannot remain out of the field of view of physiologists, pharmacologists, and food hygiene specialists is shown. However, currently in Ukraine there are no specialized enterprises for complex processing of secondary raw materials of winemaking; traditional technologies are not effective from a technological, economic and environmental point of view, which indicates not rational use of resources and loss of material resources; there are no systematic studies on physical and chemical, microbiological, Toxicological composition in order to determine the optimal direction of its use. A limiting factor is also the lack of comparative analysis of innovative domestic and foreign technologies for processing secondary raw materials of winemaking. In the vast majority of cases, in particular, combs and pomace are taken out of control to agricultural land without special treatment, which leads to acid soil erosion and pollution of the environment with metabolites of micromycetes, increasing one of the global problems of mankind-environmental. At the present stage of technological development, there are a number of innovative developments in the field of processing secondary raw materials, in particular grape pomace, in order to obtain biologically active additives, the limiting factor for the introduction of which is the lack of domestic and expensive imported equipment. A promising way to solve the existing problems is to create a mechanism that will unite the interests of wineries (producers of secondary raw materials of winemaking), processing enterprises (producers of products from secondary raw materials of winemaking), scientists and potential consumers of innovative products. Consolidation of the above-mentioned institutions and enterprises is possible by creating clusters for the development and implementation of innovative technologies and equipment

The article examines the current state and dynamics of development of the crop sector of the agricultural sector of Ukraine as one of the leading in the market management system. The products of the industry are extremely important for the national economy, because they are used as raw materials for the light and food industries, consumed in kind, used for animal feed. The production of plant products is associated with the cultivation of plants and the use of a specific and unique resource - land. However, the concentration of agricultural producers on the production of certain crops with high commercial attractiveness and their subsequent export led to a violation of the requirements of rational land use, which led to problems of socio-economic and environmental nature. Against this background, the most acute issue is the further development of the crop sector in terms of balanced use of agricultural land. The article analyzes the current state of development of the crop industry, namely: the dynamics of sown areas of crops and their structure; the analysis of volumes of production of agricultural products in natural indicators in dynamics is carried out; indicators of economic efficiency of agricultural land use are investigated; the state of mineral and organic fertilizers application to agricultural enterprises is determined; a SWOT-analysis of the development of the crop sector of the agricultural sector of Ukraine was conducted. It is established that this state of affairs requires the direction of the vector of agricultural policy in the direction of balancing the economic and environmental component of the use of agricultural land in order to ensure the preservation and reproduction of their fertility. Perspective directions of ensuring the development of the crop industry in the conditions of balanced use of agricultural lands are offered.

The object of research is the process of forming a collective expert assessment with increased reliability in making management decisions in business structures by an expanded team of experts. One of the most problematic places in the expert assessment of management decisions is the complexity of forming a competent expert team and the rather high cost of the expertise. In recent years, there has been a tendency for expert assessment with an expanded team of experts. In this case, not only professional experts are involved in the examination, but also all persons wishing to take part in solving the problem. In this case, the reliability of the examination raises doubts. In connection with the participation in expert assessment of persons who do not have experience in expert work, a wide range of expert assessments is possible. The analysis of the current state of the methods of expert assessment in business is carried out. It has been established that the Delphi method, which was most used until recently, does not meet modern requirements. More progressive methods are based on mathematical consensus theory. Consensus is understood as the degree of correlation of individual expert assessments performed in rank scales. In the course of the study, formalized mathematical approaches to the organization of collective expertise were used. A method for processing the results of an examination with an expanded composition of experts was developed. The developed methodology is focused on identifying experts with insufficient qualifications. The methodology allows for a step-by-step assessment of the reliability of the collective expert decision by assessing the Kendall concordance coefficient. It is shown that the phased exclusion of assessments by experts with insufficient qualifications allows increasing the level of consensus, the quality and reliability of the collective expert assessment. The developed methodology has been tested in a really functioning enterprise to make a decision on the exit strategy of the enterprise from their crisis. The use of the developed methodology has made it possible to significantly increase the reliability of the examination results, assessed by the concordance coefficient. The results are useful for practical application in business structures when conducting expert examinations involving a wide range of participants.

Human life and activities generate municipal solid waste (MSW) consisting of municipal household waste (residential waste), waste from commercial organizations, waste from public institutions and organizations, waste from industrial enterprises, waste from urban maintenance and improvement. A common feature for all these types of waste is the fact that a municipality is an institution responsible for organization, management of its disposal process. Such waste is generated in everyday life, across the food network, when carrying out repair and construction works, in the municipal transport and communication systems, etc. The aim of the work is to assess the current state and possibilities of oversized municipal waste management in the regions of Ukraine. In order to achieve this aim, the study of the existing regulatory documents and existing experience in the field of oversized municipal waste management was conducted. The work is based on the analysis of the published data, as well as on the materials of our own research. The implementation of the MSW management system implies creation of a municipal center for recycling secondary raw materials based on the modular quarterly principle. A recycling station with a mandatory module for oversized waste reception and sorting should become a main structural element of the recycling center. In addition, it is proposed to create separate sites for collecting the oversized waste. This has already been implemented in some cities of Ukraine. When differentiating SMW flows, due attention is not paid to the used cars that can contingently be attributed to oversized secondary raw materials. In Ukraine the existing recycling centers do not meet modern requirements. Due to the lack of necessary experience in handling the used cars, one should turn to foreign experience and focus on the requirements of the developed countries. According to international standards, the life of a car is 10 years with its subsequent utilization in such a way that prevents it from having a negative impact on the environment. Since, as of today, 27% of cars in Ukraine are older than 30 years, so in case of their mandatory utilization, the number of such cars will be approximately 2.5 million. With such total number of used cars each region of Ukraine will need to handle about 100 thousand recyclable cars. It is hardly possible to create the recycling centers in each region, so, at the first stage, it is advisable to organize such centers, for example, in each economic region or cluster. The creation of the oversized municipal waste management system in the regions of Ukraine will make it possible to turn the waste into useful products, to reduce the level of a negative environmental impact and to obtain not only ecological, but also socio-economic effects.

Topicality. Secondary raw materials of winemaking are a rich source of biologically active compounds, which makes it possible to use it for the production of a wide range of products of high value for various industries: food, pharmaceutical, perfume and cosmetic, chemical, etc. However, currently in Ukraine and in Moldova there are no specialized enterprises for the integrated processing of secondary raw materials of winemaking. In the vast majority of cases, in particular, crests and squeezes are uncontrolledly exported to agricultural lands without special treatment, which leads to acid soil erosion and environmental pollution by metabolites of micromycetes. At the present stage of technological development there is a wide range of innovative developments in the field of recycling of secondary bio-materials, in particular grape excrements, in order to obtain biologically valuable components. The main task in this direction is to create an organizational and economic mechanism that will unite the interests of winemaking enterprises (owners of secondary raw materials), processing enterprises (producers of secondary products of winemaking), representatives of local authorities and potential consumers of innovative products. A cluster ideology may be an effective tool for consolidating the interests of stakeholders in this direction. Aim and tasks. Development of the concept, formation and functioning of the cross-border cluster on the processing of secondary raw materials of winemaking, the core of which is the innovation-investment center, which provides cooperation of science, business and administrative resources, allows to provide non-waste technologies and use innovative solutions. In the process of recycling of secondary raw materials of winemaking in Ukraine and Moldova (about 100 thousand tons) is the possibility of obtaining more than 50 secondary winemaking products, which are in high demand in various sectors of the economy. The main objectives of this study are: ensuring sustainable development and the principles of the "green economy" in the development of viticulture and winemaking in Ukraine and Moldova; creation of high value-added biologically valuable products; obtaining social and synergistic effect in the process of forming a cluster. Research results. A systematic approach to the complex processing of grapes on the basis of cluster ideology is proposed. The proposed architecture of the cluster as managerial innovation in the subregional, regional, national and transboundary context allows us to form the poles of economic growth by consolidating and converting different types of capital: human, social, productive, natural, financial and intellectual to obtain additional economic benefits. The developed concept shows that sustained efficiency is achieved, first and foremost, enterprises are able to combine efforts and capital. Conclusions. The analysis of technology of processing of grapes on wine materials in Ukraine and Moldova is carried out. The following is the list of the most promising products obtained from secondary raw materials of winemaking. The concept of creating a cross-border cluster for the processing of secondary raw materials of winemaking, which is based on the principles of the green economy.

AbstractThis article serves to introduce the May 2004 issue of MRS Bulletin on Construction Materials: From Innovation to Conservation. By volume, building materials are by far the most widely used type of materials. The most common construction materials—concrete and wood—are paradigms of complex and hierarchical materials, with a microstructure extending quasi-continuously down to the nanoscale. In the past, most improvements have been obtained by modifying the microstructure at the largest scales, for instance, by reducing the macroporosity. Recent advances in our understanding of the interactions and microstructure development show that the major levers for improvement from now on will rely on surface and colloid science and the science of complex materials, often at the nanoscale. This can lead to remarkable properties, such as self-compaction and ultrahigh strength, and even new functionality, such as self-cleaning through photocatalysis. Construction materials face a wide range of challenges today, many of which are linked to the need for more sustainable development: reducing the consumption of raw materials, reducing the energy used in processing, and increasing service life. In many parts of the world, there is also an increasing need to repair, rehabilitate, and conserve old buildings. The articles in this issue touch on these challenges as well as the advances being made in construction materials through materials research.

Dicalcium silicate (Ca2SiO4) is a major component of Portland cement. It has also been investigated as a potential transformation toughener alternative to zirconia. It has five polymorphs: α, α'H, α'L, β and γ. Of interest is the β-to-γ transformation on cooling at about 490°C. This transformation, accompanied by a 12% volume increase and a 4.6° unit cell shape change, is analogous to the tetragonal-to-monoclinic transformation in zirconia. Due to the processing methods used, previous studies into the particle size effect were limited by a wide range of particle size distribution. In an attempt to obtain a more uniform size, a fast quench rate involving a laser-melting/roller-quenching technique was investigated.The laser-melting/roller-quenching experiment used precompacted bars of stoichiometric γ-Ca2SiO4 powder, which were synthesized from AR grade CaCO3 and SiO2xH2O. The raw materials were mixed by conventional ceramic processing techniques, and sintered at 1450°C. The dusted γ-Ca2SiO4 powder was uniaxially pressed into 0.4 cm x 0.4 cm x 4 cm bars under 34 MPa and cold isostatically pressed under 172 MPa. The γ-Ca2SiO4 bars were melted by a 10 KW-CO2 laser.

The article raises the problem of ensuring metrological traceability of the measurement results of indicators of quality and nutritional value for food products and food raw materials: water (moisture), nitrogen (protein, crude protein), fat, ash and carbohydrates. The problem under consideration can be solved by applying reference materials of food composition, traceable to state primary measurement standards GET 173-2017 and GET 176-2019 and primary reference measurement procedures (PRMP), for attestation of measurement procedures and accuracy checking of measurement results. The article discusses the results of the PRMP development of mass fraction of fat, ash and carbohydrates in food products and food raw materials, as well as mass fraction of crude fat (oil content) in oil crops seeds and products based on them. The paper also presents metrological characteristics of reference materials of composition of dry dairy products, grain-milk dry porridges for nutrition of babies, grain dry porridges for nutrition of babies, egg powder, freeze-dried meat products, animal feed. The results of the work allow for building a chain of metrological traceability from GET 173-2017, GET 176-2019 and PRMP to routine measurement procedures, thereby ensuring the uniformity of measurements of nutritional value of food products.
