The aim of the work is to analyze technical and economic basis for the development of energy and biofuel production from sunflower growing by-products in Ukraine. The task of the work is to determine conditions that ensure the economic feasibility of such type projects in Ukraine. Results of assessment of the energy potential of sunflower production by-products in Ukraine are presented. Ukraine is a world leader in terms of sunflower gross harvest. Consequently the country has a large potential of by-products from sunflower growing and processing available for energy. Today, with the exception of sunflower husk, this type of biomass is practically not used for energy needs. Small amounts of sunflower growing by-products are mainly used by some agricultural producers and rural households to cover their own needs in heat. Taking into consideration the insufficiently described practice of harvesting this type of biomass and the undoubted prospects of its use for energy in Ukraine, it is necessary to conduct some field tests of harvesting technologies, at least on the basis of existing agricultural machinery, in particular, forage harvester and mulcher with a baler. Further research is needed on the technology of direct combustion of stalks and other by-products of sunflower growing, as well as the production of solid, liquid and gaseous biofuels from them.

Worldwide, the wastes derived from food production are generated in elevated volumes annually. In particular, the cocoa industrial wastes represent a source of usable biomass for the elaboration of new products such as food, livestock feed, cosmetics, and chemical products, and they can even be used for the generation of biofuels. The cocoa industrial wastes include cocoa pod husk, mucilage, and bean shells, which contain compounds of interest for different industries. However, the lignocellulose content of these by-products requires a pretreatment to fully utilize them; thus, different biofuels can be produced, depending on the conversion technology used to obtain the highest biomass yield. Recent studies reported the use of cocoa industrial wastes for the production of solid, liquid, and gaseous biofuels; nevertheless, the most common use reported is as a direct combustion source, which is used to supply the same production plants. Therefore, the objective of this work is to carry out a review on the uses of the by-products generated from cocoa for the generation of biofuels, as well as the technological concept applied for the transformation. In addition, the future trends indicate the relevance of using catalysts in production to increase reactions in the conversion of compounds, including the use of statistical models to optimize the processing variables.

The article is devoted to determining the energy and economic efficiency of biofuel production from by-products of crop production. The following methods were used in the research process: monographic (in studying the economic and energy efficiency of plant biomass production in agricultural enterprises); statistical and economic (estimation of potential efficiency of crop production by-products); comparative analysis (when analyzing the economic efficiency of biomass production depending on crops); energy analysis (energy assessment of crop by-products potential of fields). The yield of basic products was determined by recalculating the yield of each crop to standard humidity and purity. The output of the by-products was established using special methods – a generalized assessment of the technically achievable energy potential of biomass and the methods of calculating the available potential of agro-raw materials. According to the results of the study, the yield level of the main products was analyzed, the economic efficiency of the production of by-products was determined, taking into account the crop residues (straw, stems) of winter wheat, corn, soybeans and sunflowers in the conditions of agricultural enterprises of the Myrhorod district of Poltava region. The amount of energy gain to generate heat is calculated depending on the plant biomass when used as biofuel feedstock. The available crop by-product potential of the crop production was evaluated, followed by the determination of the energy and economic efficiency of biomass. The potential of non-market crop production of winter wheat, soybean, corn and sunflower as alternative fuel and a basis for increasing the profitability of agricultural production has been determined which in the aggregate effect – attests to their profitability. Keywords: main products; by-products; economic efficiency; energy potential.

In recent years, the circular economy and sustainability have gained attention in the food industry aimed at recycling food industrial waste and residues. For example, several plant-based materials are nowadays used in packaging and biofuel production. Among them, by-products and waste from coffee processing constitute a largely available, low cost, good quality resource. Coffee production includes many steps, in which by-products are generated including coffee pulp, coffee husks, silver skin and spent coffee. This review aims to analyze the reasons why coffee waste can be considered as a valuable source in recycling strategies for the sustainable production of bio-based chemicals, materials and fuels. It addresses the most recent advances in monomer, polymer and plastic filler productions and applications based on the development of viable biorefinery technologies. The exploration of strategies to unlock the potential of this biomass for fuel productions is also revised. Coffee by-products valorization is a clear example of waste biorefinery. Future applications in areas such as biomedicine, food packaging and material technology should be taken into consideration. However, further efforts in techno-economic analysis and the assessment of the feasibility of valorization processes on an industrial scale are needed.

Nowadays, most Italian biogas produces electricity even though recent political incentives are promoting biomethane from biogas by “upgrading” it. The aim of this paper is to focus on the regulatory framework for producing biomethane from new or already-existent anaerobic digestion plants. The complexity and lack of knowledge of the regulations on biofuel production and of anaerobic digested biomethane from waste and by-products create difficulties of both interpretation and application. Consequently, the aim of this paper is to analyze the regulations for producing biomethane, underline the critical issues and opportunities, and evaluate whether an electrical plant built in the last 10 years in Italy can really be converted to a biomethane plant, thereby lengthening its lifespan. Three case studies were considered to look more closely into applying Italian biomethane incentives and to simulate the types of incentivization in agriculture with examples based on certain fuel types typical of a standard biomethane plant of 500 standard cubic meter per hour. All the considered cases put in evidence that biomethane is a further opportunity for development with a high level of efficiency for all biogas producers, especially for many biogas plants whose incentivization period is about to finish.

In this article analyzes the development of trends of bioenergy crops market development in Ukraine and its current state are analysed. The possibility and feasibility of synergy of mutual development of bioenergy crops market and bio-oil market in Ukraine were noted. The necessity of state support and stimulation of bioenergy crops and different types of biofuels production in Ukraine was stated. A positive trend of growth of planted areas and production of rapeseed in Ukraine was revealed. During the study period (2013-2019) the production of rapeseed was increased by 1.4 times. The greatest energy potential for the production of bioethanol is in the sugar beet subcomplex of the agricultural sector. Over the past few years, the production of sugar beet was at its highest in 2014 (15.7 million tonnes), while the following years saw a decrease in cultivated areas of sugar beet and, consequently, a drop in its gross output - to 8.3 million tonnes in 2020. Significant resource potential for the production of bioethanol also have cereal crops (wheat, rye, barley, maize), the area under which during the last ten years remains relatively stable (14.4-15.3 million ha). Among grain crops the most effective raw material for the production of bioethanol is maize. A positive tendency of biennial growth of planted area under this crop is revealed. The space differentiation of resource base of bioenergy in Ukraine is prominent. The cluster analysis revealed three groups of areas based on the similarity of the energy resources for bioenergy purposes. Two clusters including Khmelnytskyi, Ternopil, Zhytomyr and Chernihiv, Vinnytsia, Cherkasy, Sumy, Kirovograd, Poltava and Kyiv regions should be considered as the most promising areas for concentration of capacities in biofuel production. It is noted that the trajectory of development bioenergetic sector of the country is always conditioned by compromise between compliance with optimal levels of its energy and food security.

Nowadays the problem of industrial wastes handling and disposal is increasing continuously, as more strict environmental considerations have to be taken into account. In this paper, selected experimental results are presented from our current research in toxic metals removal (e.g. Cu, Pb, As), related to the applications of mineral particles as by-products (red mud, pyrite, dolomite, etc.) for the induced removal of toxic metals from aqueous solutions. These by-products, existing in finely divided form and considered rather as solid industrial wastes, have been used as a cheap solid adsorbent or substrate. Appropriate methods for the subsequent solid/liquid separation were examined, among them flotation. Different parameters were tested and high removals of toxic metals were achieved. In this way, a useful application may be realized for the waste mineral particles.

A brief technical and economic insight into producing the water-soluble yellow colorant limocitrol 3-O-6”-[3-hydroxyl-3-methylglutaryl)])-β-D-glucopyranoside from waste lemon peel via simple solid-liquid extraction in aqueous ethanol or via hydrodynamic cavitation of waste lemon peel in water, shows that the biocolorant can be obtained at affordable cost. Coupled to the simplicity and sustainability of the extraction processes suggested, the high chemical and physical stability of this polymethoxylated flavanol and the health benefits of citrus flavonoids, support industrialization of this new bioeconomy production.

In our paper we researched the state regulation in agriculture of Ukraine, as well as world experience in this field. The distribution of state financing for support of agricultural production is analyzed. We singled out the direction of state support to the agrarian sector of Ukraine. The directions of organizational reforming of households in the market conditions are investigated. The variants of integration of households of the population into more consolidated economic forms are offered. The priority of the development of cooperatives in agriculture has been argued. The positive experience of state support of servicing cooperation is considered on the example of «The Benefits of the Development of Personal Peasant, Farmers, Cooperative Movement in the Village and Advice Service for 2016-2020» of the Vinnytsia Region. The prospects of creation of cooperatives for the provision of oilseeds processing services for the energy needs of agribusinesses and provision of livestock feed with forages are argued. The prospects for realization of the program of development of agricultural servicing cooperatives within the boundaries of Ukraine are outlined.  Keywords: agrarian policy, agribusiness development program, agricultural servicing cooperative agriculture, cooperation, food safety, energy security, enterprise-agro producer, integration of farms, state support of agrarian sector
