Economic Implication

The urgency to reduce resource depletion and waste production is expected to lead to an economy based on renewable resources. Biofuels, for instance, are a great green alternative to fossil fuel, but they are currently derived from edible vegetable oils such as soybean, palm, and sunflower. Concerns have been raised about the social–economic implication and ecological impacts of biodiesel production. Cultivating new lands as biodiesel feedstock rather than food supply, with the consequent increase in food prices, leads to so-called indirect land-use change (ILUC). Establishing bioenergy crops with phytoremediation ability on contaminated soils offers multiple benefits such as improving soil properties and ecosystem services, decreasing soil erosion, and diminishing the dispersion of potentially toxic elements (PTEs) into the environment. Castor bean is an unpalatable, high-biomass plant, and it has been widely demonstrated to possess phytoremediation capability for several PTEs. Castor bean can grow on marginal lands not suitable for food crops, has multiple uses as a raw material, and is already used in biodiesel production. These characteristics make it perfect for sustainable biodiesel production. Linking biofuel production with environmental remediation can be considered a win–win strategy.

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.

Mineral Oils

The transesterification of vegetable oil using various kinds of alcohols is a simple and efficient renewable fuel synthesis technique. Products obtained by modifying natural triglycerides in transesterification reaction substitute fossil fuels and mineral oils. Currently the most significant is the biodiesel, a mixture of fatty acid methyl esters, which is obtained in a reaction with methanol, which in turn is obtained from fossil raw materials. In biodiesel production it would be more appropriate to use alcohols which can be obtained from renewable local raw materials. Ethanol rouses interest as a possible reagent, however, its production locally is based on the use of grain and therefore competes with food production so it would implicitly cause increase in food prices. Another raw material option is alcohols that can be obtained from furfurole. Furfurole is obtained in dehydration process from pentose sugars which can be extracted from crop straw, husk and other residues of agricultural production. From furfurole the tetrahydrofurfuryl alcohol (THFA), a raw material for biodiesel, can be produced. By transesterifying rapeseed oil with THFA it would be possible to obtain completely renewable biodiesel with properties very close to diesel [2-4]. With the purpose of developing the synthesis of such fuel, in this work a three-stage synthesis of rapeseed oil tetrahydrofurfurylesters (ROTHFE) in sulphuric acid presence has been performed, achieving product with purity over 98%. The most important qualitative factors of ROTHFE have been determined - cold filter plugging point, cetane number, water content, Iodine value, phosphorus content, density, viscosity and oxidative stability.

Biofuel is one of alternative fossil fuel, in which the raw materials come from biological resources.One of the raw materials for biofuel production is microalgae. Microalgae grows rapidly, does notcompete with food for humans, and needs small areas to cultivate. Utilization of microalgae forbiofuel research nowadays is focusing on biodiesel production, but actually microalgae can beused to produce other biofuels such as bioethanol. The carbohydrate content of the microalgaecan be converted into glucose and fermented into alcohol. Carbohydrate content of the microalgaeis about 5.0–67.9%, which could produce bioethanol up to 38%. A harmony between bioethanoland biodiesel production from microalgae is needed for the optimum utilization of microalgae.Bioethanol production from microalgae can be done using de-oiled microalgae.

With the global biodiesel production growing as never seen before, encouraged by government policies, fiscal incentives, and emissions laws to control air pollution, there has been the collateral effect of generating massive amounts of crude glycerol, a by-product from the biodiesel industry. The positive effect of minimizing CO2 emissions using biofuels is jeopardized by the fact that the waste generated by this industry represents an enormous environmental disadvantage. The strategy of viewing “waste as a resource” led the scientific community to propose numerous processes that use glycerol as raw material. Solketal, the product of the reaction of glycerol and acetone, stands out as a promising fuel additive capable of enhancing fuel octane number and oxidation stability, diminishing particle emissions and gum formation, and enhancing properties at low temperatures. The production of this chemical can rely on several of the Green Chemistry principles, besides fitting the Circular Economy Model, once it can be reinserted in the biofuel production chain. This paper reviews the recent advances in solketal production, focusing on continuous production processes and on Process Intensification strategies. The performance of different catalysts under various operational conditions is summarized and the proposed industrial solketal production processes are compared.

Purpose. Creating Ukraine’s own feedstock base for the development of the biofuel industry through the use of energy-efficient technologies for growing high-yielding bioenergy crops on special energy plantations, which, along with high biomass growth for biofuel production, actively absorb carbon dioxide and emit significant amounts of oxygen. Research methods. Field, accounting, statistical, analytical. Results. Energy plantations of wood crops, which in a short term gives an opportunity to obtain a variety of high quality wood products. This line of business is new, which has already proven itself in world practice as one of the most profitable and reliable ways of investment. This process occurs most intensively in highly productive bioenergy crops of group C4, such as: paulownia, sugar sorghum, corn and sugar beets. As a rule, the invested funds are repaid for 3−5 years from the beginning of planting the energy plantation. For plantations with a short growing season, mostly fast-growing trees are used, which allows to reduce the growing season of trees from 10−20 to 3−5 years. This type of wood from specially created energy plantations can be used as a business and to process part of the raw material from waste, which is about 50% in the form of twigs, for fuel chips. Conclusions. The expediency of growing highly productive bioenergy crop of paulownia in different soil and climatic zones of the country in order to produce feedstock for the construction industry and biofuel production is substantiated. Ukraine has all the necessary prerequisites for this.

Indonesia biodiesel blending mandate emerged in 2006 driven by strengthening energy security while in parallel reducing and toning down the need for fossil fuels, strengthen the country's balance of payments and increasing environmental demand to reduce CO2 emission while leveraging the abundance of Crude Palm Oil as raw material. The purposes of this study were to analyze production and consumption of palm Oil-based biofuel. System dynamics model was developed based on 4 stages, Palm Oil Plantation, CPO Production, Palm Oil-based biofuel production and consumption and the validation of the model through Mean Absolute Percentage Error (MAPE) test confirms the correspondence between structures and phenomena. Baseline simulation analysis shows that there is no single strategy capable of improving the production and consumption of palm-based Palm Oil-based biofuel. We suggest that combined strategies such as government support hand in hand with industrial conversion efficiency, increase in palm oil on-farm productivity, 5% reduction in CPO export, Increase biodiesel production capacity and generally biodiesel utilization target cannot be achieved without the support from the government in form of subsidy which require additional IDR 409 a 15% increase in subsidy.

Abstract Background Cumulative reported evidence has indicated that renewable feedstocks are a promising alternative source to fossil platforms for the production of fuels and chemicals. In that regard, the development of new, highly active, selective, and easy to recover and reuse catalysts for biomass conversions is urgently needed. The combination of enzymatic and inorganic heterogeneous catalysis generates an unprecedented platform that combines the advantages of both, the catalytic efficiency and selectivity of enzymes with the ordered structure, high porosity, mechanical, thermal and chemical resistance of mesoporous materials to obtain enzymatic heterogeneous catalysts. Enzymatic mineralization with an organic silicon precursor (biosilicification) is a promising and emerging approach for the generation of solid hybrid biocatalysts with exceptional stability under severe use conditions. Herein, we assessed the putative advantages of the biosilicification technology for developing an improved efficient and stable biocatalyst for sustainable biofuel production. Results A series of solid enzymatic catalysts denominated LOBE (low ordered biosilicified enzyme) were synthesized from Pseudomonas fluorescens lipase and tetraethyl orthosilicate. The microscopic structure and physicochemical properties characterization revealed that the enzyme formed aggregates that were contained in the heart of silicon-covered micelles, providing active sites with the ability to process different raw materials (commercial sunflower and soybean oils, Jatropha excisa oil, waste frying oil, acid oil from soybean soapstock, and pork fat) to produce first- and second-generation biodiesel. Ester content ranged from 81 to 93% wt depending on the raw material used for biodiesel synthesis. Conclusions A heterogeneous enzymatic biocatalyst, LOBE4, for efficient biodiesel production was successfully developed in a single-step synthesis reaction using biosilicification technology. LOBE4 showed to be highly efficient in converting refined, non-edible and residual oils (with high water and free fatty acid contents) and ethanol into biodiesel. Thus, LOBE4 emerges as a promising tool to produce second-generation biofuels, with significant implications for establishing a circular economy and reducing the carbon footprint.

The article substantiates that the agricultural sector of Ukraine has a significant bioenergy potential. The first component of this potential is agricultural crops: traditional (cereals, sugar beets, sunflowers, rapeseed, etc.), which can be used for the production of bioethanol, biodiesel and energy crops (willow, poplar, miscanthus), which are used for the production of solid biofuels or second generation biofuels. The second component is organic waste from crops and livestock, which is a potential raw material for the production of biogas and solid biofuels. An algorithm for the development and implementation of a strategy for the development of biofuel production from the bioenergy potential of agrobiomass of agrarian enterprises has been offered with an emphasis on the obligation of its constant monitoring and correction to achieve the planned indicators. The expediency of using the SWOT-analysis methodology in the development of this strategy has been substantiated. The strengths and weaknesses of agricultural enterprises have been analyzed from the point of view of bioenergy development. For this, there were assessed their profitability and efficiency, the dynamics of growing of agricultural crops that can be used for the production of biofuel, and the volume of organic waste generated. Among the main strengths are strong bioenergy potential, weaknesses are resistance to change and the reluctance of managers to take risks by investing a lot in biofuel production. Analysis of the external environment showed the presence of both favorable (cooperation with international financial organizations, an increase in demand for bioenergy raw materials) and unfavorable factors for the development of bioenergy potential (high cost of equipment for bio-production, unfavorable credit policy, etc.). The combination of the strengths and weaknesses of the internal environment, as well as the opportunities and threats of the external environment of agricultural enterprises in bioenergy made it possible to identify four potential strategic directions for the development of using bioenergy potential of agrobiomass: organization of the production of all types of biofuels (liquid, solid, gaseous) by enterprises, energy autonomy; increasing of bioenergy potential in an intensive way, organizing the production of those types of biofuels for which bioenergy potential is the largest; building up bioenergy potential in an extensive way, selling bioenergy crops to Ukrainian biofuel producers; enterprises do not increase their bioenergy potential, they remain producers of only those agricultural crops for which there is a demand in Ukrainian and the world markets.
