“…Volume 1 Gcal of biomass will cost an average of about 1138.85 UAH. Substitute this value in the formula (2) to calculate the projected profit from the implementation of the planned volume of bioenergy production at the boiler capacity of 500 kilowatts on biomass from wood, wood pellets and straw pellets, respectively, and get 1 311 955 UAH for each type of biomass.…”

Topicality. Globalization is characterized by exponential rates of production of goods and services, extraction of natural resources, increase in energy consumption. This has led to climate change. As a result, it is necessary to find a solution to this problem in order to reduce the negative impact of humanity on the environment. One such solution is the production of bioenergy. Ukraine is still an agro-industrial country, and it has a high bioenergy potential. In recent years (2013-2018) bioenergy of Ukraine has started to develop, but the existing pace of development is not enough to achieve the goals set out in the main plan of the article. Potential bioenergy producers claim that there is no economic benefit from such activities. Therefore, this statement is analyzed and refuted. The paper evaluates the bioenergy potential of Ukraine, proves the economic effect of bioenergy production, forecasts the development of this sector, analyzes the impact of subsidizing natural gas consumers on the development of the bioenergy sector. The paper assessed the bioenergy potential of Ukraine in comparison with other countries, took into account the participation of Ukraine in international programs, forecast the development of the domestic bioenergy market. The study revealed that activities in the field of bioenergy has an economic and investment effect.

In view of the growing importance of distributed generation, the pluralization of the energy matrix close to large consumption centers has become necessary. In this sense, the energy sector can contribute to electricity generation using waste products such as vinasse, the most relevant in terms of volume and polluting capacity. The general objective of this article is to analyze the economic feasibility of using vinasse for electricity generation, and as a specific objective, to identify the viable price range of MWh in free and regulated energy environments and the productive capacity of plants for this type of investment. The methodology used was quantitative research, based on the cost structure of a biodigester IC internal combustion engine with 38% yield and vinasse logistics according to the production capacity of autonomous plants of 100 m3, 1,000 m3, and 3,000 m3ethanol/day for scenarios with and without tax exemptions for a price range between US$ 26.04 and US$ 130.20/MWh. The analysis shows that the use of vinasse for electricity generation is restricted to medium and large producers. Furthermore, the price of MWh is more relevant than the tax exemption for the feasibility of this type of project. This corroborates the constant requests from the sugar-energy sector to hold exclusive electricity auctions for biomass, given its cost structure and its social, economic, and environmental externalities.

Biogas production in the Sahelian zone faces the problem of water shortage during the dry season. This study was initiated in the bioscience laboratory at the University of Maroua with the objective of improving the accessibility of households to biogas in water scarcity conditions. Also another aim is to recycle the filtrate of the digestate into a new dilution of the substrate for biogas production. Thus, the Cow Dung (CD) digestate from the biogas unit was filtered. Two types of filters were made: filter with sand and cotton and filter with sand, biochar and cotton. The filtrate obtained was used to make five treatments with CD to feed mini biodigesters (1st generation) of 1 liter each. After a HRT of 30 days, the digestate from the 1st generation was again filtered into the same treatments (2nd generation). During the anaerobic digestion; the production and pH of each treatment repeated three times were evaluated. The effect of water recycling and the type of filtration were analyzed. This study shows that the dilution of CD with the filtrate from the 1st generation significantly improves on the production of biogas by 47% compared to that of dung diluted with ordinary water. In the 2nd generation, dilution with ordinary water provided the best production which is 7% higher than that obtained from the filtrates without biochar. As the pH is concerned, it varies between 6 and 7.5 when filtrates are used. It was more acidic when water has been used.
