Micro Credit

This paper introduces the results of a project initiated by Cantho University (CTU) on the introduction of micro-credits for addressing the environmental pollution in Vietnam’s craft villages. At Tan Phu Dong, a traditional rice powder production village in Sa Dec, Dong Thap, all wastes from domestic and production activities and animal husbandry were freely disposed into open water sources. This practice led to a negative impact on the local environment. With the financial support provided by the Bread for the World (BfdW), a micro-credit program was initiated in which farmers could borrow money to construct a biogas plant to treat animal husbandry and domestic wastes. In addition, the staff transferred biogas plant construction technology to the local masons and organized training courses on biogas plant operation and maintenance and biogas usage for the farmers and the local officials. 61 farmers borrowed money from the program to construct their biogas plants, followed by more than 250 farmers that constructed their biogas plants by their own finance after realizing the positive benefits of biogas plants. As result, the environmental pollution issue was solved step-by-step, thereby helping enhance the living conditions of the local community.

Implementation of the circular economy is one of the priorities of the European Union, and energy efficiency is one of its pillars. This article discusses an effective use of agri-food industry waste for the purposes of waste-to-energy in biogas plants. Its basic objective is the comparative assessment of the eco-efficiency of biogas production depending on the type of feedstock used, its transport and possibility to use generated heat. The environmental impact of the analysed installations was assessed with the application of the Life Cycle Assessment (LCA) methodology. Cost calculation was performed using the Levelized Cost of Electricity (LCOE) method. The LCA analysis indicated that a biogas plant with a lower level of waste heat use where substrates were delivered by wheeled transport has a negative impact on the environment. The structure of distributed energy production cost indicates a substantial share of feedstock supply costs in the total value of the LCOE ratio. Thus, the factor affecting the achievement of high eco-efficiency is the location of a biogas plant in the vicinity of an agri-food processing plant, from which the basic feedstock for biogas production is supplied with the transmission pipeline, whereas heat is transferred for the needs of production processes in a processing plant or farm.

The topic of this paper is the analysis of anaerobic fermentation in an experimental biogas plant. Technological processes and operation parameters were monitored; these processes and parameters include, for example, the optimal structure of the input material and the consideration of the prolonging of the duration of the fermentation process. The goal of prolonging the fermentation process is to obtain higher biogas (and methane) production and to decrease the fermentation residue effluvial emissions. Emphasis is also laid on the mutual co-fermentation of substrates with regard to further use of the results in solving technological problems in other biogas plants. This technological process was first monitored in 2009; that is, before the planned intensification and modernization of the experimental biogas plant. Thus, the evaluation of the process could become part of the planned intensification and modernization of the chosen biogas plant (extended by the addition of the second stage of methanogenesis). The results obtained from the experimental biogas plant, which is one of the pioneering biogas plants in the Czech Republic, may serve, to other biogas operators, as a base for the preparation of suitable input, and for improving the efficiency of anaerobic fermentation within their biogas plants. The goal of the improvement of the fermentation process is to fulfill the ecological aspects; that is, to cut down CO2 emissions and to reduce the negative impact of the fermentation process on the environment (reduction of effluvium and noise originating in biogas plants).

Biogas plants may support the transformation towards renewable-based and integrated energy systems by providing dispatchable co-generation as well as opportunities for biogas upgrading or power-to-X conversion. In this paper, a simulation model that comprises the main dynamics of the internal processes of a biogas plant is developed. Based on first-order kinetics of the anaerobic digestion process, the biogas production of an input feeding schedule of raw material can be estimated. The output of the plant in terms of electrical and thermal energy is validated against empirical data from a 3-MW biogas plant on the Danish island of Bornholm. The results show that the model provides an accurate representation of the processes within a biogas plant. The paper further provides insights on the functioning of the biogas plant on Bornholm as well as discusses upgrading potentials of biogas to biomethane at the plant from an energy perspective.

Material processing by PT Tukad Mas Kota Bima which has a negative impact, namely the existence of pollution or environmental damage in the East Rasa Nae Subdistrict, Bima City, so that it can be held accountable under criminal law, civil law and administrative law. The purpose of this study was to determine the form of criminal liability for environmental damage due to material processing by PT Tukad Mas Kota Bima. The research method used is empirical legal research with data collection techniques through interviews and documentation. The findings of this study indicate that legal liability for environmental damage due to material processing by PT Tukad Mas Kota Bima can be seen in aspects of criminal law, civil law and administrative aspects. However, the Bima City Government through the Environmental Service has only given a written warning to PT Tukad Mas Kota Bima, which has been operating for decades. Whereas empirical facts have shown that there is quite severe damage, such as waste disposal that can have a health impact on the community and natural damage due to excavations carried out. Criminal liability should be a special concern, NGOs and the community even report on environmental crimes, the report is because the result of material processing causes environmental pollution as one of the elements of criminal acts against environmental pollution.

Negative impact on the environment as a result of economic activity of man increasingly becomes the character of combined pollution of ecotoxicants, including xenobiotics of radiation and chemical nature. In animal husbandry in ecologically unfavorable regions, sorbtion-detoxication technologies based on the complex application of bioprotective substances of different origin are used to reduce the intake and accumulation of xenobiotics, to normalize the physiological state of animals and to obtain safe products. It is necessary to observe certain principles ensuring compatibility of components, a wide range of bioprotective action, efficiency and safety at their use in developing the compositions of such sorption-detoxifying complexes. The article substantiates the criteria that should be followed in creating sorption-detoxifying complexes and presents groups of drugs with different mechanisms of action (sorbents, antioxidants, immunomodulators, adaptogens and other biologically active substances) for inclusion in the formulations of combined compositions.

The main trend in energy development is to increase energy efficiency by reducing the use of limited natural resources, the spread of renewable energy, and reducing the negative impact on the environment. An effective response to these challenges is the use of biogas plants that produce clean energy and solve the environmental problems of waste disposal and recycling. The purpose of the article is to assess the economic efficiency of replacing district gas supply with autonomous biogas plants in public utilities. A hypothesis has been put forward that the feasibility of using such technologies depends on climatic features and the specific provisions of state regulation of prices and gas consumption rates. A cost approach was applied that assesses the overall structure of equipment costs, as well as a comparative assessment method according to the principle “with / without a biogas plant”, and a scenario analysis, the criterion of which is the size of the family owning the plant. An auxiliary method for forecasting retail and economically justified prices for natural gas for the population was used. The object of calculations is the “HomeBiogas” installation intended for home use. Three Russian cities were chosen as territorial subjects: Yekaterinburg, Irkutsk and Krasnodar. The cities which differ significantly in their natural characteristics and approaches to the formation of retail gas prices. It has been proved that although the average monthly temperatures differ significantly in the cities considered, none of them has a constant temperature exceeding the required standard value of 17°C. In each case, the initial capital investment is driven up by the cost of installing additional insulation and heating systems. This equalizes the costs of warmer and colder areas. Therefore, the climatic features of cities are not significant and do not affect the economic efficiency of using a biogas plant. In turn, state regulation of prices and norms of gas consumption by the population is of decisive importance. The findings are of theoretical and practical importance. The methodology can be applied to assess the efficiency of using biogas plants in industry and gasification projects in the remote areas of Russia.

The Republic

Global climatic changes have a negative impact on the development of all sectors of the economy, including agriculture. However, the very production of agricultural products is one of the most important sources of greenhouse gases entering the atmosphere. Taking into account the need to reduce the “carbon footprint” in food production, a special place is occupied by the analysis of the volume of greenhouse gas emissions and the development of measures for their sequestration in agriculture. One of the main directions for reducing emissions and immobilizing greenhouse gases is the development of special techniques for their sequestration in the soil, including those used in agriculture. Adaptation of existing farming systems for this task will significantly reduce the “carbon footprint” from agricultural production, including animal husbandry. The development of carbon farming allows not only to reduce greenhouse gas emissions, but also to significantly increase the level of soil fertility, primarily by increasing the content of organic matter in them. As a result, it becomes possible, along with the production of crop production, to produce “carbon units” that are sold on local and international markets. The paper analyzes possible greenhouse gas emissions from agriculture and the potential for their sequestration in agricultural soils. The role of various elements of the farming system in solving the problem of reducing the “carbon footprint” is considered and ways of developing carbon farming in the Republic of Tatarstan are proposed
