State Of The Environment

Currently, an urgent issue is the preservation of the environment, the cyclical use of waste for the production of new products, the preservation and multiplication of the planet’s natural resources. After all, the quality of life of each person directly depends on the state of the environment and the factors that affect its preservation. These factors are an integral part of the development of a green economy. This article discusses the possibility of producing alternative energy sources, such as biofuels of three generations.The first generation is solid, liquid, and gaseous biofuels. Second-generation fuel is obtained from the biomass of plant and animal material residues, or grown crops. As an example, such a type of fuel as biogas, which consists of carbon dioxide and methane, and with its further processing, namely the separation of carbon dioxide, you can get biomethane. In the same way, such fuels as biodiesel and bioethanol can be obtained from the biological mass. And the most unusual raw material for the production of third-generation fuel is biofuel from algae. Unfortunately, the development of the green economy in Russia is taking slow steps, but at present this issue is being paid more attention. The development of technologies for obtaining alternative energy sources will allow us to produce not only new types of energy, but also to preserve the environment of our priceless planet, through the use of raw materials and waste that are not in demand in everyday human life.

The need to safeguard our planet by reducing carbon dioxide emissions has led to a significant development of research in the field of alternative energy sources. Hydrogen has proved to be the most promising molecule, as a fuel, due to its low environmental impact. Even if various methods already exist for producing hydrogen, most of them are not sustainable. Thus, research focuses on the biological sector, studying microalgae, and other microorganisms’ ability to produce this precious molecule in a natural way. In this review, we provide a description of the biochemical and molecular processes for the production of biohydrogen and give a general overview of one of the most interesting technologies in which hydrogen finds application for electricity production: fuel cells.

The increasing shortage of fossil hydrocarbon fuel dictates the need to search for and develop alternative energy sources, including plant biomass. This paper is devoted to the study of the Miscanthus plants biomass potential and the analysis of technologies of its processing into products targeted at bioenergy, chemistry, and microbiology. Miscanthus is a promising renewable raw material to replace wood raw materials for the production of chemical, fuel, energy, and microbiological industries. Miscanthus is characterised by highly productive (up to 40 tons per one hectare of dry matter) C4-photosynthesis. Dry Miscanthus contains 47.1–49.7% carbon, 5.38–5.92% hydrogen, and 41.4–44.6% oxygen. The mineral composition includes K, Cl, N and S, which influence the processes occurring during biomass combustion. The total amount of extractives per dry substance lies in the range of 0.3–2.2 % for different extraction reagents. Miscanthus has optimal properties as an energy source. Miscanthus × giganteus pellets showed the energy value of about 29 kJ/g. For the bioconversion of plants into bioethanol, it is advisable to carry out simultaneous saccharification and fermentation, thus reducing the duration of process steps and energy costs. Miscanthus cellulose is of high quality and can be used for the synthesis of new products. Further research will focus on the selection of rational parameters for processing miscanthus biomass into products with improved physical and chemical characteristics: bioethanol, pellets, industrial cellulose, bacterial cellulose, carbohydrate substrate.

Italy is a country where the energy supply depends largely on imported raw materials (such as oil and natural gas). The favorable geographic location could encourage the development of renewable energy sources; nevertheless, the growth of alternative energy sources is slow. What are the reasons? This question will be dealt in this chapter, considering three different aspects of the issue: the economic incentives for renewable energies, the problematic process of authorization of the facilities and the local communities’ opposition to new plants. Besides the analysis of these issues, the aim of this paper is to identify possible solutions, taking into account the relevant legislative and regulatory changes that, at national and Community level, have affected and are affecting the field of renewable energy.

The Future

Abstract Wider use of alternative energy sources is a real requirement of sustainable economy – not only from the point of view of limited natural resources –, and there is a question what is the knowledge, the attitude of young generation. As there is a strong connection between the use of renewable energy and sustainability, the issues must be examined together. On the other hand it can be observed that there is a tendency that people are becoming more open and inquiring towards renewable energy sources, and environment protection is considered as a very important task. The main goals of the research were to examine the knowledge of the young generation taking part in higher education on sustainability and alternative energy, and to find out their attitudes to the use of different alternative energy sources. Also, our hypotheses said that the level of knowledge of sustainability and their attitudes to the environment issues are connected. We compared the results of two surveys carried out in 2014 among the students of a Hungarian and a Slovak higher educational institute. According to the primary results it can be stated that the increasing environmental awareness of young generation is visible, although as for the concepts of sustainability and their knowledge on alternative energy sources, as well as their expectations for the future, there was no significant correlation between their opinions in the Hungarian sample. It was proved that they have open minds towards environmental consciousness, and follow the renewable energy sources with attention. A bit more than a half of the sample has real knowledge on sustainability – we mean the three-pillars model here –, more the mail interview has higher knowledge and for the future they thought the question as a very important one. Considerable majority of the respondents, compared to their capabilities, try to live environmentally-sound life, will do more than one thing to save their environment, although also some negative responses slightly appeared in the received results. Primary results of the Slovak sample are similar; respondents do similar measures for environment at their households as their Hungarian colleagues, but with different priority. Concerning the knowledge of concept of “green economy”, “blue economy” and the “non-growth”, it can be summarized that the awareness is evident but in many cases, there is just few information and weak knowledge connected with the terminology and practical consequences. We think it is an important task of education to increase the awareness of young people on sustainable energy use and to let them accustomed to the thought of green economy and non-growth theories, since the expansion of knowledge may help in the development of a more positive attitude, which will then, hopefully, encourage their actions in the future.

Currently, the issues of production and use of alternative energy sources are gaining more and more popularity. Such traditional energy sources as gas, oil, and coal are irreplaceable minerals, and therefore there is a need to search for alternative energy sources. One of which is biofuels. Wood waste from woodworking and sawmilling enterprises accumulates in huge quantities on production areas and is not used properly, but is mostly burned or disposed of in landfills. The removal of waste to landfills requires a lot of investment, since wood has a large volume mass. At the same time, in many European countries, such wood-based materials as fuel pellets, fuel briquettes, and euro-wood are known, and they are the substitutes for traditional types of energy. Compared to traditional energy sources, biofuels have a number of advantages. One of them is that when burning, the amount of carbon dioxide released into the atmosphere does not exceed the amount of emissions that would be formed by the natural

The article states that Ukraine is among countries with a high potential level of biomass, which serves as a raw material for the production of solid biofuels. As Ukraine’s economy is developing, there is an increased demand for energy resources. In response to energy dependence and steadily rising prices for fuels, there has also been a shift in the focus towards using alternative energy sources such as biofuels, particularly, wood pellets. The paper covers the factors leading to the growth of the pellet industry, namely: improving the ecological situation, reducing carbon emissions, increasing prices on extracted fuels, waste recycling optimization, etc. The peculiarities of wood pellet production are outlined and their impact on decision-making processes in enterprises, especially in logistics-related areas, is discussed. A particular attention is paid to technology aspects of producing wood pellets and technological organization of manufacturing processes. The article summarizes a list of required production equipment, which affects initial investment, projecting production cost and financial results of operations. Some peculiarities of woodworking enterprises which provide raw material for wood pellet plants are considered. The major challenges and prospects related to forming a long-term strategy for producing wood pellets are highlighted. Based on the results of the study, a principle for optimizing production costs, particularly raw materials costs, is suggested. The optimization model includes all production costs incurred when producing pellets. It is also found that the optimal distance from the furthest sources of raw material should be up to 50 km. The article concludes that addressing various aspects of producing and consuming biofuels in Ukraine is relevant and important. Further studies should be performed into defining criteria for management in such type of plants.

Problems of climate change, environmental pollution, the search for alternative energy sources – these issues, as well as many others that can be characterized as constituent elements of the concept of sustainable development, or the “green” economy, come to the fore, becoming the most relevant in all spheres of human life ... The article formulates the concepts of conscious consumption and conscious investment. The main promising investment trends are identified, preferences in investing generation Z and their impact on the world economy are formulated. As an example of the trend of conscious investment, as well as a promising source of financing for «green» projects, the dynamics of the issue of a specific type of securities – “green” bonds is analyzed. The article analyzes the features of the «green» issue, and also formulates the author’s view on the pricing of this financial instrument. Illustrated is the “green halo effect” inherent in the portfolio of “green” bonds, which characterizes these securities as the most liquid in comparison with classic bonds. The effectiveness of the experience of issues of Russian companies in this segment is analyzed. Based on the results of the study, it was concluded that conscious investment opens up new prospects for the Russian economy, since for many investors today, adherence to the concept of sustainable development is higher than political views, and the growing number of its followers neutralizes the increased risk level of individual investments.
