Item Ecological aspects of alcohol industry enterprises modernization at present stage of development(Видавництво Львівської політехніки, 2020-02-24) Havryshko, Marianna; Popovych, Olena; Yaremko, Halyna; Lviv Polytechnic National UniversityAt the present stage of development, the entire world industry has faced the problem of rational use of renewable natural resources, in particular the most efficient ways of wastewater treatment and the use of accumulated waste in the production process as secondary raw material. In particular, the alcohol industry, as one of the components of food, medical, chemical and various industries, leads to the formation of a huge amount of waste, including wastewater. The food industry, like any other industry, has a negative impact on the environment. Water bodies are the most affected by the food industry. Almost the first place in terms of water consumption per unit of production is the production of alcohol. Consumption of large amounts of water leads to the formation of wastewater, which is highly polluted and adversely affects the environment. Due to the high chemical and biological consumption of oxygen, specific colour and odor, suspended solids, low pH value, the purification of such waste in the filtration fields, and discharge into water bodies is not possible. The purpose of our work is: 1) the analysis of the alcohol industry potential in Ukraine in recent years, and methods of waste disposal as a potential source for the development of bioenergy. 2) environmental aspects of the alcohol industry modernization at the present stage of development and implementation of modern wastewater treatment technologies.Item Role of biomass resources in promotion of renewable energy(Видавництво Львівської політехніки, 2013) Singh, Tejinder; Dhingra, ArvindThe world especially the developing countries are facing an increasing power crunch. The conventional energy resources are fast depleting and there is an urgent need to find out new avenues of energy to cater to this increasing demand. It is here the energy from biomass finds its place. Although we have been using energy from biomass since the time man learned to burn wood for energy but with the growing technological innovations this energy can be harnessed to meet the growing energy demands. On a worldwide scale Biomass contributes about 12% to today's primary energy supply, rising between 40% and 50% in most developing countries. Biomass fuel obtained from purpose-grown energy crops as well as forests and agricultural waste are being used in power plants and it is very competitive in price and quality with fossil fuels. Applying biomass technology is both an environmental and human necessity, whether on a local scale to get rid of slurries, waste and refuses, or on a global scale to reduce carbon dioxide content in the atmosphere and hence reduce global warming. Scientists are busy in developing different ways of converting biomass into a form that meets our energy needs, while making best use of the available energy. In this paper an attempt has been made to project the biomass conversion and the new emerging techniques of harnessing power from biomass and also from the other biofuels such as Bio-oil and Bioethanol. Hence an attempt has been made through different techniques in this paper that in developing country like India, how much emphasis need to be given on such renewable energy sources for preservation of conventional sources of energy.
