Abstract
Sanitary city cleaning is one of the most important sanitary and hygiene events, promoting protection of human health and environment. Sanitary cleaning includes a complex of works on solid municipal wastes (SMW) collection, transportation, deactivation, processing and burial and urban territory cleaning. In order to improve the works on SMW handling and the ecological state of urban territories, enterprises of public and utility sphere operate, organizing all types of works listed above. However, processes of waste creation and accumulation are dynamic in their essence. Process of waste transportation depends on various factors. Management of this process often demands urgent correcting of earlier taken decisions or even cancellation of those decisions. Reasons of such changes could be of the most unpredictable nature, for example, traffic jams on motorways, vehicles breakage, repair works on the roads, etc. Thus, the enterprise (or, more precisely, the facilities serviced by it, the transport) acting with the purpose of providing ecological safety to urban territories, is the source of E pollution by itself. One of the main stages of SMW handling is waste transportation, where sources of E pollution with wastes (accumulation points) and enterprises on handling SMW are involved. That is why the solution of the pressing issue of increasing ecological safety of urban territories on the basis of ecologically efficient and energetically economic selection of engineering-ecological system of SMW transportation is represented in the article.
Highlights
Creation of whirlwind growing amount of wastes [1,2,3,4] is a problem of the majority of countries of the world, since it is connected with the necessity to provide for ecological safety of urban territories, creation of favourable conditions for well-being of the population, sanitary cleaning of urban territories, environmental protection and preservation of resources [3, 5,6,7,8]
That is why in the complex of ecological problems a special place is taken by the necessity to create a system of wastes management based on simulation of ecologically efficient and energetically economic solid municipal wastes (SMW) handling on the stages of collection, transportation and utilization of wastes, providing for ecological safety of urban territories
Since presently there is a significant choice of various technological solutions for collection of SMW which could be used for the same urban conditions, for choosing of optimal variant it is necessary to be guided by determination of two criteria, in accordance with the reviewed physical model of the process of decrease of E pollution [29, 30, 42, 44]: ecological efficiency and energetic economy
Summary
Creation of whirlwind growing amount of wastes [1,2,3,4] is a problem of the majority of countries of the world, since it is connected with the necessity to provide for ecological safety of urban territories, creation of favourable conditions for well-being of the population, sanitary cleaning of urban territories, environmental protection and preservation of resources [3, 5,6,7,8]. Under the conditions of rational use of natural and energy resources taking into consideration their high value a special meaning is given to the conjugate solution of the issues of provision of ecological safety and energy preservation based on scientifically ground methodological approach to selection at the stage of designing and improvement of the system of SMW handling with the purpose of increase of its ecological efficiency and energetical economy by implementation of engineering-ecological events either from the number of known ones, or by development of absolutely new events, providing, first of all, collection of wastes which, in the end, determines the timeliness of the issue of research
