Abstract
Abstract The aim of this research is to study theoretical and practical aspects of the ecological and economic losses from the use of solid domestic waste (SDW) as energy resources in the heat power industry of Ukraine. The methodical approaches to evaluating the ecological and economic losses caused by solid domestic waste (SDW) comprise: the developed algorithm, which evaluates the ecological and economic losses in the SDW use as fuel and energy resources in comparison with basic and project variant; the investigated morphological composition of SDW in the Ukrainian regions, on the basis of which there is proposed a matrix for further calculations of the ecological and economic loss from atmospheric pollution as a result of the energy-intensive SDW combustion at the power plants by the Ukrainian regions. The efficiency of using SDW as secondary energy resources, which essentially depends on the conventional energy resources combustion, is proved. According to the chemical and morphological composition of SDW, the average amount of harmful substances by their element constituents of SDW is determined. The economic loss from the combusting 1 ton of SDW as energy resources is estimated. Reasonability of using SDW as energy resources, based on the optimal ratio between conventional resources and energy-intensive SDW through minimizing total production costs and possible ecological and economic loss, is grounded. It is proved that while estimating the ecological and economic losses, it is necessary to consider the SDW morphological composition and regional specific features regarding the location of heat and power enterprises and organized storage landfills. It is grounded that the obtained estimates of the ecological and economic losses may be used for identifying the ecological and economic evaluation of the SDW efficiency use in the heat power industry at the regional level.
Highlights
Under modern conditions of social and economic development, the amounts of the fuel and energy resources (FER) consumption is constantly growing, which leads to the nonrenewable natural energy resources depletion and influences the energy independence of Ukraine and Poland [1]4]
In order to construct the matrix, it is necessary to study the solid domestic waste (SDW) morphological composition by the Ukrainian regions, which enables defining the polluting substances mass, which comes to the atmosphere after combusting 1 ton of every element of the SDW morphological composition
The performed studies enable concluding that efficiency of using solid domestic waste (SDW) as the secondary energy resources greatly depends on the combustion amount of conventional energy resources
Summary
Under modern conditions of social and economic development, the amounts of the fuel and energy resources (FER) consumption is constantly growing, which leads to the nonrenewable natural energy resources depletion and influences the energy independence of Ukraine and Poland [1]4]. The long-term operation of resource and energy intensive industries and technologies, overconsumption and overconcentration of the production in the industrial regions justified the necessity of the alternative energy research One of such directions may include the solid domestic waste (SDW) use in the heat power industry, implementation of which will save natural resources (gas, coal) at the stage of their mining, transporting and consumption, and will reduce the amounts of SDW accumulation on the organized storing landfills, which will reduce the eco-destructive impact on the environment. This objectively determines the importance and necessity to carry out systematic studies regarding the improvement of ecological and economic principles of using SDW in the heat power industry according to the State Energy Strategy of Ukraine till 2030
