Rational use of land resources in the placement of municipal solid waste disposal facilities

Within the framework of this article the criteria for assessment of economic, technological and environmental solutions for realization of waste management measures in respect of the objects, which are at the investment stage of their life cycle, are developed. The scientific and methodological foundations for substantiating the composition of structures in the design of municipal solid waste disposal facilities have been developed. The efficiency assessment of technological solutions of solid waste disposal facilities under the restriction of land plot area is presented. A comparative analysis of technical, economic and environmental characteristics of construction of the most common type of landfills (waste disposal area of 3 ha, annual capacity up to 30 thousand tons) for different structural schemes of organization – without breakdown into operation maps and with breakdown into operation maps with their turn-by-turn construction. The assessment of two constructive schemes of organization of waste disposal sites was based on the factors of environmental impact and cost characteristics of landfill construction. The obtained indicators allowed not only to justify the feasibility and assess the economic efficiency of investments for each construction scheme, but also to identify the redundancy of technological solutions, the use of which led to a significant increase in financial and time costs. Thus, the issue of dividing capital costs into years of commissioning of individual maps of landfills with reduction of one-time costs in the first year of object realization is economically feasible. However, forecast changes in price levels on the date of implementation of each map of the facility, increase in the unit cost of disposal of 1 m3 of waste and reduction in the mass of waste buried on 1 hectare, cast doubt on the economic benefit of a one-time reduction in capital costs.
