TECHNICAL AND ECONOMIC ASSESSMENT OF DESIGN VARIANTS OF TECHNOLOGIES OF ENVIRONMENTAL PROTECTION ACTIVITIES
The alternative variants of draft schemes for asphalt mixing plants with dust collecting devices are considered. To assess the economic efficiency of dustcollecting equipment at asphalt plants, an asphaltconcrete installation with a singlestage dust collector was adopted. The nomenclature, the amount of pollution and the charge for pollutant emissions under the three treatment options compared are considered. The following graphic dependencies were obtained: net present value indicators on the discount rate; NPV of fuel cost reduction options; net present value of the third option from additional investments; for the field of economic feasibility of the third option, depending on the payment for prevented emissions.
