Ecology-economic analysis of the construction of incinerator in Kaliningrad

Abstract

The aim of this paper is the appraisal of the ecology-economic estimation of the construction
of the incinerator in Kaliningrad,The objectives of the investigations are: the estimation of the
ecological aspects of waste incineration in the case of the construction of the incinerator; and
the economic efficiency estimation of the construction of the incinerator.
During the investigations it was proved that the volume of waste will increase during IO years
at an average of up to 9,000 tons. By burning the waste in the incinerator, waste volume
reduction may reach 90 %. This will reduce the charge of the firing ground; the economy of
ground resources at the construction of incinerator will average in comparison with dumps
borrowed in Kaliningrad (that is on the average 56-71 %); this will prevent the pollution of
water; this will sanitize the waste; at thennal neutralization the production of wastes will be
formed such as ashes (13,300 tons a year) and slag (26,600 tons a year).
By subjecting the waste into the incinerator, electricity production will be 89 million kWh a
year. The investment from the construction will be 2,410 million rubles, The benefit from the
realization of electricity is 51,3 million rubles, of slag is 8 million rubles, and of secondary
raw materials is I 38, I 03.6 rubles. The pay back will be achieved in 40 years. To provide the
repayment of the investments for the construction of the incinerator in 9 years, it is necessary
to increase the tariffs by 25% for the population and budget subsidies should be increased by
90%, Also, this study considers a social factor with 70 citizens of Kaliningrad being
interviewed. The survey helped to reveal the public opinion the population towards the
construction of the incinerator. 96% interviewed people regards the question about of the
incinerator positively.
