SMW accumulation sites in bags (other containers) in
one designated place for the whole settlement. Using
this method of accumulation, solid municipal waste
shall be transported to their placement site by loading
them in bulk, often by non-specialized transport.
An example of a container-free accumulation
system for the whole administrative district of the
republic is the Yalchevsky District; there are no
container sites on its territory, the waste
accumulation, and transportation from the population
in all nine rural settlements is carried out according to
the schedule and in bags. There is no container
accumulation on the territory of Alikovsky District.
Poretsky District can serve as an example of a poor
organization of SMW accumulation system; on
average, in each settlement out of eleven (i.e., with
the exception of the Poretsky rural settlement,
providing 35 0.75 m3 containers), there is currently
one container. There is a selective system of waste
containers in Kozlovsky District settlements. Thus, a
number of settlements have neither installed
containers nor arrange sites for the SMW
accumulation. In general, both a containerized and
bulk SMW accumulation system is used in the
district. Also, the method of waste accumulation is
applied individually in each farm with further
transportation to waste disposal sites using tractor
equipment.
These circumstances demonstrate the existing
problem of the organized collection and accumulation
of solid municipal waste, both in many rural
settlements as a whole, or even throughout the entire
municipal district of the republic.
In total, the region has 12 landfills for waste
disposal. In the Chuvash Republic, there is one SMW
processing and disposal SMW, built by the efforts of
Waste Management JSC in 2015 under a concession
agreement with the Cabinet of Ministers of the
republic. The complex consists of a waste disposal
landfill (at least 200 thousand tons per year), waste
sorting and waste processing complexes with a
capacity of at least 150 thousand tons per year. The
amount of investment in the construction of these
facilities amounted to 1.45 billion rubles. The waste
sorting station is capable of separating waste into
more than 20 types of recyclable materials. So far,
this is the only such facility in the Chuvash Republic.
Thus, at present, on the Chuvash Republic,
territory, there are not enough facilities for
processing, recycling waste, as well as facilities that
dispose of waste in accordance with the requirements
of the legislation of the Russian Federation in the field
of environmental protection. It can affect the
environmental condition in the Chuvash Republic and
the formation of unauthorized dumps. Also, due to the
insufficient number of waste disposal facilities
included in the SRWDS (the State Register of Waste
Disposal Sites), waste from some municipal areas is
transported to other areas of the Chuvash Republic,
resulting in a rapid overflow of existing waste
disposal facilities.
Commercial fractions of production and
consumption waste (paper, cardboard, metal, plastic,
etc.), as recyclable materials, are mainly exported
from the Chuvash Republic territory. It is related to
the absence of enterprises that process or dispose
recyclable materials in the republic.
The development of waste processing production
in the republic will significantly reduce the export of
recyclable materials outside the republic, increase the
employment of population and improve the
environmental situation in the Chuvash Republic.
In these conditions, it seems relevant to study the
issue of building new waste processing enterprises in
the Chuvash Republic. The author considers it
necessary to radically revise the territorial scheme of
SMW circulation in the Chuvash Republic in favor of
waste processing companies. The separate waste
collection at their generation sites will make it
possible to reduce tariffs for residents of the Chuvash
Republic.
Waste processing enterprises shall be located
closer to the settlements with the highest population
and, accordingly, where more waste is generated. It is
possible to solve similar problems using multi-
objective optimization methods. In this case, the so-
called “ideal point” method should be used (G.L.
Brodetsky, 2010).
The following optimization criteria were initially
defined:
average distance to neighboring district
centers, from where waste is removed (km);
population of nearby settlements (thousand
people);
mass of waste, generated in the settlement
(tons/year).
The distances were determined based on the
Autodispatcher automobile portal of cargo
transportation, the population size and the mass of
generated waste were taken according to statistical
data. To calculate the “ideal point”, the best distance
value is the minimum - 34.5 km, and in terms of
population and waste size - the maximum values, 273
479 thousand people. and 145,383 tons/year,
respectively.
Then, for each parameter, the sum of deviation
squares (Li) was determined:
