One of the first stations in Russia to convert landfill gas into electricity will be built in Kazan
Recultivation of the Samosyrovo landfill on the Mamadyshsky tract has launched
in Kazan. 876.5 million rubles were allocated for the implementation of the
project under the Clean Country federal program of the Ecology national
Representatives of the municipal and republican media were able to get
acquainted with the scope of the upcoming work during an on-site press tour. “One
of our big challenges after the Samosyrovo dump is the KEK landfill. To date,
there are 1 million tons of garbage. But in November-December 2023, when we
complete the work, there will be another green hill that will give us green
energy”, - Ilsur Metshin, the Mayor of Kazan, told reporters.
247,000 cubic meters of waste will be moved
“We continue our work on improving the ecological framework of our city.
This is the second such site after the Samosyrovo landfill. But here we have
set more complex tasks: new technologies for converting landfill gas into
electricity will be used here”, - I.Metshin noted. He reminded the participants
of the press tour that the recultivation of the Samosyrovo landfill was
completed last year, located 50 meters from the KEK landfill.
The Samosyrovo landfill is located on the area of 14.1 hectares and
consists of three cells. The first of them is completely filled and
decommissioned in 2009, the second is 57% full, and the third is empty.
The recultivation of the landfill will be carried out in two stages. The
first stage is technical, within which the landfill body will be brought up to
“On the first cell, we plan to reduce the height of the hill by 7 meters by
moving the ground to the second cell, - said Iskander Giniyatullin, deputy head
of the Executive Committee. - After that, we will be able to level the hills,
cover them with a special membrane, and then plant trees here. In general, the
same works will be carried out as on Samosyrovo hill, which will allow creating
a clean site here.” In total, 247,000 m3 of waste will be moved from the first cell
to the second, and the slopes of both cells will be leveled.
Landfill gas will be converted into electricity – this
is the first such project in Tatarstan and one of the first in Russia
For the first time, new approaches will be used during recultivation to
solving the issue of landfill gas formation.
“The gas formed in the landfill body is mainly methane. It smells
unpleasant, damages the environment and fire hazardous. But it can be used to
generate electricity. To do this, it needs to be collected and cleaned”, -
explained I. Giniyatullin, deputy head of the Executive Committee.
An active degassing system will be installed at the landfill to collect
gas. As of today, 93 vehicles and 18 people are involved in the facility, the
work is on schedule.
The recultivation project also provides for the collection of landfill wastewater.
It will be collected and sent to the treatment facilities previously installed
during the reclamation of the Samosyrovo landfill. After cleaning, the wastewater
will be collected in a special storage pond, from where it will be used for
The biological recultivation stage involves large-scale landscaping of the
entire landfill site.
“This is not our only project aimed at improving the environmental
situation, - the Mayor reminded reporters– A large program is being implemented
in the Vodokanal's activities, including the cleaning of silt fields. We will
continue to pay special attention to environmental issues”.
