Description and outputs |
|
Describe the main purpose / aim of your activity / project. What were its side effects or secondary results? | This is the building of a former coal-fired boiler house, which is currently being rebuilt into a modern biomass heating plant combining photovoltaics and heat pumps. It also has gas cogeneration units as a backup. The hot water pipeline leading from Cirkula supplies hot water to two housing estates with more than 2,000 inhabitants, while two more stages of its expansion are being prepared. The Cirkula re-use center is also located in the same building, which makes it possible to reduce the amount of bulky waste in the city. Rainwater from the roofs of the Cirkula is also channeled into an underground reservoir, which is used by local gardeners. The circular is therefore a textbook of sustainable approaches in the fields of energy and the circular economy. Benefits: Economic sustainability The heating system applied in the Cirkula energy center is based on the goal of the lowest possible heat price in Slavičín. This is now around 30% lower than the price of heat from gas and is based on the use of local biomass and during the summer on a combination of energy from heat pumps powered by solar electricity; in the same building there is a re-use center, thanks to which we keep the production of bulky waste low (Slavicín has one of the lowest productions of this type of waste - mixed/bulky - in the entire Czech Republic), which also leads to a low landfill fee, which is charged to the city according to of the Waste Act and is formed according to the amount of mixed waste production (the lower, the lower the fee). The biomass heating plant with an output of 2.6 MW will burn an average of 130 truckloads of wood chips per year, thereby providing heat for 2,500 residents in the Malá Pole and Vlára housing estates. This saves approximately 2,700 tons of CO2 compared to heat gain by burning coal. Households sort their waste into collection containers, then take larger volumes to collection yards, where more than half is further separated. The city of Slavičín sorts 550 t of waste annually, of which 100 t is glass, 145 t paper and 100 t plastic. For consistent sorting and reduction of large-volume waste, it has won the "waste Oscar" award several times. Thanks to 346 photovoltaic panels with a total output of 130 kWp, energy from the sun is transformed into electrical energy, which is then used to heat water with the help of heat pumps. A battery storage with a capacity of 100 kWh is used to stabilize electricity production. Excess emission-free electricity is transferred to the distribution network by the substation. Rainwater that falls on the roofs of the complex is collected in a 16 m3 underground water retention tank. The water is then pumped into a small tank, which serves local gardeners to take care of dozens of gardens on an area of 6000 m2. The gas serves as a backup energy source. It is processed in 3 cogeneration units producing both heat and electricity (which further drives the heat pumps). In 2023, gas was no longer used. Not everything we no longer need must be thrown away. From 2022, the Cirkula RE-USE center has been operating in the area of the heating plant and collection yard, which also offers functional items to citizens for further use. Every year, more than 1,000 items that would have ended up in a landfill find their new owners here. The RE-USE project of the Cirkula center was evaluated as the Communal Project of the Year 2022 in the sustainability category. Self-sufficiency Innovativeness Replicability |

Is the activity related to any of your strategical document? | The activity follows the city strategy "Chytrý Slavičín 2022 - 2030", in its final form not only external experts were involved, but also a number of Slavic people involved in five thematic working groups, as well as the general public, who had the opportunity to comment and participate in public discussions. |
Were the implemented activities documented? | As part of the election of Slavičín as the Green Municipality of the Year, an informational video was created in which, among other things, the functioning of the Cirkula complex is described: https:/ /www.youtube.com/watch?v=P8H9Pblc2Uc |
How was the activity funded? | K financování jednotlivých fází projektu Cirkula jsme využili jak dotace, tak výnosy z prodeje tepla. |
Recommendations and inspiration |
|
What recommendations / advice can be deduced from the implementation of your activities and provided to other municipalities with a similar intention? | When creating similar projects, we recommend combining several sustainable principles at once, which will add additional value. It is also necessary to make a really thorough economic analysis before starting a similar project, to take into account the fact that financing is partly dependent on the price of heat and therefore not completely predictable, subsidies may not be flexible enough, etc. We definitely recommend involving relevant stakeholders during the process, including the public, and planning the process of this involvement well. |
Risk, obstacles and positive moments in the implementation process |
|
During the implementation of the activities / project, did you encounter an event that fundamentally affected the implementation? | As a result of the war in Ukraine, the price of the commodity heat rose sharply, and thus it was difficult to finance the project as it was intended - e.g. the extension of the heat pipe, etc. This makes the whole process longer and more expensive. |
Media, promotion |
|
How was the communication with the media and what were the media outcomes? | There have been many articles, TZ, etc. about the Cirkula complex, we attach this one here for an idea: https://www.mesto-slavicin.cz/redakce/index.php?xuser=874485341201242917&portal=1075&lanG=cs&slozka=317473&preview=yes&verze=151062 |
