Organized by the Union of Municipalities of Montenegro, patented – advanced, ecological, and cost-effective solutions of Russian experts were presented today at the Chamber of Commerce of Montenegro Galima Jeržanova and Jurija Žuraparova in the field of waste and sewage sludge management.
To interested representatives of municipal utility companies of Montenegrin municipalities, Jeržanov presented the technology of high-temperature gasification of municipal waste, that is, its conversion into electrical and thermal energy.
The purified and cooled gas obtained by the appropriate treatment of waste in the reactor, as he explained, is directed to a gas diesel power plant for the production of electricity and heat, while the inert ash is safely removed and further used in the cement industry. The process takes place at almost atmospheric pressure and does not produce harmful emissions.
At the facility, it is possible to safely treat all solid waste without sorting, except for metals, non-combustible construction material, and batteries. Jeržanov particularly emphasizes that it is also possible to treat medical waste in this way.
The required investment for the construction of a facility that would produce one megawatt of electrical energy ranges between two and three million euros, and the investment pays for itself within three to five years.
Žuraparov presented the use of ash produced from the gasification process in the manufacture of very inexpensive, high-quality next-generation construction products with exceptionally high physico-mechanical properties. Recalling that ancient Roman concrete—known as an exceptionally durable building material that becomes stronger over time, unlike modern concrete—was made using volcanic ash, the Russian expert said that a similar quality effect in construction materials can be achieved by using ash obtained from waste processing.
He explained that in the so-called geoconcrete produced in this way, a process of calcium carbonate formation takes place, mediated by the biochemical activity of microorganisms that play a role in strengthening and self-healing the material throughout its lifespan, which is why it becomes increasingly stronger over time.
Jeržanov and Žuraparov have patented and protected these technologies in Russia, and, as they state, they are fully aligned with EU standards and verified in practice, considering that they are already being applied in Petrovgrad.
After the presentation, numerous questions followed, along with a discussion with representatives of the municipal utility companies of Montenegrin municipalities.
Secretary General of the Union of Municipalities Mišela Manojlović she pointed out that the aim of the presentation was to carry out a preliminary assessment of the technology and the prospects for implementing a pilot project based on it in Montenegrin municipalities, as well as to consider the possibility of eventually forming public-private partnerships for the production of this type of construction material. In that regard, the Union will act as an intermediary in the coming period so that municipalities can obtain all the necessary data to assist decision-makers.
