On May 21, a modern biogas power plant was launched at a landfill in the Lviv region of Ukraine, which will provide the production of more than 800 thousand cubic meters of gas per year and "green" energy for about 735 households in the region.
The facility was built as part of a joint project between Naftogaz Ukrainy and the Clear Energy group of companies.
“The development of low-carbon businesses is a strategic choice of Naftogaz. The construction of this object is one of the steps in this direction. I consider it very important that even in such difficult war conditions we still continue to develop and implement such projects. Thanks to the biogas power plant built here, 38 hectares of landfill, emitting millions of cubic meters of harmful landfill gas, will become a source of energy for the surrounding households. According to our calculations, thanks to this object, more than 2 million cubic meters will not enter the atmosphere. methane, which is 30 times more harmful to the climate than carbon dioxide,” said Yuriy Vitrenko, Chairman of the Board of NJSC Naftogaz of Ukraine.
Landfill gas is formed during anaerobic (without air access) decomposition of organic waste residues (food remains, leaves, branches, etc.). Usually this gas is one of the causes of fires and explosions in landfills. Such fires are difficult to put out, because they form and burn not on the surface, but in the depths of the landfill.
“Now the risk of fires at this site, which have already happened in the past, has decreased. The extraction of biogas should also reduce the height of the landfill body - the landfill will settle under its own weight. Therefore, undoubtedly, the Lviv region, as well as families living near the landfill and receiving electricity from this station, will benefit from this facility. The opening of this facility is the next stage in the reclamation of the landfill, the next stage in ensuring the environmental safety of the residents of Lviv and the region," said Maxim Kozitsky, head of the Lviv OVA.
Degassing technology at landfills not only reduces methane emissions, but also reduces emissions of volatile organic compounds (VOCs) and other air pollutants, and eliminates unpleasant odors.
“The reclamation of the landfill in Velikie Gribovichi is a very important project for the city, which we are implementing with the support of European banks. It is part of a comprehensive plan to address the waste problem in Lviv. Currently, technical reclamation is ongoing, which includes the construction of a system for collecting, treating and utilizing landfill gas with the generation of electrical energy. This will improve the ecology in the environment, because the landfill will gradually decrease in volume due to the downloading of methane and other gaseous elements. I am convinced that today's opening of a biogas power plant and work in synergy with Naftogaz and Clear Energy will be a new step in this important matter,” says Lviv Mayor Andriy Sadovyy.
For process reliability, the plant is equipped with Austrian Jenbacher equipment used in biogas projects throughout Europe.
“The station produces 2 million 645 thousand kWh per year, while replacing more than 800 thousand cubic meters of natural gas. This makes it possible to provide about 735 households with “green” electricity and at the same time reduce CO2 emissions into the atmosphere in the amount of about 30 thousand tons per year,” explained Petr Bagriy, co-founder and chairman of the Supervisory Board of Clear Energy Group.
