Pernik Municipality is an eligible beneficiary under procedure No. BG16FFPR002-2.004 under priority 2 "Waste" of the POS 2021-2027. The focus of the project proposal is on building a municipal system for separate collection of the entire amount of food and garden biowaste, which is collected through the municipal systems for mixed collection of BO and upgrading the installation for their recycling. Pernik Municipality plans to build municipal systems for separate collection and transportation of food and green/garden waste and to upgrade the existing composting installation, which should cover a new 6660.05 t. providing a capacity to also absorb waste from parks and gardens, which is currently being collected. In this regard, an upgrade of the installation is planned, including: • Composting in the existing tunnel composter, which will allow the treatment of green/garden and wood waste - Branch 1, with a capacity of about 3000 tons per year. • upgrading the existing waste composting plant with a food waste composting module – Branch 2 with a capacity of about 4400 tons per year. For the composting of food waste, an innovative technology has been selected, allowing for an automated, efficient composting process, without the release of odors, based on strict control of parameters and the addition of a specific set of microorganisms. The composting of food waste will be carried out according to a developed sample recipe in containers equipped with a loading elevator, an infrared camera and a process control system.
