Overhauling the cityˈs waste management system



As Sofia, the capital of Bulgaria, grows and modernises, the city is making sure that its waste management system keeps up. This project consists of three separate phases: a landfill for non-hazardous waste, a mechanical biological treatment plant, for which the construction started in the beginning of 2014, and a central heating plant. The two first phases were co-financed under the 2007-2013 Structural Funds Environment programme.

  • Construction of a Mechanical Biological Treatment (MBT) plant at the Sadinata site with Refuse Derived Fuel (RDF) production capabilities.
  • After sorting out bio-waste and green waste, the plant is able to treat all household waste from Sofia.
  • With a capacity of approximately 410 000 tonnes per year, waste treatment operations can run 310 days a year, meaning an average daily treatment capacity of 1 320 tons per day.
  • Creating direct jobs (71+102), as well as non-direct jobs.
  • Utilising organic fraction to obtain a Compost Like Output (CLO), a stabilised compost which can be applied in land remediation processes or as a soil improver.
  • By segregating and finding alternative uses for waste the city is limiting and reducing the amount of waste that would potentially be deposited in a landfill, and reduce potential emissions on the landfill.

The third phase of this project, the central heating plant, is financed under the 2014-2020 Environment programme.
