September 2015

Aktor announces the inauguration of a state of the art project in its field, theIntegrated system of solid waste treatment facilities of Sofia Municipality’.             Aktor in a consortium with Helector, both companies of Ellaktor Group, has entered into the specific contract on late December 2013 with Sofia Municipality. The Project was completed within 21 months, which is an achievement given the size of the project in full compliance with the contractual time schedule. The processing capacity of the MBT Facility amounts to 410.000 tons per annum of mixed Municipal Solid Waste (MSW) and constitutes one of the largest waste treatment facilities worldwide. The project fully covers the waste management needs of Sofia Municipality with a population of about 1.2 million. The MBT plant is constructed on a site of 106.204 m2 and the total built up area of the buildings reaches 29.700m2.

The treatment process incorporates state of the art technologies making the MBT plant one of the most modern MSW facilities in Europe.

MSW are received and treated through process lines which are fully automated and optimized according to the special characteristics of the input waste and are designed for residue minimization and product maximization.

The products are recyclable materials, high quality Refused Derived Fuel (RDF) and non-standard compost (CLO) while residue is material suitable for sanitary landfilling.


The construction and operation of the MBT Facilities is in full compliance with European legislation regarding waste management and environmental regulations. The technical solution applied achieves minimization of the residues that needs to be diverted to landfill, production of useful by-products, avoidance of hazardous residuals, minimization of CO2 emissions and positive carbon footprint.


The project will provide the city and the citizens of Sofia with increased social benefits while being a state of the art landmark project, it will be used as a model for future waste projects both in Bulgaria and the European Union.
