Waste management

The company has more than 15 years of experience in the field of household, industrial, inert and hazardous waste management. Our goal is developing sustainable and cost-effective solutions for the handling, treatment and disposal of waste, including waste-to-energy and end-of-life technologies. Our consulting services and completed projects cover the entire range from planning and analysis to design, technical engineering services, financial/economic analysis, tender procurement and supervision to optimization of operation. In the recent past, we have participated in virtually all stages of the development of the national Bulgarian waste management systems.

That included developing the Waste Management Law and preparing feasibility studies and designs for many of the largest Waste management facilities in Bulgaria – including Sofia, Varna, Veliko Tarnovo, Razgrad, Nikopol and others. More recently, we participated in a myriad of small projects for assessing the morphological composition of the municipal waste. Currently, we are participating in several projects financed by EU funds, aiming at reducing the bio-waste via the construction of small-scale MBT plants.
