Cirkulazce is a project solving waste treatment by modern technologies in line with the circular economy principles. We plan numerous ways of treating and reusing waste but we prefer to start step by step. Therefore, we divided the Cirkulazce project into 2 phases. In phase 1 (Cirkulazce 1), we have built a plant for plastic and sludge processing on the premises of the Lazce landfill. We have used available modern technologies for the crushing, drying, thermal decomposition and the use of fuels in cogeneration units. Annually, 15,000 tons of plastics and 16,000 tons of drain sludge from sewage-treatment works will be treated.
