Stadler designs and installs high-efficiency MRF and compost refinement plants
Greek renewable energy company Terna Energy, part of the Gek Terna Group, is a leading player in clean energy production and the largest investor in Renewable Energy Sources in Greece. It further consolidates its role in sustainable development and circular economy through its integrated waste management projects. For this area of its activity, the company has chosen Stadler, the globally active German company specialized in the planning, production and assembly of turnkey recycling and sorting plants, as strategic partner in Public Private projects for the design and installation of Materials Recovery Facilities (MRF) in the Epirus region and now also in the Peloponnese. Stadler has now completed the commissioning and start-up of the latest facility, an MRF and Compost Refinement Plant in Tripoli, the capital city of the Peloponnese region, and two further projects in Sparta and Kalamata are in progress.
The new facility stands out for its high degree of automation and efficiency, and for its capacity to adapt to changing material composition. It produces consistently high-quality output, achieving outstanding recovery rates – above 90% for the organic fraction, plastic containers, bottles and paper, and 80% for biofilms and PE film. It is also designed to facilitate maintenance, with easy access to all components and motors for service.
The sorting plant receives mixed Municipal Solid Waste (MSW) with an input capacity of 30 to 40tph in a single line. It is processed to produce a high-quality output of recyclates and organic material. The former – PET, HDPE, PP/PS, Foils, Paper, Cardboards, Ferrous and non-Ferrous cans and containers –are sorted into automatic bunkers then baled.
The process begins with two trommel screens then a Stadler STT5000 Ballistic Separator that separates the rolling, flat and screened fractions. At this stage of the process, Pellenc ST COMPACT optical sorters, seamlessly integrated with Stadler’s high-speed conveyors, come into play to sort waste by material and color on the two main lines: 2D for flat objects such as mixed paper, cardboard and film, and 3D for hollow objects such as bottles, containers and trays. These sorters, which feature Pellenc ST’s latest advanced technology, are perfect for the task with their compact size, low energy consumption and high level of performance, as well as their capability to manage the volumes and variations in the feed.
The entire project unfolded to the satisfaction of Terna Energy, as expressed by Diomidis Kamoutsis, Project Manager, who appreciated “Stadler’s solid design and quality equipment, together with the effective management of the project in all its phases – from designing to delivery, construction and commissioning. Their team was always available, fast in responding whenever an issue arose, coordinating and supporting the construction team, effectively collaborating with the other providers and suppliers on site. The fast delivery and installation were impressive.”
