The stated goal is to enable the separation of material “in house,” reducing costs and enabling a higher quality and higher value end product. Contarina Spa of Treviso, an in-house providing company of the Priula Intermunicipal Consortium and the Tv3 Basin Intermunicipal Company Consortium that handles the waste management of 50 municipalities in the province of Treviso with about 554,000 inhabitants, is ready to inaugurate its brand new recyclable waste valorization plant at its Lovadina site.
And what better occasion than the fourth edition of Green Week, a week dedicated to the theme of sustainability? On Friday, February 20, in the presence of the president of the Veneto region Luca Zaia and the president of the Province of Treviso Leonardo Muraro, Contarina president Franco Zanata will inaugurate the new plant designed to sort glass, plastic, cans, paper, cardboard and bulky items.
A plant equipped with three processing lines: one for glass, plastic and cans, one for paper and cardboard and the last for bulky items. A facility that will allow direct and more accurate sorting to obtain higher-value recovered material to be fed into the Conai circuit. “Another step in the company’s important commitment to innovation in the field of sustainability and in the challenge that has always seen us committed to the valorization of waste: transforming what for some is waste, into a resource,” stresses President Franco Zanata. In the first line, thanks to a series of conveyor belts, screens and aeraulic separators, glass and metals are separated from the rest of the waste. And, in turn, the metals are divided between ferrous and nonferrous using an eddy current magnet. The remaining plastic material, on the other hand, undergoes a separation operation through an optical selector, capable of separating Pet plastic from soft plastic and other types of plastics. The second line, in addition to providing manual sorting booths for the removal of any contaminating material, is equipped with disc screen belts that separate paper material such as sheets, newspapers, and wastepaper from thicker cardboard. Finally, as far as bulky waste is concerned, after an initial manual sorting where still useful material such as wood, iron, rigid plastic or other is recovered, the waste is shredded and sent for energy recovery. All the waste from the three lines, then, is treated in the non-recyclable dry waste plant, where secondary solid fuel is produced.
