ONsite 44 PETplanet Insider Vol. 24 No. 0/23 www.petpla.net Hybrid MSW and packaging sorting plant in Guadalajara, Spain Stadler Selecciona S.L.U. (a subsidiary of Stadler Anlagenbau GmbH) has completed the installation of a new sorting plant at the Torija waste treatment centre. It is part of the Consortium for the Management of Urban Waste of the Province of Guadalajara, which covers a territory of 288 municipalities and 21 associations of municipalities. The Torija centre, managed by UTE RSU Guadalajara, serves the entire province, receiving waste from transfer stations and, directly, from 22 municipalities. The facility includes a sorting plant, a composting plant, leachate treatment and a landfill site. Public company Tragsa was charged with putting the project for upgrading the sorting plant out to tender. The new facility was required to fit within the existing building and process both Municipal Solid Waste (MSW) and light packaging. The tender was awarded to Stadler for its technical know-how and project management capabilities. The new sorting plant installed by Stadler has an input capacity of 40 t/h when processing MSW and 4 t/h when it is working with light packaging. The process begins with trommels and an STT 5000 ballistic separator, Stadler’s all-rounder for separating household waste, mixed commercial waste and bulky waste, followed by three optical sorters for PET, HDPE, Mix and Briks, and sorters for iron and aluminium. The recovered materials are stored and baled ready for sale. The automation of the process with the ballistic separator and optical sorters has improved the recovery rates and efficiency of the sorting plant, increasing its capacity to more than 100,000 t/a of MSW and over 12,000 t/a of light packaging material. A tight schedule for a challenging installation The project started with the dismantling of the existing plant, which took three weeks. The assembly of the new plant was completed in ten weeks, and it was inaugurated on schedule on April 30th, 2023. The project’s key challenge was installing the new facility within an existing building. “This meant that all tasks had to be carried out with a high degree of precision,” explains Antonio Marzal, Managing Director Tragsa Group Guadalajara. www.w-stadler.de
