– Performance of sorting household waste from a 3V collection using a MBT process to recover organic matter

 - 

Quebec Industrial Research Center (CRIQ), in collaboration with Gazon Savard (Saguenay) and its subsidiary Reviterre, MRC Bellechasse, l’Érable, l’Islet, Régie Intermunicipale de Gestion Intégrée des Déchets Bécancour-Nicolet-Yamaska and the City of Saguenay, have carried out a pilot project of mechanobiological treatment (MBT) to evaluate the performance of our municipal solid waste (MSW) treatment chain to value organic matter. This MBT chain makes it possible to efficiently open the garbage bags and to divide the MSW into three different fractions (fine, intermediate and coarse) . A full one-year follow-up was performed using MSW from a two (2V) collection. Using the same MBT equipment tests were also carried out (in summer, autumn and winter) with MSW from a three-way (3V) collection to evaluate the performance to extract the organic matter contained in this waste (3V), as well as the various valuation options of the different MBT fractions.
