The solid wastes delivered to the MSWP are initially pre-sorted
to remove large elements (e.g., furniture, electronics, foil and cardboard)
and then directed to the sorting line, where the waste stream is divided into four fractions: the >160 mm fraction is sent directly into the cabin for manual waste sorting together with the
90–160 mm fraction after preliminary air and magnetic separation;the 20–90 mm fraction, which primarily consists of biodegradable components, is sent to an indoor CU; and the 0–
20 mm fraction is landfilled. All of the wastewater generated in the sorting process (ca 0.7 m3/d) was initially directed to the PP; however, since March 2012, it has been directed to the MP (Fig. 1).
