6.4.3. The Tufino plant, Italy
The Tufino plant can be seen in (Figure 4.9) This plant is well engineered <strong>and</strong>
housed in relatively substantial buildings. It has to be mentioned that the
mechanical pretreatment stage is housed in separate building. During the
mechanical stage two fractions are produced:
One that is more than 100mm. This fraction is baled as RDF (Figure
4.10) <strong>and</strong>
One fraction that is less than 100mm <strong>and</strong> is sent for the composting
process
