Organic waste treatment plant with biomethane production – Catania

The digested sludge will be treated for compost production. The main objective of this
project proposal is to limit negative effects on environmental and human health resulting
from the MSW management. The project is in accordance with EU’s objectives regarding
recycling of waste and the reduction of waste landfilling.
For this reason, municipalities have been activated measures to increase the MSW
separate collection in accordance with the first subparagraph of article 32 (1C) of Italian
D.Lgs. 152/2006 and European directive 2008/98/EC.
In accordance with the waste hierarchy established by art. 4 of the European directive
and the purpose of reducing greenhouse gas emissions by landfilling, easier separate
collection and an appropriate waste treatment are planned, in order to produce organic
materials without negative impacts on the environment.
The project is composed of two main working areas inside two existing buildings, located
in Catania’s industrial area.

The activities that will take place in the plant are: waste storage and mechanical pre-
treatment; anaerobic digestion; treatment of the digested sludge; biogas upgrading;

exhaust air and liquid waste treatment.
The project provides waste treatment capacity equal to 57.000 t/year, of which 45.000 t/y
are OFMSW and 12.000 t/y are green waste used as bulking material during the digested
sludge maturation phase.
