Non – hazardous waste landfill – Augusta

The landfill is located within the industrial area of Augusta and receives waste generated
by the Municipality of Priolo and Garallo and neighbouring towns reducing costs and
improving previous waste management solutions. The design provides the construction
of a landfill situated in an area of about 83.000 m², with a disposal capacity of 660.000 m³
serving about 175.000 citizens for 6 years.
Each cell will be waterproofed in order to preserve the environmental matrices equipped
with a double collection system for leachate generated within the landfill, this system
counts with a main upper-network for regular leachate accumulation and a secondary
lower-network which serves as a backup. Leachate collection pipe network counts with
separate sumps where leachate is conveyed by pumping it into two separated steel tanks,
in order to allow separately temporary storage before periodical transportation to final
disposal authorised plants.
The plant is completed by the landfill gas management system for the extraction,
collection and upgrading of the biogas generated by the landfill during operation and

post-closure periods. This system allows energy recovery by converting biogas in a bio-
fuel which can be injected in the natural has grid and eventually be used as a fuel for the

transportation sector. The transformation of bio-wastes into clean energy helps societies
to make progress toward becoming circular economies.
The monitoring of the environmental conditions will be done during the operation and the
post-mortem phases according to the Legislative Decree D.Lgs. No. 36/2003.
