Sa Piramide

We carried out permanent safety measures at the former landfill site, which was used in the past fordisposal of waste from the nearby industrial area.

From the remediation of the former landfill site to new projects for the area

Sa Piramide is a name given to an area that was used for the disposal of residues from zinc and lead production at the nearby Portovesme metallurgical hub, which became part of Enirisorse (Eni Group) in 1978. In 1999, the hub was acquired by the Portovesme company, with the exclusion of the former landfill site. This was subsequently sold by Enirisorse to Singea and, following the merger by incorporation, to Syndial (formerly Enichem). Eni's environmental company, which owns an area of 47 hectares at Sa Piramide in the Sulcis Iglesiente Guspinese Site of National Priority, has undertaken at the former landfill permanent safety measures that were certified by the province of Southern Sardinia in 2022. For the valorisation of the area, a project was submitted for the realisation of a Plenitude photovoltaic park of approximately 4.5 MW on the top part of the permanent safety measures.  

Our activities at Sa Piramide

The former Sa Piramide landfill site was declared obsolete in 1992 at the end of its operation. Safety measures included covering it with HDPE sheeting, filling it with soil and vegetation, regulating rainwater, collecting leachate in a storage tank and discharging it to the water treatment plant at the adjacent factory. Following some problems with the surface insulation, Eni's environmental company, in agreement with the Sardinia Region, prepared and presented a remediation project with permanent safety measures in 2001. Work began in 2004 and was completed in 2009. Eni Rewind currently manages the post-operational phase, with a 30-year duration, with maintenance and monitoring.
