Our environmental activities at Avenza

At Avenza, we are committed to the environmental remediation of the site in lots, that will enable the progressive redevelopment of areas.

Our commitment for the environmental remediation and the recovery of the Avenza industrial site

The former Agricoltura plant, covering 17 hectares, is located in the Apuan industrial area of Avenza, in the municipality of Carrara, within the Massa and Carrara Site of National Priority. Production activities at the site, established in the 1940s by the SIR-Rumianca group and conferred by law to Eni (through ANIC Agricoltura) in 1982, stopped permanently in 1984. After the passage to Enichem, in 2004 began safety measures and the environmental procedure for the site's remediation. At present time, as Eni Rewind, in addition to having completed the dismantling of all the old structures, we are committed to soil remediation in subsequent lots in order to progressively make the areas available for new developments, and to groundwater remediation. Since 2023, we have also operated at the adjacent former Italiana Coke site, external to the site of national priority. As of 31 December 2025, we have incurred in environmental costs amounting to €161 million.

Our activities at Avenza

Avenza Former Rumianca

In 2004, we began emergency groundwater safety measures with the construction of a hydraulic barrier and a groundwater treatment plant (GTP). Between 2004 and 2005, we carried out emergency soil safety measures, including covering and waterproofing contaminated areas and draining and collecting rainwater. Furthermore, in 2017, we completed the demolition of obsolete industrial facilities. With the approval of the groundwater remediation project, we strengthened the hydraulic barrier, currently consisting of 33 pumping wells and the existing GTP, increasing the treatment capacity to 200 m³/h. At the site, we are conducting trials for a bioremediation technology that promotes the biodegradation of contaminants (chlorinated solvents) directly in the groundwater. Regarding soil remediation, the project involves excavation and disposal interventions in subsequent lots to ensure the progressive availability of the areas for new developments. The remediation activities were started in compliance with the procedures stated in the operational protocol for the execution and testing of excavations approved by the Tuscany Region and other authorities in 2020 and revised in 2022.

Avenza Former Italiana Coke

In 2024, the company completed the soil characterisation plan and in 2025 submitted a risk analysis for unsaturated soil, which was approved in June 2026 and is currently awaiting the Tuscany Region’s decision. In 2023 the company submitted a groundwater remediation project which is currently undergoing preliminary investigation.

Status of the environmental process

The groundwater and soil remediation projects in Avenza (Rumianca) were approved in 2016 and 2018 respectively. The procedure involving the former Italiana Coke site is currently undergoing preliminary investigations.
