Eni Rewind

What Eni Rewind does

Eni Rewind S.p.A. is the wholly-owned environmental subsidiary of Eni S.p.A., headquartered in San Donato Milanese, Italy, with approximately 1,000 employees and operations across more than 150 sites spanning roughly 3,400 hectares. Founded in 2003 as Syndial (renamed Eni Rewind in 2019), the company provides integrated environmental remediation, water treatment, waste management, and environmental testing services primarily to Eni group companies in Italy and abroad, and increasingly to third-party public entities and private industrial clients. Eni Rewind has deployed over €6 billion in environmental interventions since 2003, manages approximately 200 active construction sites, and operates infrastructure such as Italy's second-largest groundwater treatment plant (600 m³/h capacity) and the Project Nuraghe multi-functional treatment platform handling 800,000 m³ of contaminated materials.

The company's core offering rests on four service lines: soil and groundwater remediation (using proprietary in-situ technologies including ISCO, Two Phase Extraction, Soil Flushing, Soil Vapour Extraction, and phytoremediation); water management (treatment, demineralization, and recirculation of industrial process water); end-to-end waste management cycle services for environmental and decommissioning activities; and chemico-physical environmental testing delivered in partnership with its 30%-owned affiliate LabAnalysis Environmental Science. Technologically, Eni Rewind combines proprietary process IP developed through university collaborations with capital-intensive infrastructure, including a Dynamic Control System that has increased permeate production by 13%, autonomous drone inspection for inaccessible underground sites, and on-site treatment platforms that minimize waste transport and landfill dependency. Approximately 83% of waste managed flows from Eni operations.

The business model is project-based and contract-driven, with revenue generated through long-duration remediation mandates under Italian Sites of National Interest frameworks, corporate environmental compliance contracts with industrial clients, and public-sector tenders. Approximately €1,130 million in environmental costs were incurred in 2025 across major sites (€793M cumulative at Porto Torres, €727M at Priolo, €117M at San Gavino Monreale, €20M at Sa Canna), reflecting the multi-year, capital-intensive nature of the work. The customer base includes captive Eni demand, public agencies (Invitalia, Sogesid, Roma Capitale), and private industrial firms (Edison, Acciaierie d'Italia, Seram, Nerviano Medical Sciences, Kuwait Raffinazione e Chimica). Pricing is not publicly disclosed and the company does not report standalone revenue figures.
