Assemini, a circular best practice

The historic site of Assemini, which combines an industrial complex for the production of soda, sodium carbonate, hydrochloric acid and hypochlorite with salt works for the cultivation of industrial and food grade salt, is a brilliant example of Eni Rewind's implementation of a circular vision. The recovery of soils and waters, sustainable productive activities and the promotion of cultural as well as environmental projects, all combined in a single, integrated project which aims to rebuild a state-of-the-art future, grounded in respect for and protection of the territory and its past. The best practice also includes Eni's Progetto Italia. Specifically, Assemini is home to the "Permanent hub for the development of technologies in the field of renewable energies", providing for the reuse of areas under permanent safety containment, in order to recover soil and build plants for the production of renewable energies. Generated energy will be used to power processing phases of the company Ing. Luigi Conti Vecchi, covering approximately 70% of the asset's energy consumption. Once more with the aim of developing synergies with the territory, Eni Corporate University has signed a convention with the University of Cagliari. The site is also home to a groundwater treatment plant - TAF. Treated water (approximately 1.2Mm3/year) is partly recovered at the inverse osmosis plant, for successive reuse at the plant, for production processes of the Ing. Luigi Conti Vecchi or for sale to third parties.

Assemini for Progetto Italia

In terms of circularity, the Assemini site, which includes the company Ing. Luigi Conti Vecchi, constitutes a best practice in virtue of its extensive sustainability and attention to the recovery of soil, water and waste resources as well as promotion initiatives linked to Eni's Progetto Italia. The site is a hub of excellence, characterised by the harmonious combination of salt and chlorine production activities with the naturalistic value of the Conti Vecchi salt planes.Eni Rewind is currently reclaiming former or discontinued industrial areas of its own property, using the most innovative and sustainable technologies. Following the permanent safety containment of a brownfield, the first photovoltaic plant was built (23 MWp capacity) for Progetto Italia, enabling the generation of power from renewable sources at former or discontinued industrial sites. Specifically, generated renewable energy will feed the processing cycle of salt produced by the company Ing. Luigi Conti Vecchi, covering approximately 70% of the asset's energy consumption. The project also includes the permanent hub for the development of technologies in the field of renewable energies.


The future under way

The productive requalification of Assemini is already under way and is scheduled for completion in 2026. Once completed, the complex will contain:

  • 1

    new industrial plants the property of the company Ing. Luigi Conti Vecchi (Eni Rewind) for the transformation of salt extracted from the salt planes into industrial and food grade products;

  • 2

    The permanent hub for the development of new technologies in the field of renewable energies, including a 26 MWp photovoltaic plant (of which 23 MWp are already operative) built in the reclaimed and permanent safety containment areas which can be boosted with the construction of additional plants.
