In 2025, the year begins with the awarding of the integrated contract for the revamping of the waste treatment and recovery plant in the Z.I.R. Tempio Pausania – Sassari, owned by the UNION OF COMMUNITIES OF ALTA GALLURA. Active for over twenty years, the Polo Impiantistico is one of the key references for waste management from the separate waste collections in the area. The investment, as in other cases, is financed with resources from the PNRR, the investment program aimed at accessing European funds from the Next Generation EU.
The contract was awarded to a business consortium consisting of Entsorga Spa and Secit Impianti Srl, a well-established and successful partnership in the construction of the “Le Cortine” plant of Sienambiente, which became operational in 2024.
The goal of this significant renovation project is to achieve new and important environmental and productive benefits, enabling the plant to recover materials and energy even more efficiently, thanks to Entsorga’s innovative anaerobic digestion and Biomethane production technology, the Cow™ anaerobic plug flow digester. In addition to handling the plant’s biological core, Entsorga will also provide its Eagle Cloud™ management assistance package, our predictive control model essential for ensuring maximum performance in the recovery process.
“The site’s renovation, integrating composting with anaerobic digestion, will not only improve the efficiency and sustainability of waste treatment but also offer significant economic and environmental benefits,” commented our CEO G. F. Galanzino. “At the end of the revamping, the treated waste will be transformed into not just a richer compost but also into biomethane, a renewable fuel that significantly reduces greenhouse gas emissions and maximizes the organic waste recovery cycle, closing the recovery loop. In summary, we will reduce waste to almost zero, thus minimizing landfill use and moving toward the environmental goals set by the EU for 2030.”
Once operational, the plant will be able to process up to about 20,000 tons of organic waste, producing approximately 1,700,000 Sm3 of Biomethane and around 4,000–5,000 tons of Compost. The entire treatment process will therefore become even more virtuous, increasing the valorization of organic waste and gaining significant flexibility, essential for managing the seasonal increase in waste due to tourism. Last but not least, it will save the environment thousands of tons of CO2eq per year, thanks to both the savings from waste treatment and the specific CO2 recovery guaranteed by the biomethane production process.
