Marchesi Ginori Lisci, the SIAD Group and Solvay announce the construction of a new plant for the production of biomethane and bio-CO2 in Italy.
Today, at the Mining Museum in Montecatini Val di Cecina, in the presence of Regional President Eugenio Giani, Mayor Francesco Auriemma and other national, regional and local authorities, Marchesi Ginori Lisci, the SIAD Group and Solvay officially announced the construction of a new biomethane and bio-CO2 production plant that will help promote good circular economy practices in the area and further decarbonise the activities of the Rosignano plant.
The plant, located on the Marchesi Ginori Lisci estate in Querceto (Montecatini Val di Cecina) and owned by the company itself, will be built to produce 2 million m3 per year of biomethane and 2,500 tonnes per year of bio-CO2.
Solvay has committed to purchasing 24 GWh per year for the next 15 years, replacing part of the natural gas used to power its energy plants with biomethane and reducing CO2 emissions from steam production. Starting in 2026, this renewable energy source will contribute to a reduction in CO2 emissions at the Rosignano site of approximately 8,000 tonnes per year.
For over two centuries, the Ginori Lisci family, owners of the company of the same name, has been a point of reference for the local area, combining tradition, quality and environmental responsibility. The company has evolved over time, remaining faithful to its historical values and constantly investing in sustainable innovation.
"In a rapidly changing world, staying true to your roots also means looking ahead," says Luigi Malenchini, managing director. "Sustainability is not just an ethical choice, but a concrete commitment to future generations and to the community with which we have always had a strong bond."
"All this without ever losing sight of quality, which has always distinguished the brand, and the centrality of people, with company policies focused on the well-being of workers and the promotion of local talent," concludes the company's president, Lionardo Ginori Lisci.
The project exemplifies a circular model in which agricultural by-products are transformed into renewable biomethane and biogenic CO2. The SIAD Group, a leader in biomethane and Bio-CO2 technologies, together with Tecno Project Industriale, a Group company, will build and operate a plant for the recovery and liquefaction of CO2 generated during biomethane production, which will then be transported and supplied to Solvay for use in its sodium carbonate and sodium bicarbonate production processes at its Rosignano site. The biogenic CO2 introduced into Solvay's production cycle will reduce the need for fossil-based CO2 and the overall carbon footprint of the Rosignano site.
Bernardo Sestini, President and CEO of the SIAD Group, explains: "We are convinced that innovation, which has always been one of our hallmarks, is the basis for the development of environmental sustainability. In the biogenic CO2 supply chain, the SIAD Group has developed solutions that integrate engineering know-how with that of industrial gases, enabling the recovery of a waste product and transforming it into a resource for various industries (such as chemicals and agri-food). The recovery and use of carbon dioxide from short carbon cycle processes enables the development of an increasingly circular and sustainable economy.”
This initiative follows the success of the project launched in 2018 by Solvay and SIAD, with the construction of a CO2 capture plant at the Rosignano site to capture CO2 from industrial fumes and reuse 40,000 tonnes of CO2 per year in the production of sodium carbonate and bicarbonate. Both projects contribute to improving Solvay's energy independence, reducing emissions and strengthening the competitiveness and sustainability of the Rosignano industrial park.
