San Luigi Mill for years attention to the environment, makes use of every scrap material from the extraction of the oil, to generate renewable energy with zero impact. Il Frantoio is also equipped with a photovoltaic system that allows it to be energy self-sufficient.

Husk nut is obtained in a natural and mechanical way using a smashing nut machine, we use no chemical way. This nut is an excellent alternative to the traditional combustible because it's a natural granular combustible (biomass), suitable for heather, chimney and boiler. Actually husk nut is a cheap, ecological and high grade fuel , it reduces smokes and guarantees a longer life and less maintenance fee for the heather.

Water, olive residues (full of humus) plus nitrogen are used in agriculture as natural manure. Advantages are big. Actualy organic manure makes soli more productive; prevent plan disease; allows farms to save money for chimichal fertilizer.

In 2010, we achieved complete energy independence with the construction of a photovoltaic system on the roof of the mill. Covering an area of ​​500 square meters. panels have been installed that develop a power of 45 Kwh. This allows us to get clean electricity that powers our mill and made us a company 100% ecological eliminating the emission of CO2 into the atmosphere during the production cycle of our "Gold Maremma"

Was officially founded in 2009, with the signing of the Statute of the "Keepers of the Farmers Food Communities in Renewable Energy of Tuscany", thanks to an agreement between Slow Food Tuscany, Slow Food Foundation for Biodiversity and COSVIG, the Consortium for the development of geothermal Areas, an organization of public, who for many years engaged in the promotion and implementation of initiatives consistent with sustainable development programs of the geothermal areas and the entire region of Tuscany. Comes to life in Tuscany in the District of Renewable Energy territory straddling the provinces of Pisa, Siena and Grosseto (the so-called "traditional geothermal area"), where, since the early '900, using the geothermal resource for the industrial production electricity. It is part of Mother Earth and is the first world community of food to clean, renewable energy that operates in the food industry and who insist on production methods rather than on the products, and is composed of entrepreneurs who have a priority to environmental sustainability.
