The second life ofalga spirulina starts from Siena but is about to arrive in other Italian suburbs. Already known to the food and pharmaceutical industry, it is now transformed into an urban regeneration tool e protection against pollution.
In the district of the Sienese and Florentine Valdelsa, where it is made 80% of the Italian production of motorhomes, high-tech start-ups applied to the circular economy and urban regeneration are growing. New electric batteries, thermal accumulators, green hydrogen, appliances and solutions for the sanitization of environments, cogeneratori green these are the achievements of this new reality of small businesses that are joining together to create the “Tuscan workshops for innovation”, in line with the objectives of the European Green Deal and the long-term decarbonisation to 2050.

Right here, inside 3 old regenerated industrial plants, well have been implanted 100 km of plexiglass tubes where previously osmotic and ozonated water flows inside (so there is no need to use any type of pesticide) and spirulina algae. Now, the three warehouses, instead of emitting fumes, “eat” CO2 and emit oxygen. A new green resource for our industrial areas on the outskirts of the cities.The first series of patents reached the end of the process, in fact, is the one that allows the production of micro algae, including spirulina, using photobioreactors, combined with hydroponic crops, biomass energy cogenerators (mowing and pruning that usually go into the bins) with zero emissions, direct current, LED grow light systems that reproduce the light of the solar spectrum from dawn to dusk.
The company that gave life to the Italian photobioreactors for the automated production of microalgae, managed by an artificial intelligence system, is Nature EssenceThey are the only ones in Italy to produce microalgae in “closed pond” industrial type photobioreactors with a continuous cycle capable, once the plants are completed, of producing about 450 kg / day of dry organic spirulina product Made in Tuscany, a capable quantity to revolutionize the entire Italian market, now mostly dependent on Chinese imports.
«There are many of our patents in these plants, we started with spirulina but we can grow all selected algal strains. They are microscopic photosynthetic organisms considered real green biofactories because they consume only Co2 and mineral salts abundant in nature, in addition to energy. They are used in nutraceuticals and also in pharmaceuticals, they could also be our food of the future, they certainly have a neutral if not positive ecological footprint “, he explains. Fabio Cervelli, the engineer father of over 300 patents who is the basis of the whole operation that is being born in the Valdelsano district.
