Tassullo was founded in 1909 as a miners' cooperative, with the aim of creating opportunities for emplyment in the area, in a challengin period characterised by migration, exploiting the mineral deposits of Scaglia Rossa Trentina. The company is currently based in the area of its first mine, which dates right back to 1909.
In the period immediately following the Second World War, Tassullo became a joint stock company, thanks to growing demand for building products and post-war reconstruction. The company expanded its activity, building new furnaces to bake the Natural Hydraulic Lime and acquiring new quarries.
The 1970s also saw the acquisition of the Società Anauniense Miniera San Romedio, which originally mined black schist, a particular form of sedimentary rock that is rich in aquatic fossil deposits and is a source of ichthyol, a substance with considerable antiseptic properties. The rising popularity of penicillin and other pharmaceutical products had caused a fall in the demand for ichthyol, and the mine was therefore converted to allow extraction of Scaglia Rossa Trentina, a highly desirable marl with a characteristic perfect balance of clay and limestone. The first industrial premixing plant for the production of plaster and mortar for the building sector was also constructed in the 1970s.
In the early 2000s, the company invested in a survey and research project and confirmed the unique geological properties of the site where the ancient Rio Maggiore mine was located, beneath which lies a deposit of hundreds of hectares of pure dolomite. This marked the beginning of the deep extraction of this uncontaminated rock which, when mixed as aggregate natural hydraulic lime, characterizes the high-performance range of Tassullo products.
In line with the brand's values, since 2013 the company has been involved in a unique space regeneration project: Dolomite extraction is designed with a circular economy approach to create customized underground spaces suitable for technological and commercial activities. This has led to important synergies with other companies that choose underground cells as the ideal place to store their products, ensuring energy and land savings with concrete benefits for the environment.
The period of economic crisis hit the Tassullo group heavily and had a profound influence on the story of the company.
It will be 2018 that will bring new blood with innovative development projects in collaboration with Universities and Research Centers, following the acquisition of the company by a solid group of investors, whose majority partner has more than 60 years of experience just in the construction industry. The company Miniera San Romedio Srl is established, which operates on the market under the Tassullo brand, now synonymous with innovation in the development of technical products and systems for construction.
The company is also reviving its project to regenerate mining areas, imagining new scenarios and opportunities for companies that share a clear ethical vision and transforming a production area into a new asset serving a community that is increasingly attentive to contemporary issues of sustainability and responsible development. This is the context in which TERA, the mining ecosystem of Tassullo, was born, the expression of a conscious and ambitious path: to become a multiplier of space, resources, and opportunities.
