en.Wedoany.com Reported - The pilot plant of Italian startup Resilco Srl – Società Benefit (a benefit corporation) in Busnago has commenced operations. This facility is the first in Italy dedicated to treating specific alkaline industrial residues, scaling up a process previously validated in the laboratory to a semi-industrial level, marking a key milestone in the company's industrialization journey. The company was founded in Bergamo in 2019 by David Callejo Munoz, with Paolo Brazzo, Alessandro Panza, and Marta Cecilia Pigazzini joining in 2023.
The company's technology is primarily used to recover industrial waste with complex compositions, such as fly ash from waste-to-energy plants, steel slag from iron and steel smelting, and flue gas purification dust from industries like ceramics and glass manufacturing. Its process relies on accelerated natural carbonation reactions, a chemical process where carbonates are formed with the participation of CO₂. The system uses CO₂ as a core reactant to achieve the permanent immobilization of hazardous elements within the waste. The process operates under ambient temperature and pressure conditions, and the time required to complete a single cycle is relatively short, offering significant operational convenience.
In terms of performance indicators, this technology offers new possibilities for the sustainability of converting waste into resources. Its waste recovery rate exceeds 90%, thereby avoiding direct landfilling. The treated industrial residues are transformed into secondary raw materials usable in the construction market, including cost-effective and sustainable fillers and binders suitable for the production of mortars, concrete, plasters, resins, and asphalt. Depending on the application scenario, these alternative materials can reduce cement usage by up to 30%, thus achieving emission reduction effects.
CEO David Callejo Munoz pointed out that the Busnago plant allows for the validation of the model's effectiveness under real operating conditions, converting environmental and economic costs into usable resources for the construction industry. The tests currently underway at the site aim to obtain the official "End of Waste" certification. Once material certification is achieved, the startup, headquartered in Caponago (Bergamo), will proceed to promote replicable plant units that can be deployed directly at client company sites.
