Limenet, an Italian startup focused on decarbonization technologies for hard-to-abate industries, has announced a 5 million euro co-development agreement with Fassa Bortolo, a major Italian building materials manufacturer. The partnership aims to develop and scale a next-generation indirect electric kiln designed to significantly reduce emissions from lime production.
The collaboration represents a practical application of Limenet’s technology within one of Europe’s most carbon-intensive sectors. The co-development project will focus on building an industrial-scale kiln with approximately 10 megawatt capacity over the coming two years. According to the company, the electric kiln approach can reduce lime production emissions by approximately 22% compared to traditional fossil fuel-based methods, while eliminating direct combustion emissions entirely.
This partnership follows a 7 million euro equity investment in Limenet completed in December 2025, led by CDP Venture Capital, with Fassa Bortolo participating as a co-investor. Combined with the new development agreement, the total financial commitment between the parties reaches 9.5 million euros, reflecting strong confidence in the technology’s potential for industrial adoption.
Addressing a Critical Decarbonization Challenge
Lime production represents a particularly challenging sector for emissions reduction, as the process involves both energy-intensive heating and chemical reactions that inherently release carbon dioxide. The partnership with Fassa Bortolo demonstrates how cleantech startups can collaborate with established industrial players to transition existing manufacturing processes toward sustainability.
“Questo accordo rappresenta il primo passo fondamentale nel percorso verso la produzione di calce completamente decarbonizzata. L’elettrificazione del processo di calcinazione permette di eliminare le emissioni legate alla combustione dei combustibili fossili,” stated Stefano Cappello, CEO of Limenet. The executive’s comments highlight how electrification can address the combustion-related emissions portion of the production equation.
Broader Implications for European Industry
The Limenet-Fassa Bortolo initiative reflects a growing trend within the European startup ecosystem of developing sector-specific decarbonization solutions. By targeting industries that have historically resisted decarbonization efforts, companies like Limenet address a genuine market need as the EU continues implementing stricter climate regulations and carbon pricing mechanisms.
Building materials manufacturing remains a critical focus area for European industrial policy, representing approximately 5-8% of the continent’s total carbon emissions. Partnerships between venture-backed startups and established manufacturers increasingly serve as a pathway to rapid technology deployment and scaling, particularly in sectors where traditional R&D cycles would delay necessary emissions reductions.
The involvement of CDP Venture Capital, Italy’s national venture capital fund, underscores government recognition of the strategic importance of climate technology innovation within the manufacturing sector. As European industries face mounting pressure to meet 2030 and 2050 climate targets, similar collaboration models between startups, investors, and industrial partners are likely to become more prevalent.
