Mirai Investments, an investment and business development family office specializing in SMEs, acquired, at the same time, Excavaciones Mediola. These two new acquisitions located in the Basque Country will allow Mirai to enter a new area of activity: environmental services and circular economy for heavy industry, the energy sector, and the construction industry.
Afesa delivers technically complex solutions across industrial and hazardous waste management, soil decontamination and remediation, and industrial facility decommissioning. In 2025, its turnover was €65 million, and it has a team of 190 people. It operates throughout the Iberian Peninsula and the islands, with flagship projects such as the ongoing dismantling of the Sines coal-fired power plant in Portugal.
Excavaciones Mendiola, specializing in excavation, earthmoving, construction and demolition waste management, had a turnover of €14 million in 2025. It employs 95 people. It operates primarily in the Basque Country and neighboring regions, with examples of major projects such as those related to the High-Speed Rail (AVE) in Burgos and the Basque Country.
The combination of these two companies reflects a clear complementarity. This allows them to offer a comprehensive service throughout the entire lifecycle of industrial, energy, and construction projects across the peninsula and the islands, in a market driven by increasing environmental demands and the transition to a circular economy.
