Suma Capital has won the award for “Best Impact Deal” for its investment in Grupo Gestcompost, a leader in the biogas and biomethane sector in Spain, at the 2025 Private Capital Awards. The awards ceremony, organized by SpainCap in collaboration with Deloitte and IESE Business School, was held on Thursday, July 3 at 8:00 PM at the Madrid Stock Exchange Palace.
The award recognizes the successful closing by Suma Capital of a €250 million continuation fund to accelerate the growth of Grupo Gestcompost and strengthen its leadership in the circular economy. Founded in 2003, Grupo Gestcompost has established itself in Spain as a leading platform for the treatment and recovery of organic waste to produce biogas, biomethane, and organic fertilizers.
Since Suma Capital’s entry in 2020, Grupo Gestcompost, headquartered in Zaragoza, has tripled its EBITDA and quadrupled its workforce, while opening new facilities in Lleida and Belinchón (Castilla-La Mancha). The company processes 1.2 million tons of organic waste annually across its three strategically located facilities in Aragón, Castilla-La Mancha, and Catalonia.
The capital from the continuation fund will support Grupo Gestcompost’s strategic plan, focused on developing and building new biomethane plants, with the goal of surpassing 1 TWh of biomethane production in the next five years.
This transaction is fully aligned with Suma Capital’s strategy of supporting companies and projects that promote the energy transition and the circular economy. The continuation fund, classified as Article 9 under the EU’s SFDR regulation, ensures that its investments promote sustainability and directly contribute to the decarbonization of the economy.
Enrique Tombas, CEO of Suma Capital, stated: “We are very proud and grateful for this recognition. Winning in the ‘Best Impact Deal’ category validates our strong commitment to sustainable investing. At Suma Capital, we believe that private capital plays a key role in the energy transition and the promotion of a circular economy. We will continue to support projects that not only generate returns but also contribute meaningfully to a greener and more sustainable future for Spain and Europe.”
Juan Antonio Solans, founder of Grupo Gestcompost, said: “This recognition highlights the joint work and shared vision we have built with Suma Capital since they joined the project. Their support has enabled us to accelerate our growth and pursue a more ambitious transition to a circular business model, transforming waste into resources and energy, and driving industrial decarbonization.”
This recognition reinforces Suma Capital’s purpose as a transformative actor promoting a capital investment model with positive impact, aligned with the major environmental and social challenges of our time.
