Suma Capital has won the award in the “Impact Deal of the Year” category for its investment in Grupo Gestcompost, a leader in the biogas and biomethane sector in Spain, at the 2025 Private Capital Awards. The ceremony, organised by SpainCap together with Deloitte and IESE Business School, was held on Thursday, 3 July at 8:00 p.m. at the Palacio de la Bolsa in Madrid.
The award recognises Suma Capital’s successful closing of a €250 million continuation fund to accelerate Grupo Gestcompost’s growth and strengthen its leadership in the circular economy. Founded in 2003, Grupo Gestcompost has become a leading platform in Spain for the treatment and recovery of organic waste for the production of biogas, biomethane and organic fertilisers.
Since Suma Capital’s entry in 2020, Grupo Gestcompost, headquartered in Zaragoza, has tripled its EBITDA and quadrupled its workforce, in addition to opening new facilities in Lleida and Belinchón (Castilla-La Mancha). The company now processes 1.2 million tonnes of organic waste annually across its three strategically located facilities in Aragón, Castilla-La Mancha and Catalonia.
The continuation fund’s capital will be used to drive Grupo Gestcompost’s strategic plan focused on developing and building new biomethane plants with the goal of exceeding 1 TWh of biomethane production within 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 SFDR regulation, ensures that its investments promote sustainability and directly contribute to the decarbonisation of the economy.
Enrique Tombas, CEO of Suma Capital, said: “We are very proud and grateful for this recognition. Winning in the ‘Impact Deal of the Year’ category validates our firm commitment to sustainable investment. At Suma Capital, we believe that private capital has a fundamental role to play in driving the energy transition and promoting a circular economy. We will continue to back projects that not only deliver returns but also contribute meaningfully to a greener, more sustainable future for Spain and Europe.”
Juan Antonio Solans, founder of Grupo Gestcompost, stated: “This award highlights the joint work and shared vision we have built with Suma Capital since they joined the project. Their support has allowed us to accelerate our growth and move forward with greater ambition towards a circular business model that transforms waste into resources and energy, driving the decarbonisation of industry.”
This recognition reinforces Suma Capital’s mission as a transformative player driving an investment model with a positive impact, aligned with the major environmental and social challenges of our time.
