Grupo Gestcompost is entering a new growth phase backed by Suma Capital and the appointment of Iñigo Bertrand as its new CEO. The company, founded in 2003 and specialised in the treatment and recovery of biowaste for the production of biogas, biomethane and organic biofertilisers, is approaching this stage with the support of the €250 million continuation fund promoted by Suma Capital through SC Infra, its sustainable infrastructure strategy focused on developing essential assets for the ecological transition and the circular economy. 

Since Suma Capital’s entry in 2020, Gestcompost has quadrupled its EBITDA, expanded its territorial presence with new facilities in Belinchón (Castilla-La Mancha) and Lleida, and is currently building a new plant in Valtierra, Navarre. The company has strengthened its operational capabilities and holds a project pipeline aimed at expanding its biomethane production capacity in Spain. 

With three operational facilities and the capacity to process 1.2 million tonnes of biowaste per year, Gestcompost will begin injecting biomethane into the grid during 2026, with an initial output of 75 GWh per year. Over the next five years, the company aims to exceed 1 TWh of annual biomethane production. 

To lead this new phase, Gestcompost has appointed Iñigo Bertrand as CEO. Bertrand brings extensive experience in the energy sector and has spent the past eight years heading Edison Next España, a subsidiary of the EDF Group. His background in business management, energy solutions development, and industrial platform growth will be key to supporting Gestcompost through a phase defined by the execution of new projects, the professionalisation of its management structure, and the group’s consolidation in the Spanish biomethane market. 

Iñigo Bertrand, CEO of Gestcompost, said: “It is a privilege to join a company with the track record, reputation and potential of Gestcompost. The vision developed by Juan Antonio and the team over all these years has created a leading platform in the organic waste recovery and biogas and biomethane production sector.
My goal is to help consolidate Gestcompost’s position in Spain, strengthen the operational plants, and accelerate the development of new biomethane projects. The company has the assets, the team and the support needed to take on this new growth phase.” 

Juan Antonio Solans, the company founder and top executive for the past 23 years, will assume the role of Executive Chairman and will continue to lead teh group´s strategy, business development and institutional relations.  

Juan Antonio Solans, founder and Executive Chairman of Gestcompost, said: “This change in leadership is a natural step in Gestcompost’s evolution. After more than two decades building the company, we are entering a new phase with a solid platform, an exceptional team, and a unique opportunity to contribute to the energy transition through the circular economy. Having a management profile like Iñigo’s is great news for Gestcompost and will allow us to approach this growth phase with the experience and leadership it requires. As Executive Chairman, I will remain committed to the purpose that has always guided us, to our clients, and to the long-term development of the group.” 

Antoni Macià, Partner at Suma Capital, said: “Over recent years we have supported Gestcompost in its consolidation as one of the leading platforms in circular economy and organic waste recovery in Spain. Through SC Infra, we continue to invest in essential infrastructure for the ecological transition and in companies with a solid industrial base, measurable environmental impact, and the ability to scale solutions. Iñigo’s appointment reinforces the leadership needed to develop new biomethane projects and execute the company’s next growth phase.” 

Gestcompost’s growth plan will increase organic resource recovery capacity, drive renewable gas production, and generate organic fertilisers, promoting more efficient resource management and reducing emissions associated with the use of fossil fuels.
