Company History.
AGF was officially incorporated on 18 February 2015, but its history of innovation and commitment to excellence began much earlier. Its majority partner and director, Francisco Guzmán, started out in the Spanish biogas sector before the company was incorporated, contributing his knowledge to biogas plants that were not working or were on the verge of closure. His work in 2014 at the URBILIZA RENOVABLES plant (Biogás – Urbiliza Renovables) marked the beginning of his relationship with Fernando Selva, an active promoter, in love with biogas and suffering the ups and downs of a nascent sector. One of the personalities of the Spanish renewable gas industry, whose tenacity marked some of the milestones of the sector, a pioneering path that once opened many are beginning to travel in recent times.
Both partners decided to develop the first version of AGF’s CIAD. All the applied R&D and knowledge of processes had to be channelled through the creation of an engineering company capable of developing the knowledge generated. The company had to take more and more risks, entering service niches that would allow developers to make their projects a reality. Profitable business in a non-prized market.

From the outset, AGF has been an innovator in the sector, standing out for its ability to adapt and evolve in a constantly changing market. From the initial conception of the project, its execution and operation, to being able to apply its knowledge internationally in more mature biogas markets.
