In this interview, Jerónimo González Cortés, a researcher at Cicytex in Extremadura, Spain, explains how his team has been working on anaerobic digestion for more than 15 years to convert agricultural, livestock and agro-industrial waste into renewable energy. Their research focuses on producing biogas and biomethane while also creating digestate, an organic fertiliser that supports circular economy practices. At the European Biomass Congress, they presented promising results from the use of hemp dust together with pig slurry, as well as ongoing work on olive mill waste, demonstrating how these by-products can be transformed into valuable resources for sustainable agriculture and clean energy production.
