CEO, Sustainable Technologies
Bio: Mario A. Rosato is an electrical, electronic, and environmental engineer, as well as a scientific journalist. He built his first home-sized digester in Argentina when he was 16 years old. The son of a university professor and researcher, since his childhood, he learnt to employ sophisticated instruments in his favourite playground—his father’s lab. At the age of 25, he obtained a scholarship to specialise in renewable energies in Italy. At 28, he chose to leave the academic research world and devoted himself to developing industrial solutions. In 1990, he settled in Italy, and in 2000, he moved to Spain.
In 2004, he became the scientific director of Bioenergía Aragonesa SL. In 2006, he patented the AFADS system, a multitrophic bioreactor for wastewater treatment. In 2009, he founded Sustainable Technologies SL with headquarters in Barcelona (Spain), providing laboratory instruments and consultancy services to universities and companies in Spain and Italy. The company moved its headquarters to Portogruaro (Italy) in 2019. Since 2010, he has provided technical training to biogas researchers and professionals in several private institutes in Italy and Spain, expanding this activity to the rest of the world in collaboration with the World Biogas Association since 2022.
Mario A. Rosato has been running a laboratory for applied research and routine anaerobic digestion tests in Italy since 2011. Since 2014, he has been responsible for the column on bioenergy for Agro Notizie, a specialised e-zine catering to Italian agronomists and agricultural entrepreneurs. In 2015, he became a member of the technical commission responsible for drafting the Italian norm on the biochemical methane potential (BMP) test protocol, with his contributions focusing on error propagation analysis and improving both accuracy and precision. In 2018 he published the first edition of “Managing Biogas Plants – A practical guide”, a book summarising his experience in the field and a rational method to design and manage the anaerobic digestion process. The volume was included in Book Authority’s lists of the best 100 books and 20 e-books on chemical engineering in 2022. In 2025 he published “Optimising biogas plants – Squeezing profits from you digester”. In consideration of the worldwide success of “Managing Biogas Plants”, the Editor decided to publish a second edition, updated and expanded, that will be published in February 2026.
