The document summarizes the current research of the Environmental Biotechnology and Renewable Energies Group led by Dr. Héctor M. Poggi-Varaldo. The group conducts research in areas such as biological hydrogen production from solid wastes, wastewater treatment, soil remediation, and groundwater treatment. It also examines the microbial communities involved in these processes using molecular biology techniques. The group has collaborations with researchers in Mexico, Spain, Italy, France, and Brazil.
