The University of O'Higgins in Chile is developing a biofilter system using biochar to treat wastewater from pig farming. This project, led by Dr. Uri Aceituno, utilizes vineyard pruning waste processed via pyrolysis to create biochar.

The biochar's high porosity is crucial for filtering pig manure, known as purines. The initial phase focuses on optimizing the production process to achieve a pilot-scale biofilter within two years. The project emphasizes interdisciplinary collaboration and aims to enhance nutrient retention capacity. Biochar's role in waste management and climate change mitigation is gaining attention, and the initiative supports a circular economy by reusing agricultural residues.
