Sustainable Bioenergy: Optimizing Biomass with ML

What is it about?

This study explores the use of machine learning (ML) to predict and improve the quality of torrefied biomass, which is a type of processed plant material used as a renewable energy source. The researchers developed two ML models to predict the durability and mass loss of torrefied biomass. Durability refers to how well the biomass holds together, while mass loss indicates how much material is lost during processing. The models help optimize the torrefaction process, making the biomass more efficient and sustainable for energy production. The study also highlights the potential of ML in enhancing bioenergy processes and contributing to sustainable agriculture and environmental practices.
