agroresidues

Agroresidues, also known as agricultural residues or crop residues, are the plant material left behind after crops are harvested. This includes parts of the plant such as stalks, leaves, husks, straw, and stubble that are not removed from the field for sale or consumption. Examples of common agroresidues include corn stover, wheat straw, rice hulls, and sugarcane bagasse. These materials are abundant and represent a significant biomass resource globally.

Historically, agroresidues were often returned to the soil to improve fertility and soil structure, or they were burned in fields, a practice that has environmental drawbacks. In recent decades, there has been a growing interest in the valorization of agroresidues, transforming them into valuable products and energy sources. This approach aims to reduce waste, create economic opportunities, and contribute to a more sustainable agricultural system.

Potential uses for agroresidues are diverse. They can be used as animal feed, bedding, or incorporated into compost. More advanced applications include their use as feedstock for the production of biofuels, such as ethanol and biogas, through processes like anaerobic digestion and fermentation. Agroresidues can also be utilized for the generation of bioelectricity, and as raw material for the production of bioplastics, biochemicals, and construction materials. Research continues to explore novel and efficient ways to utilize this renewable resource.
