Biodegradable adhesive agents in agriculture are eco-friendly alternatives to traditional synthetic adhesives. Some common types include starch-based adhesives, which are derived from renewable resources and are compostable; protein-based adhesives, often made from soy or casein, which are also renewable and biodegradable; lignin-based adhesives, which use a byproduct of the paper industry and are known for their strong bonding properties; and chitosan-based adhesives, derived from the shells of crustaceans and known for their antimicrobial properties. Additionally, there are bioplastic adhesives made from biopolymers like polylactic acid (PLA) and polyhydroxyalkanoates (PHA), which are compostable and have a lower environmental impact. These adhesives are used in various agricultural applications such as seed coating, soil stabilization, and packaging, promoting sustainability in farming practices.
