Polysuccinimide is widely used in agriculture as a biodegradable and non-toxic soil conditioner. It enhances water retention in soil, improving plant growth and reducing the need for frequent irrigation. In the field of water treatment, it acts as an effective scale inhibitor, preventing the buildup of mineral deposits in industrial water systems. Additionally, it is utilized in the production of environmentally friendly detergents and cleaning agents due to its ability to chelate metal ions and reduce water hardness. In the medical sector, polysuccinimide serves as a precursor for biocompatible polymers used in drug delivery systems and tissue engineering. Its versatility and eco-friendly properties make it a valuable material across various industries.
