This study investigates the development of gravel-gelatin composites as pre-formed monolithic filter elements for borehole wells in unconsolidated sandy aquifers. The composites utilize food-grade gelatin as a natural, biodegradable, and low-cost binder to bond gravel particles into stable blocks, offering an alternative to conventional loose gravel packs that are labor-intensive to install and prone to placement inconsistencies. A systematic experimental approach was employed to optimize key manufacturing paramet...
