Abstract The study examined the feasibility of employing technological lignosulfonates as binders in blowing processes to produce small casting cores for shaped iron castings, analogies to the currently in-use Cold-Box Amin procedure. In the study, it has been demonstrated that lignin materials offer several benefits, including workplace safety, within the foundry itself, and in terms of maintaining environmental hygiene in the vicinity of a similar manufacturing facility. It is indicated that the cost of binders could drop twice when using the suggested lignin components. Mixtures with experimental compositions have been proposed and put to the test. The sand-oligosulfonate mixture’s composition has quantitative properties that have been determined. Binders exhibiting stable properties and high strength indicators (up to 3.0 MPa) were developed after processing. The nonionic surfactant class was determined to include the most effective additions. It was experimentally demonstrated that applying specific nonionic surfactant types as technological lignosulfonate modifiers boost and stabilizes properties by a significant order of magnitude (from 0.05 MPa to 0.5–0.7 MPa) %, concerning specific binding ability). Consequently, excellent cast iron castings and a prototype batch of cores were created. A significant emphasis is placed on developing special machinery for lignin binders
