The paper describes the current state of knowledge in a field where change has been driven in foundry molding sand practice due to the increasing requirements regarding environmental protection. These trends must take into account not only the technological quality and economics of their production process, but also the increasingly stringent requirements related to environmental protection. As part of this study, tests were performed in relation to reducing the toxicity of current molding sands with organic binders, so as to develop new organic binders for foundry practice. Molding sands with binders having various contents of furfuryl alcohol were tested. It was shown that reducing the total furfuryl alcohol content in the binder results in lower strength properties of the molding sands in practice. It was also suggested to replace the use of a furfuryl binder with one based on alkyd resin. The final stage of the study was to demonstrate the desirability of using biomaterials as a component of organic binders for foundry molding sands. Compositions: typical synthetic resins and biodegradable materials were designed as binders to improve the quality of the organic binders used with molding sands.
