The goal of this article is to application of non-silica sands based on alumininosilicates as an alternative of traditionally used chromite sand for alloyed steel and iron castings. Basic parameters as bulk density, pH value of water suspension, refractoriness, grain shape of the testing sands were evaluated. Also mechanical properties of furan no-bake moulding mixtures with testing sand were determined. Finally, the influence of non-silica sand on casting quality was evaluated via semi-scale under normal casting production for sand characterization Optimization of production process and production costs were described.

Sand samples with furan binder were prepared using Sand, Furfuryl Alcohol and Toluene Sulfonic Acid with ratio 100:0.85:0.30. To

identify and quantify gases releasing from furan binder various studies like FTIR, TGA and GC-MS were carried out. After analyzing our

materials using above mentioned characterizations the chemical formula of the Resin and Binder and amount of gases releasing from

composition were confirmed. After studying various reports on pyrolysis process of furan binder calculation of the % of various gases

emitting during pyrolysis process of furan was carried out. Sample of gas collected from mold was analyzed using GC-MS. Based on GCMS

measurement various gases emitting from furan sand mold were identified and their amount were calculate and compared with the

international standers of permissible gas emission limits in a foundry. The purpose of this paper is to assist foundries in pollution

prevention by devising clean technologies which maintain or improve the quality of ambient surrounding. This paper aimed at

minimization of pollution of air by using various techniques.
