A review of literature data concerning physicochemical properties and possibilities of practical utilisation of the most important natural biopolymers (proteins, celluloses, starch, chitozan) are presented in the paper. Biopolymers being renewable natural polymers characterised by several required physicochemical properties (adhesivity, activity, no toxicity, biodegradability) constitute more and more interesting processing raw material for various industrial utilisations including environment friendly binding agents for moulding sands. Protein and starch compositions are used as binding agents for moulding and core sands in the foundry industry. Preliminary tests – performed within own research - of modification and utilisation of biopolymers as binding agents for moulding sands are promising from many aspects: technological (adequate properties of moulding sands), ecological (no toxicity, biodegradability) and economic (low price). Starch from the polysaccharide group seems to be especially interesting since it is abundant, easily obtainable, biodegradable and the cheapest polymer. At its actual low price and the possibility of using agricultural wastes in the production, problem of utilising starch in many industry branches can become significant, especially in Poland.
