In this paper the results of investigations on using new BioCo2 polymer binders in a form of thermodynamically stable polymer compositions are presented, together with the indication for its possible application as moulding sand binding agents. Moulding sands bound with the BioCo2 binder hardened by microwaves or under an influence of a temperature are characterized by a compression strength [...] of an order of 2 MPa and a bending strength [...] of an order of 1 MPa, after 1 hour of sample maturing (storing). In addition, binders in moulding sands are reversible (renewable) in this part, which was not completely overheated and the spent sand is easily knocked out, thus enabling recycling of spent sands. Experimental tests performed in the casting house confirmed the laboratory investigations concerning the use of these binders for moulding sands, and the castings met the qualitative and strength requirements for the selected cast iron grade.
