Calculations were carried out with respect to the division of the whole life cycle into

-    production (with further division into metallic and other materials),

-    operating period (with further division into materials and media),

-    distribution, and

-    finał disposal.

The results of the characterisation phase and the normalisation phase for analysed machines, with reference to the functional unit, are presented, respectively, in Tab. 5 and Tab. 6.

The results of the environmental analyse of chosen objects show that the most environmentally friendly machinę is the PCGf02. The environmental burden caused by PCGbOl is about 70% and by PCGiOl is about 20% greater than in the case of PCGf02 (Fig. 2).
