Review of environmental impacts with reference to the division into the main stages of packaging machines life cycle shows that the dominating environmental burdens are associated with operating period. Positive environmental impacts of the disposal stage of packaging machines (about 5.5% of all impacts) diminish the consequences of the rest of harmful interactions (Fig. 4).
