The technological processes optimization according to the sustainable technology procedure

Purpose: The paper presents a possibility of the optimization includes in the sustainable technology designing and modernization. Design/methodology/approach: To the estimation of the technological processes towards the sustainable technological processes used four environmental criteria. The possibility of the optimum technological process choice was proposed. Findings: The conclusion of the work is the modified sustainable technology (MSTP) procedure elaborated. In this case the BREFs were used as a standard for the technological processes estimation. Research limitations/implications: As a reference unit, except BREF, can be used other standards. One of the possibilities is the sustainable technology creation to which all the analysed technological processes can be related. Practical implications: The work is an example of the least environmental influences technological processes searching. It gives the basis of the sustainable technological processes designing and the life cycle of the technological processes creation and analyse. Originality/value: The paper presents the sustainable technological processes procedure and its modification with regard of the polyoptimization. This article shows the possibility of the computer aid used.
