Guidelines for energy balance assessment

Within the scope of the ENGY project the University of Patras undertook the role of providing guidelines for the energy balance assessment. Life cycle analysis methodologies were used for the assessment of the energy balance.

The life cycle analysis took into consideration:
- the energy consumption
- the material consumption
- the coolant fluid consumption and
- the grinding wheel wear
induced either by the grinding or by the grind-hardening processes. Furthermore, the various handling procedures were considered for the assessment of each process setup.

For each pilot case, the achievements presented during the ENGY project were compared with the benchmark criteria that had been defined at the beginning of the project.

Indicatively, it was shown that:
- the substitution of conventional heat treatment processes with grind-hardening in the bearing industry reduces the seriousness of the environmental damage effect by 45%
- the substitution of conventional heat treatment processes with grind-hardening in the automotive components industry can reduce the seriousness of the environmental damage effect by 35%
- the utilization of optimised grinding process parameters such as multi pass grinding and use of newly developed corundum grinding wheels for the grinding of hardened hollow shafts in the defence industry can reduce effect to the environment from 30 to 60%
- For the case of grinding of hardened gears the changes imposed on the grinding machine and the grinding process resulted in an average energy reduction of 38% and a subsequent environmental damage reduction of ca. 43%
