ENERGY POLICY
We shall strive for continuous energy economy through –
- Formulation of overall energy strategy and targets.
- All round participation of all employees including casual and
contractor labours with total commitment from top management.
- Improved capacity utilisation.
- Upgradation of process, technology and equipment.
- Better plant layout.
We shall maximise the Group’s synergy by way of sharing expertise,
between the units, through inter-unit visits, zonal conference and audit by
expert team.
As a part of our energy conservation and environmental strategy, we are
committed to reduce specific energy consumption by 1% every year by
2010.
