Operations at BALCO involve primary Aluminium production, which is a highly energy intensive process. Therefore, sustainable conduction of business is a high priority for BALCO Management. The objective is to quantify the GHG emissions in its day-to-day operations, in order to help in identifying improvement areas and access its environmental performance against key performance indicators. The programme would also help to plan and implement measures to further reduce the specific emission rate of GHGs from its operations.
Key emission sources are:
- BALCO has coal based captive power generation units with installed capacity of 810 MW. The Power Plants fire fossil fuels like LDO, HFO and coal for generation of power. Direct emissions due to fossil fuel consumption at the captive generation units comprise around 88% of the direct emissions of BALCO.
- The primary Aluminium production at BALCO involves application of GAMI (Pre-Bake) Technology. This technology is more energy efficient as compared to VSS. The emission intensity is around 2.03 tCO2e/tonne of Aluminium. Process emissions during the primary Aluminium production constitute around 6.5% of the direct emissions of BALCO. BALCO has undertaken a CDM project to change over from VSS to prebake technology.
