The manufacture of carbon black leads to the production of harmful gases. Previously, the Company had to burn up the gas, which involved a cost. With the Electricity Act 2003 permitting the sale of excess power generated by industries, PCBL commissioned power generation units at each of its facilities. The related energy saving and environmental benefits were the key drivers of this initiative. PCBL is the first carbon black company in the world to receive carbon credits from UNFCCC for its Captive Power Plant, at Baroda.
The power generation process recovers and utilises the thermal energy of the waste gas that is produced during the manufacturing of carbon black. This waste gas is then utilised to generate steam, which in turn is used to generate electrical energy.
Value Chain: Turning Waste into Electricity
The excess electricity available after meeting the in-house power demand is exported to the State Electricity Board grid. In a country that is dependent on a fast depleting natural resource like coal for a large part of its power generation, this results in positive contribution to sustainable economic growth, conservation of natural resources, environment and Greenhouse Gas (GHG) emission reduction.
PCBL currently has 76 MW of green power generation capacity. The increasing presence of the power business in PCBL’s revenue profile is likely to provide a cushion to the overall profitability.
