In an interesting move in India, the country's leading cement company UltraTech Cement Ltd, has decided to set up up waste heat recovery systems at five of its units over the next two years with a cumulative capacity to generate 63 MW power. This will more than double its overall waste heat recovery capacity from 58 MW to 121 MW.
In a recent report from worldcement.com: "The cumulative capacity of 121 MW will potentially cut the company’s CO2 emissions by 0.72 million tpy, reducing the overall carbon footprint of the business. UltraTech is expected to meet 15% of its power requirement from these waste heat recovery systems."
The waste heat recovery capacity expansion is "planned at Kotputli cement plant in Rajasthan, Dhar cement plant in Madhya Pradesh, Hirmi cement plant in Chattisgarh, Gujarat cement plant in Gujarat and Andhra Pradesh cement plant in Andhra Pradesh. The waste heat recovery system at Dhar cement plant, with a capacity of 13 MW, is under commissioning and is expected to be completed by September 2018."
The report says that "UltraTech Cement is one of the earliest proponents of waste heat recovery systems among cement manufacturers in India. The benefits include carbon footprint reduction and Perform Achieve Trade (PAT) benefits, as well as cost benefits with reduction in cost per unit. As fossil fuels become scarcer and power costs increase, waste heat recovery is going to be a strategic option to become environment friendly and establish cost leadership. Cost benefits include reduction in cost per unit of power from INR4 per unit to just INR0.5 per unit."
UltraTech Cement has set a target to reduce its CO2 intensity by 25% by 2021 says worldcement.com, and "the company has identified waste heat recovery as one of the key levers towards meeting this target of reducing carbon emissions from its operations as well as securing a sustainable energy source."
