· 2. Energy efficiency: Improving energy efficiency is crucial. Waste heat recovery systems can significantly reduce energy consumption. For instance, waste heat recovery in cement plants can lead to a 20-30 per cent reduction in energy consumption. 3. Carbon Capture and Storage (CCS): CCS is a promising technology.
