· ORCs could generate 67,85,540–81,21,650 kWh electricity per year, equivalent to save 2035–2436 tons standard coal and reduce 7743–9268 tons CO2emission, for a 4000 t/d cement production line. ORCs reduced gas emissions of CO2by 0.62–0.74%, SO2by 3.83–4.59% and NOxby 1.36–1.63%. The PBP (payback period) was 2.74–3.42 years.
The operations leading to the recovery and recycling of CDW have four main benefits: reduced use of natural resources, reduced transportation to and from mining and quarrying sites, reduced energy consumption and reduced volume of CDW sent to landfill (Table 4.1 ).
