The compositional analysis of MSW for incineration is shown in the table below. The incinerator requires a lower heating value of MSW in the range of 11-15MJ/kg for stable operation. The incinerator operator is told that 50% of the paper in the MSW is to be recycled in the future. He is asked to calculate how much plastic could also be recycled without affecting the operation of his plant. What answer does he give? (5 marks). If the plastic recycling rate is targeted at 40%, is the lower heat value of MSW enough to maintain the stable operation of the incinerator? (1 mark) If not, what suggestion do you have to improve the lower heat value of MSW into the incinerator? (1 mark) Comment on your suggestion. (1 mark).
