Waste polyethylene is a non conventional fuel that avoids landfills and has the nominal structure of (C2H4)n by neglecting the CH3 end groups. A waste plastics supplier guarantees a higher heating value for their pure chopped waste polyethylene powder of 40.9 kJ/g, and they note chopped waste paper powder composed of essentially pure cellulose (C6H10O5)n has only a higher heating value of 17.6 kJ/g. Show that the value for the polyethylene waste powder is "reasonable" and indicate why the HHV for the paper waste is so much lower.
