Incineration (also called waste-to-energy) is a combustion process where oxygen is used at high temperature to liberate the energy in the waste. A refuse-derived fuel (RDF) compromises of 60% mixed paper, 30% mixed plastic, and 10% textiles. Assume it is completely dried before combustion. Determine the volume of air (in L) at 20 degrees Celsius, 1 atmosphere pressure that is required to combust 1kg of the RDF.

Use the values from table to determine the molecules of C, H, S, and O in the waste, the molecular weights of C,H,S and O are, 12,1,32,16g/mol
