In a solid waste handling facility, the moisture contents (MC) of food waste, paper waste, and glass waste were found to be MCf, MCp, and MCg, respectively. Similarly, the energy contents (EC) of plastic waste, food waste, and glass waste were found to be ECpp, ECf, and ECg, respectively. Which of the following statement(s) is/are correct?

1. MCf > MCp > MCg
2. ECpp > ECf > ECg
3. MCf < MCp < MCg
4. ECpp < ECf < ECg

Correct answer: MCf > MCp > MCg

Solution

Food waste typically has a higher moisture content compared to paper and glass waste due to its organic nature, which retains more water. Therefore, the statement that the moisture content of food waste is greater than that of paper waste, which in turn is greater than that of glass waste, is accurate.
