Question:

Which of the following statements is/are TRUE for the Refuse-Derived Fuel (RDF) in the context of Municipal Solid Waste (MSW) management?

Show Hint

Always remember that RDF is derived mainly from the combustible organic fraction of MSW, and it can be processed into pellets, briquettes, or powdered fuel to improve usability.

  • Higher Heating Value (HHV) of the unprocessed MSW is higher than the HHV of RDF processed from the same MSW
  • RDF can be made in the powdered form
  • Inorganic fraction of MSW is mostly converted to RDF
  • RDF cannot be used in conjunction with oil

The Correct Option is B

Solution and Explanation


Step 1: Understanding RDF.
Refuse-Derived Fuel (RDF) is a fuel produced from various types of municipal solid waste (MSW), primarily after removing non-combustible inorganics like glass, stones, and metals.

Step 2: Checking each option.
(A) False — The calorific value (HHV) of RDF is actually higher than that of unprocessed MSW because inorganics and non-combustibles are removed.
(B) True — RDF can be processed into different forms such as pellets, briquettes, or even powder form to suit industrial applications.
(C) False — The inorganic fraction of MSW is not converted into RDF; it is separated out during processing. Only the combustible fraction is converted.
(D) False — RDF can be co-fired with oil, coal, or other fuels in boilers and cement kilns.
\[ \boxed{\text{Therefore, the correct answer is (B).}} \]
