Question

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

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

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.

Answer 1

The Correct Option is B

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.
\[ \boxed{\text{Therefore, the correct answer is (B).}} \]
