A composite indicator for incinerability called incinerability index or i ‐Index has been developed to quantify the incinerability of municipal solid waste (MSW) as a unique numerical figure on a scale of 0–100. Due to the absence of guidelines for the formulation of a composite indicator, the reliability of the quantified incinerability and the incinerability‐based rankings might be debatable. To ascertain the suitability of the methodology in developing the indicator for incinerability, uncertainty, and sensitivity analyses are essential. This article aims to carry out the uncertainty analysis of the various stages of the formulation of i ‐Index, namely, relative weightage determination of input parameters, normalization of parameters and their aggregation. Sensitivity analysis is also done to determine the extent of influence an input has on the quantified incinerability. The robustness and the transparency of i ‐Index can be assessed and improved by this approach.
