Solid waste generation and its associated problems is a global phenomenon, in which the world battles with as a result of the difficulty in the quantification and measurement of solid waste. The measurement of solid waste in Ghana can be associated with several challenges. Therefore, this study was conducted with an aim of identifying the challenges in the quantification of solid waste taken into consideration Ghana as a geographic location. This research utilizes the technique of data reduction to investigate challenges of quantifying solid waste. A structured survey questionnaire was administered to 112 experts in waste management to elicit the appropriate data and this yielded a significant response rate of 76.79%. Before subjecting the data to principal component analysis, reliability test of the survey was performed, the adequacy of the sample and the population matrix were all tested and satisfied, this led to the identification of six new thematic challenges of quantifying solid waste in Ghana. The findings of the study reveal that the six critical challenges of quantifying solid waste are; difficulties in separation and categorization of solid waste into quantifiable units, technical setbacks faced by waste quantifiers coupled with the lack of innovations; difficulties in method(s) of measuring solid waste; danger to the health of waste quantifiers or measurers; resources and logistics inadequacies; Poor policies and legislature guiding the measurement of solid waste.
