This study was undertaken to estimate the energy potential of municipal solid waste via creating a relationship between the high heating value (HHV) and the fractions of physical composition of municipal solid waste MSW (% food, % plastic, % paper, % wood, % textile) into the two scenarios, wet MSW (as discarded) and dry (free moisture). The created models have been determined based on the results of analysis the components of the Al-Diwaniyah MSW and then from previous studies which have experimental ultimate analysis (% C, % O, % H, % N, %S) of MSW supporting by the equations and models of previous studies which have been used for HHV calculation. SPSS Statistical software was used to perform the models. For each scenario, the input datasets were 60 cases taking into account the minimization of the data and the average of HHV that result from equations. Four models have been created, two models for each status where R2 was 1.00 and 0.999 for dry and wet situation respectively. However, the equations of verification process showed that the models which depended on the dry fractions are the more accurate. The produced HHV from the dry and wet MSW components in Al-Diwaniyah City is 8655 KJ/Kg and 6440 KJ/Kg respectively (as discarded).
