The study investigated the relationship of heating value and physical and chemical characteristics of RDF, from the municipal solid waste of On-nut Composting Plant in Bangkok, Thailand.
They proposed the mathematical model for predicting the HHV. Regression analysis was performed on 14 RDF data samples collected from June 2009 to November 2009. In conclusion, the model based on physical characteristic provides a more accurate prediction to HHV rather than a model based on the ultimate analysis.
