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 have proposed the mathematical model for predicting the HHV, which the Regression analysis was performed 14 sampling data of RDF
14 samplings of RD F by 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
