The MSW in Thailand has high moisture content, which it can become the RDF should reduce the moisture content of MSW.
The Biodrying technology is appropriate for pre-treatment of the waste to RDF, which found that Biodrying to make the moisture content of MSW is decreased from 73.0% to 48.3% when It was through the Biodrying process ( Li-Ming Shao et al., 2010). An important parameter of Biodrying reactor was moisture removal out of the system ( Ardeh et al.,2010). Which the parameters that are control the process consist as follows: aeration, temperature of process, initial moisture of Bio-waste, and temperature with relative humidity of the input air (F. J.Colomer-Mendoza et al.,2012). This system is the best process to removal moisture of waste, it had potential improved MSW becomes high-quality RDF. (Zhang et al., 2009b).
