The MSW or organic waste have higher moisture (60%-65% wet basis) can be used Bio-drying for reducing the moisture of this waste. However, other materials such as degradable or organic compounds may also have suitable for Bio-drying.
A potential limitation of what is suitable for Biodrying is that
the dryer bulking agent tends to have carbon-to-nitrogen (C/N) ratios higher than desirable for composting. This means the material to be Bio-drying must have lower C/N ratios so the final C/N ratio of the mix is appropriate for composting. Values of Bio-drying parameters are similar to those of composting. Table 1 shows the recommended values for Bio-drying parameters.
