In order to determine the optimal inlet pressure during permeability test of municipal solid waste, the gas permeability test of fresh waste and old landfilled waste under different compaction density was carried out by means of the self-developed gas permeability test device. The effect of gas compressibility on gas permeability and the optimum inlet pressure of gas permeation test were determined. The test results show that when 1～10 kPa is used for the gas permeability test, the pressure difference and the pressure squared difference have a good linear relationship with the gas flow, and the gas compressibility has negligible influence on the gas permeability. The best inlet pressure of fresh waste is 3 kPa, and the best inlet pressure of old landfilled waste is 4 kPa. [ABSTRACT FROM AUTHOR]
