“…From Figure 4, it is found that the growth and dissipation time of pore gas pressure in the field tests are greater than those in the laboratory tests. Under the same gas permeability coefficient, the dissipation times of pore gas pressure calculated by field test fitting parameters were between 50 and 150 years, but those obtained by the laboratory test fitting parameters were only about 1.5 years, which are similar to the results of Ivanova et al (2008) and Liu et al (2011). Moreover, the peak values of pore gas pressure calculated by the fitting degradation parameters from field tests were much lower than those from laboratory tests.…”

The degradation of solid waste in landfills results in the coupled migration of gas and leachate through the pore spaces in waste material. The existing analytical methods cannot be used to obtain a solution for the gas–leachate coupled migration problem. This study used the differential quadrature method to solve the gas and leachate phase continuity equations considering the effect of the gas–leachate coupling. The calculation results were verified based on the calculated data of previous studies. The results of the field gas collection tests and the laboratory degradation tests were fitted using the peak gas generation equation. The peak values of gas generation were found between 0.94 and 20.29 years in the field tests, and between 0.09 and 0.19 years in the laboratory tests. The gas pressure calculated by parameters fitting of the field tests and the laboratory tests were less than 1 kPa and greater than 8 kPa, respectively. Considering the gas-leachate coupling effect, the pore gas pressure in the simulated landfill increased by approximately 20%, and the peak pore gas pressure occurred slightly earlier than that without consideration of the coupling effect.

“…The durations of the five field tests were different. Ivanova et al (2008), Gioannis et al (2009), and Mahar et al (2016) provided related parameters of gas generation from laboratory tests. According to the above field and laboratory data, Equation (26) was used to fit the variation of gas generation.…”

“…The gas composition in both waste samples was similar with the methane content in the range of 58% -62% and the carbon dioxide content 35 -40%. The cumulative gas volume for raw MSW (collected from White's Pit waste processing plant in Southern England) degraded anaerobically for 919 days as reported in [28] was significantly higher (243.55 L kg -1 DM) which is attributable to the higher organic waste composition in the raw MSW. This reduced gassing potential of the MBT wastes demonstrates diversion of the degradable fraction from disposal to landfill as a result of the biological pre-treatment process, but also that landfill gas control measures will still be required to prevent fugitive gas emissions from landfill.…”

Landfill continues to be the major method of Municipal solid waste (MSW) disposal in the UK and many other countries despite considerable efforts to limit its use. The EU Landfill Directive requires, amongst other things, that waste is treated to reduce its biodegradability prior to disposal to landfill. This pre-treatment is often achieved through what is generically termed mechanical-biological treatment. Predicting the biodegradability or degradation potential of these pre-treated wastes is important for the long term management and aftercare of landfill sites. To address this, a series of biochemical methane potential (BMP) tests have been undertaken to characterize the anaerobic biodegradation potential of two mechanically biologically treated (MBT) waste samples in terms of biogas yield, solids composition (loss on ignition, total carbon, cellulose, hemicellulose and lignin contents), and assessment of leachate characteristics during the biodegradation process. Experimental results from a long term study of MBT wastes treated to different standards are analyzed and compared. The relationship between biogas potential and solids composition was investigated, and carbon and nitrogen mass balances are discussed. The biogas potential was shown to correlate well with the ratio of cellulose plus hemicellulose to lignin, loss on ignition and total carbon content of the waste indicating a clear link between these parameters. The results indicate that solids composition of MBT wastes may provide a useful indication of the biodegradation potential. The mass balance indicates that a large proportion of carbon and nitrogen remain locked up in the waste material and is not released.

The energy conversion potential of municipal solid waste (MSW) disposed of in landfills remains largely untapped because of the slow and variable rate of biogas generation, delayed and inefficient biogas collection, leakage of biogas, and landfill practices and infrastructure that are not geared toward energy recovery. A database consisting of methane (CH4) generation data, the major constituent of biogas, from 49 laboratory experiments and field monitoring data from 57 landfills was developed. Three CH4 generation parameters, i.e., waste decay rate (k), CH4 generation potential (L0), and time until maximum CH4 generation rate (tmax), were calculated for each dataset using U.S. EPA's Landfill Gas Emission Model (LandGEM). Factors influencing the derived parameters in laboratory experiments and landfills were investigated using multi-linear regression analysis. Total weight of waste (W) was correlated with biodegradation conditions through a ranked classification scheme. k increased with increasing percentage of readily biodegradable waste (Br0 (%)) and waste temperature, and reduced with increasing W, an indicator of less favorable biodegradation conditions. The values of k obtained in the laboratory were commonly significantly higher than those in landfills and those recommended by LandGEM. The mean value of L0 was 98 and 88L CH4/kg waste for laboratory and field studies, respectively, but was significantly affected by waste composition with ranges from 10 to 300L CH4/kg. tmax increased with increasing percentage of biodegradable waste (B0) and W. The values of tmax in landfills were higher than those in laboratory experiments or those based on LandGEM's recommended parameters. Enhancing biodegradation conditions in landfill cells has a greater impact on improving k and tmax than increasing B0. Optimizing the B0 and Br0 values of landfilled waste increases L0 and reduces tmax.
