“…These include reduction of waste heterogeneity, improvements on the addition, distribution, and migration of moisture in waste, and increased gas collection efficiencies. Some of the potential improvements mentioned previously have been implemented in a few studies and demonstrated very promising increases in k values, which approached those achieved in laboratory experiments (Budka et al 2007;Yazdani et al 2012;Oonk et al 2013). As suggested by Eqn.…”

Unaccounted factors that may influence the values of k for single landfill cells include the frequency of addition of leachate or septage containing high amounts of microorganisms and nutrients for microbial activity (El-Fadel et al 1996;Budka et al 2007;Faour et al 2007;Barlaz et al 2010a;Yazdani et al 2012;Oonk et al 2013;Zhao et al 2013).

Quantification of parameters influencing methane generation due to biodegradation of municipal solid waste in landfills and laboratory experiments

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.

“…Composting is a process of controlled decomposition and transformation of organic waste under the action of diverse microbial populations (Cheung and Wong, 1983;Inbar et al, 1988;Jimenez and Garcia, 1991;Tuomela et al, 2000;Wei et al, 2000;Wang et al, 2004). It evolves both aerobically and anaerobically (Himanen and Hänninen, 2011;Yazdani et al, 2012;Neumann and Scherer, 2011). This work is based on a simple concept:…”

The activated sludge from the wastewater treatment plant (WWTP) of Tipaza, rich in plant sawdust, and chicken manure from the company Avicola, rich in nitrogenous matter, appears to be perfectly compatible for co-composting. The compost of these two biomasses gives a satisfactory result confirmed by the monitoring of the C/N ratio, a key indicator of the state of composts. Furthermore, the physicochemical parameters and spectral methods are in favor of the development of spreadable compost.
