Landfill Gas (LFG) recovery is a very important element of an integrated solid waste management. The use of the landfills for solid waste disposal will continue to be the predominant method worldwide. This includes the information on how LFG to energy technologies worldwide can be implemented to extract the energy locked up in the landfills. This contributes the consolidation of knowledge in the field of LFG.Provide an overview of the status and prospects of LFG including the technical aspects and benefits of LFG recovery. Estimate of the methane generation estimation once the empirical constants have been determined by using the LFG models.In the present study, various physico-chemical parameters of the MSW were analysed to characterize the waste dumped at Okhla landfill sites in Delhi, India, which shows that it contains a high fraction of degradable organic components. The decomposition of organic components produces methane, a significant contributor to global warming. Based on the waste composition, waste age and the total amount dumped, a first-order model (FOD) was applied to estimate the methane generation potential of the Okhla landfill site, which yields an estimate of 25.98×106 m3/year.Keywords

An experimental study of the ignition characteristic of solid cone fuel spray for a high speed diesel engine for diesel fuel at various injection pressure (100 bar, 200 bar and 300 bar) is carried out to get the effect of injection pressure on ignition delay and duration of burning. The ignition delay of diesel fuel spray was measured by recording the time delay between the event of ignition and the event of appearance of flame inside the combustion chamber by using digital storage oscilloscope. For this purpose an experimental set up was developed with the emphasis on optical method for detecting flame. The measurement of ignition delay was taken at various cylinder pressures (20, 30 and 40 bar) for different surface temperature (623K, 673K and 723K). Main objective of this project was to study the parameter of emission and their control. The result presented here shows that, ignition delay and duration of burning of diesel fuel decreases with increase with injection pressure and also with increases in hot surfaces temperature and also with increases in cylinder pressure.Keywords

The present study analyses the influence of container size available during foraging on the demographic attributes of ladybird beetle Menochilus sexmaculatus (Fabricius; Coleoptera: Coccinellidae). To provide variations in the foraging arena, we used a small petri dish, large petri dish, and beaker as small, medium and large containers for foraging. Results revealed significant influence of container size on life attributes. Developmental attributes of M. sexmaculatus were better in the small arena followed by medium and large arenas. The highest mortality rate and maximum life expectancy were recorded in a large arena, followed by medium and small arenas. Reproductive attributes (fecundity and oviposition period) were much better in the large arena. The results of this study indicate that a small container encompassing small foraging arena is beneficial for immature development and survival, while a large container encompassing large foraging arena is best for the reproductive attributes of adults.Keywords
