Implications Of Variable Waste Placement Conditions For Msw Landfills, Jason T. Cox, Nazli Yesiller, James L. Hanson
Implications Of Variable Waste Placement Conditions For Msw Landfills, Jason T. Cox, Nazli Yesiller, James L. Hanson
Civil and Environmental Engineering
This investigation was conducted to evaluate the influence of waste placement practices on the engineering response of municipal solid waste (MSW) landfills. Waste placement conditions were varied by moisture addition to the wastes at the time of disposal. Tests were conducted at a California landfill in test plots (residential component of incoming wastes) and full-scale active face (all incoming wastes including residential, commercial, and self-delivered components). The short-term effects of moisture addition were assessed by investigating compaction characteristics and moisture distribution and the long-term effects by estimating settlement characteristics of the variably placed wastes. In addition, effects on engineering properties …
Determination Of Specific Gravity Of Municipal Solid Waste, Nazli Yesiller, James Hanson, Jason Taylor Cox, Danielle E. Noce
Determination Of Specific Gravity Of Municipal Solid Waste, Nazli Yesiller, James Hanson, Jason Taylor Cox, Danielle E. Noce
Civil and Environmental Engineering
This investigation was conducted to evaluate experimental determination of specific gravity (Gs) of municipal solid waste (MSW). Water pycnometry, typically used for testing soils was adapted for testing MSW using a large flask with 2000 mL capacity and specimens with 100–350 g masses. Tests were conducted on manufactured waste samples prepared using US waste constituent components; fresh wastes obtained prior and subsequent to compaction at an MSW landfill; and wastes obtained from various depths at the same landfill. Factors that influence specific gravity were investigated including waste particle size, compaction, and combined decomposition and stress history. The …
