“…It was observed that carbon content of the waste obtained from the residential areas like sites 10, 22 and 23 and most of the commercial areas like sites 6, 4 and 16 were higher as compared with other areas. The average value of carbon for all the sites was found as 11·1%, which is less than the reported value of 28·2% for Jalandhar City in India (Sethi et al, 2013). The Std was found higher for site 9 as 5·062, and minimum for site no.…”

“…The variation of nitrogen was observed in the range of 0·30-1·10%. The average value of oxygen for all the sites was found to be 0·57%, which is less than the reported value of 1·2% (Sethi et al, 2013). There was not much variation in average percentage of nitrogen among all the samplings.…”

“…The variation of hydrogen content was observed in the range of 0·64-2·66%. The average value of hydrogen for all the sites was found to be 1·2%, which is less than the reported value of 3·7% (Sethi et al, 2013). The Std was found higher for site 20 as 0·668 and minimum for site 5 as 0·76, which indicated that the MSW compositions did not vary much in the market area but varied greatly in the residential area.…”

“…The variation of oxygen was observed in the range of 17·22-67·60%. The average value of oxygen was found as 38·4%, which is more than the reported value of 18·4% (Sethi et al, 2013). The Std indicated that the MSW compositions did not vary much in the market area and varied greatly in the residential area.…”

The objective of the paper is to develop a mathematical model to compute the chemical compositions of the organic portion of municipal solid waste (MSW) using proximate analysis data. The validation of the developed models were done using test of hypothesis and field samples. In the study, MSW samples were collected from 23 different locations throughout the year and chemical compositions of the organic matter were determined such as carbon, hydrogen, oxygen, nitrogen and sulfur using elemental analyser. Proximate analysis such as combustible volatile matter (VM) and ash content were also measured for all the sites. The range of variation in the chemical compositions and proximate analysis were observed as 5·2% ≤ carbon ≤ 21·2%, 0·64% ≤ hydrogen ≤ 2·7%, 17·2% ≤ oxygen ≤ 67·6%, 0·3% ≤ nitrogen ≤ 1·1%, 0·1% ≤ sulfur ≤ 0·37%, 9·3% ≤ VM ≤ 35·5%, 18·6% ≤ ash ≤ 72·1% on dry basis. Various statistical analyses such as standard deviation, mean, P value and F value were also carried out in the study.

“…Even after use, tires maintain their chemical composition and require thousands of years to fully decompose (Humphrey 2011). About 4-5 metric tons of used tires are discarded each year in Jalandhar, Punjab, India (Sethi et al 2013;Kaushik et al 2012). Disposal of the whole tire in landfills or at dump sites may cause an aesthetic nuisance, contamination of the ground, a possible public health hazard, and above all is a wastage of very good resource material (Reddy et al 2010).…”

Performance Assessment of Gravel–Tire Chips Mixes as Drainage Layer Materials Using Real Active MSW Landfill Leachate

Potential of clogging for rubber tire chips, gravel and their relative performance for transmitting high strength leachate when arranged in proportionate layers of relative thickness and in random state mixes of various percentage compared to the case of used alone were studied through column experiments. Comparative hydraulic performance of gravel and tire chips in their different combinations with percentage change (reduction) in COD, TSS, Ca-hardness and TDS concentration levels for the real active high strength MSW landfill leachate with time were investigated. Experiments were performed to simulate conditions occurring at the base of all active MSW landfills, in an attempt to replicate reasonably worst case conditions. Results clearly showed that the combinations ds (scrap tire chips layer thickness)/dg (gravel layer thickness) = 0.25, 0.50 (arranged by relative thickness) and Ws:Wg = 1:3 (25 % tire chips:75 % gravel; mixed by weight friction of each component) were good in term of obtaining initially relatively free drainage. Minor reduction in hydraulic conductivity for fairly longer duration, due to lesser clogging and small reduction in COD, TSS and Cahardness concentration levels were observed for these combinations. These experimental findings may prove to be very useful for the proper design, long term performance and service life of all tire chips-gravel made drainage layers of all the active MSW landfill leachate collection and removal systems.
