“…The anaerobic biodegradation of domestic and industrial waste in landfill sites goes through a complex process and therefore it is not easy to estimate the biological conversions involved. Measurements at these sites must be performed carefully taking into account different waste sources such as pharmaceutical residues, plastic products, antibiotics, and complex organic compounds (Wen et al, 2015;Khan et al, 2008;Kumar et al, 2004;Aguilar-Virgen et al, 2011;Aguilar-Virgen et al, 2012;Angelidaki and Sanders, 2004;Stergar and Zagorc, 2002;ISO 11734, 2012;Kolstad et al, 2012;Gartiser et al, 2007;El-Mashad et al, 2012;Angelidaki et al, 2006).…”

-This study presents the environmental evaluation of an abandoned and potentially contaminated landfill using analyses for the presence of heavy metals and for methane generation potential. The site is located in the city of Santiago, Chile, and was used as a rural landfill for domestic, industrial and construction waste until 1978, but is now in a heavily urbanized area and surrounded by houses. Analyses performed on 24 samples taken in and around the site show Potential Methane Generation (PMG) values between 1.6% and 11.3% of maximum projected levels. These low values, compared to those of an active landfill, indicate that waste material stored in the site has a low capacity to generate methane. Concentrations of heavy metals in the surface and deep soil are similar to typical levels for these metals in normal soil, according to international USEPA standards, and do not present imminent risk to human health. The use of the PMG test technique for the study of the health risk of an abandoned landfill is a new contribution to the Chilean evaluation methodology and management program for Abandoned Sites with Potential Presence of Contaminants (SAPPC). As part of the environmental management strategy for the site, two of the five operable units studied were transformed into a park after this study.

ABSTRACT:It is an important content to analyze the uncertainty of emission from greenhouse gases in compiling the emission inventory. Reliable uncertainty estimates can also be used to increase the quality of emission inventories. This paper took the emission of CH 4 from the solid waste landfill in Hefei City in 2014 as an example, and employed the mass balance method to compute its emission. Monte Carlo method was used to carry out the sensitivity analysis and compute uncertainty. Through computing, 95% confidence interval of CH 4 emission from landfill in Hefei City was (1.89~3.40) × 10 4 t. The mean value was 2.61 × 10 4 t with uncertainty range of -27.59%~30.27%. Among all the parameters, the decomposable proportion of DOC (DOC f ) showed the greatest impact on the emission of CH 4 from the landfill and its contribution to emission result was 26.33%. Followed by the degradable organic carbon (DOC) was 26.29%, the amount of solid waste (MSW) was 13.63%, methane correction factor (MCF) was 6.93% and the proportion of methane in landfill gas (F) was 6.58%. The results showed that compared with traditional error propagation method, it improved the accuracy and quality of assessment and provided a scientific basis to improve the quality of inventory as well.

“…The municipal solid waste (MSW) greenhouse gas (GHG) emissions and carbon footprint were chosen as important indicators for evaluating the efficiency of the MSWM system in previous studies (Khoo et al, 2010;Couth and Trois, 2010). Multiple methods, such as the life cycle analysis (LCA), the GHG inventories of the IPCC and the first-order decomposition model (FOD) have been applied for carbon emission analysis, using the data from statistics, laboratory testing and field studies (Kumar et al, 2004).…”

a b s t r a c tMunicipal solid waste management is one of the key subsystems of urban metabolism, which significantly impacts urban carbon cycles. A conceptual model for analyzing the carbon cycle of the municipal solid waste management system was established based on the theory of urban metabolism with regard to urban carbon cycling. The model includes horizontal fluxes, vertical fluxes and carbon stocks of the waste managing processes such as waste collection, transportation, treatment and disposal. The current carbon cycling of the municipal solid waste management system and two other scenarios were analyzed using a Jingmen City case study. The results indicate that the input horizontal flux in municipal solid waste between 1989 and 2004 was 293.47 Gg. Among all of the considered scenarios, the landfill formed the largest carbon stocks; incineration showed the largest vertical fluxes of carbon dioxide, and source separation and integrated technologies decreased carbon emissions by adding new carbon sources to the urban system. Improving municipal solid waste management using techniques, such as waste minimization, source separation, recycling, technical innovations of incineration, compost and digestion of organic waste, landfill mining, etc., could impact the urban carbon cycle by reducing carbon emissions.
