“…In this way, the biodegradable waste fractions were reduced to particle sizes (< 30 mm) more suitable for evaluating the BMP of MSW [11] and to approximate physical characteristics of wastes affecting flow and the distribution of solutes and microorganisms in landfills [27]. Subsamples of each of the biodegradable fractions were milled (LAB MILL-8000, Gardco, Florida, USA) to a particle size < 1.4 mm and used to measure total solids (TS) and volatile solids (VS) according to the 2540-G method [28].…”

The optimization of degradation processes and the management of leachate and biogas produced in landfills are key aspects for the establishment of more sustainable municipal solid waste (MSW) disposal in developing countries. In this study, biochemical methane potential (BMP) tests were used to evaluate CH 4 production potential and degradation kinetics of fresh waste (FW) and five-year aged excavated waste (EW) samples from a tropical controlled landfill with compositional characteristics of developing countries. BMP tests with reconstituted samples of the biodegradable fraction of both MSW types were performed at three substrate/inoculum (S/I) ratios (0.3, 0.5 and 1.0 g VS substrate g − 1 VS inoculum), and CH 4 generation parameters were determined using the first-order and modified Gompertz kinetic models. After 30-d, the best BMP results were reached at S/I ratios of 0.5 and 1.0, with cumulative CH 4 productions of 528 and 433 mL CH 4 g − 1 VS for FW, respectively; and 151 and 135 mL CH 4 g − 1 VS for EW, respectively. The first-order kinetic model provided a good fit to BMP results for FW, whereas the modified Gompertz model showed a better adjustment to the BMP data for EW. Calculated first-order CH 4 generation rates for FW and EW were in the range 0.19-0.36 and 0.23-0.25 d − 1 , respectively. These results evidence the high biodegradability and CH 4 potential of FW disposed of in a tropical landfill in Colombia and the reduced BMP of EW despite a relatively short period after disposal under conventional landfill operation conditions.

“…This fraction was characterized by a high percentage of fines (due to soil used as daily cover material) mixed with highly degraded organic matter. Plastics was the second largest category in EW, a consequence of both its high proportion in household solid wastes produced in developing countries with low biodegradability [27].…”

“…Conceptual discussions, feasibility studies and pilot scale investigations are being performed to further understand the process of land ll mining for speci ed deposits. Composition and characterization analysis are performed on the excavated waste samples based on age and location and are assessed to determine the energy and material recovery potential [26][27][28][29][30][31][32]. The waste composition in municipal solid waste land ll typically consists of 50-60% of soil-type material, 20-30% combustible components, 10% inorganic components, and a small amount of metals.…”

Landfills are urban stocks and resource reservoirs for potential energy recovery. The purpose of this study is to evaluate the amount of energy that could be recovered from aged waste (around 5 - 20 years old) recovered from landfills. Investigations were conducted on the physical and chemical properties of refuse-derived fuel (RDF) prepared from recovered landfill waste (RLW) in Andhra Pradesh, India. Waste characterization studies included determination of waste composition, proximity analysis, ultimate analysis, and energy content. The moisture content ranged between 25.70 to 31.30%, however, no trend was observed with age. In the ultimate analysis, the percentage of carbon increased from 42.94% to 71.66% with the age of the samples, this is due to an increase in the plastic content over time. The calorific value of the recovered landfill waste ranged from 10.35 MJ/kg to 21.83 MJ/kg. From the findings, it can be summarized that the RDF can potentially be utilized as a feedstock for the recovery of energy from RLW. The results from this study will assist policy makers and local authorities in designing and developing strategies for resource and energy recovery from landfills in different urban cites across the globe.

“…About 80% of the global production of MSW is stored in landfills. Only 20% of this amount is contained in engineered and controlled landfill sites (Caicedo-Concha, Sandoval-Cobo & Whiting, 2016). It is important to ensure appropriate landfill management and regular monitoring so that the undesirable substances are not transferred into other components of the environment.…”
