... age of the landfill is calculated to estimate how long it will take for the said FDS to be fully operational before closing. Based on the results of the division of zone 1 to zone 5 and consisting of 16 blocks that have been described previously and by using the cranyon method as a landfill method, the calculation of FDS can be calculated from each block as can be seen in Figure 12. So the total number of days from blocks 1 to 16 is 3,505 days, rounded up to 10 years. ...

In Italia vivono circa 4 milioni di persone con il diabete e ogni anno ci sono circa 350 mila nuove diagnosi. Le persone con diabete ricevono prescrizioni di farmaci, esami di laboratorio e strumentali e richiedono ricoveri ospedalieri più spesso delle persone senza il diabete. Il diabete è gravato da aumentata mortalità e accorcia la vita...

... Landfills should be able to accommodate disposed waste for a minimum of 5 years of operation. 42 This study proposed a 10-year landfill life span by considering cost-effectiveness, political acceptability, and land availability. To calculate the area required for a landfill, factors such as waste generation rate, population growth, and density of the compressed landfill material were considered. ...
Solid waste disposal is one of the challenging components in integrated solid waste management. Particularly the problem is prominent in cities with rapid population growth and waste generation. Harar, a capital city of Harari regional state located in the eastern part of Ethiopia, covers an area of 19.5 km ² and has a total population of 270 000. Despite the fastest population growth of the city, it doesn’t have a landfill site to accommodate the waste generated and open dumping is in full practice. As an integral part of a solid waste management plan, the construction of a landfill has been suggested by the city municipality. However, the multi-dimensional and conflicting aspect of landfill sitting, which involves environmental, social, technical, and economic considerations, challenges the location of a suitable landfill site. In the current study, we have applied geographic information system (GIS) and analytical hierarchy process (AHP) multi-criteria decision analysis to select a landfill site through minimizing conflicting interests. Environmental and socio-economic factors including well water, distance from residence, land use and land cover, elevation, slope, and wind direction were weighted to develop a suitability index for landfill siting. Experts’ opinion was obtained to rank the aforementioned factors. The required landfill size was determined based on population growth, waste generation rate, and waste volume/year. Accordingly, the suitability index resulted in 3% of the area as highly suitable, and the rest 0.29%, 14.18%, 52.75%, and 29.8% classified as unsuitable, least suitable, moderately suitable, and suitable, respectively. Considering the future trend of waste generation, 16 ha of land located in the eastern part of the city was selected as a candidate landfill site with all the required suitability. The results of this study can be used as an input for decision making in siting landfill for Harar city.
In recent years, it’s been observed that the necessity of engineered landfill around the world has increased. The development and enhancement took place to design the engineered landfill much more efficiently and effectively. Rapidly growing global industrialization is a concerning issue that has made an increment in solid waste generation, due to which we require more number of landfills through which we can contain and control the landfill leachate more effectively. The main problem faced by the engineers and planners in landfill is controlling and monitoring the generated leachate. Investigate such developments is a concerning issue for engineered landfill, in this paper, we have compiled various recently published research papers to put forth a meaningful conclusion regarding the new technologies/methodologies. In this paper, we also have compared the journals and respective publishers, which are highly used for paper publication based on engineered landfill, and analysis shows which journal published more technologically enhanced research paper.KeywordsLandfill linerSolid wasteEngineered landfillMethodologiesLeachate
In terms of solid waste management, landfills are the favored disposal strategy. Before an area is established as a landfill, certain crucial things must be focused on and acted upon. In its most basic form, a landfill is a location where trash is “thrown” or “dumped.” However, developing a landfill necessitates a great deal of engineering expertise. A sanitary landfill is an engineered technique for disposing of solid waste on land that is designed to cause the least amount of environmental harm and inconvenience. As a result, the sanitary landfill design includes a detailed description and plan that ensures the safe and effective disposal of solid waste. This chapter goes through the types of sanitary landfills and the critical design requirements. Site selection, landfill liners, landfilling technology, and landfill cover system up to closure stage are all part of the sanitary landfill design. Every part must be properly designed; otherwise, the ecosystem will suffer. Because a sanitary landfill is a site where solid waste is disposed of in an engineered manner, the environmental effect is reduced or eliminated.
