“…This result provides experimental evidence for improved landfill management to promote MSWs stabilization in SABL. Liu et al [2021] offered a coupled model formulation to analyze landfill stabilization processes. Different recirculation conditions based on a hypothetical landfill site with a high proportion of kitchen waste were explored.…”

“…In addition, the implementation of leachates recycling in landfill with a high percentage of food wastes must take into account the potential loss of landfill gas production and rapid decomposition compaction. This keeps transportation facilities operating near landfills as well as improves the environmental and economic profits of leachates treatment [Liu et al, 2021]. This review aimed to determine the impacts of leachate recycling on solid waste stabilization.…”

In most countries, controlled landfills are currently the most common disposal method for municipal solid wastes (MSWs). Despite many benefits, the generation of heavily contaminated leachate with substantial differences in both chemical composition and flow rate represents a major drawback. The realization of this has compelled authorities to adopt ever more stringent establishment of pollution control requirements. Landfill leachate is a serious problem in the treatments of municipal solid wastes using landfills methods. This leachate is usually heavily contaminated, but little attention is paid to its treatment. Optimal treatment of leachates to completely decrease the harmful environmental impacts is today's challenge. However, the complex composition of leachates makes it challenging to formulate general recommendations. Leachate variability, particularly over time and within sites, suggests that the most appropriate treatments are adaptable, universal, and simple. Landfill leachate is characterized by high biological and chemical oxygen demand and is usually composed of undesirable ingredients such as inorganic and organic pollutants. Landfill leachate varies with landfill age and content, decomposition methods, hydrological and climate conditions. Recirculation of leachate does not affect alterations in the degree of biodegradability of the waste. During landfill operations, recirculation of leachate is often applied to help stabilize landfill degradation. Leachate recirculation is widely used in practical engineering, and recirculation using vertical wells is one of the more effective methods.
