Within the scope of this study aimed at safeguarding our environment, we utilized an economical apparatus to eliminate the leachate present in the landfill of Khénifra, Morocco. This substance, predominantly composed of organic matter, exerts a detrimental impact on the ecosystem. The solution put forth in this research involves employing a flat solar collector to expedite the evaporation process of the leachate, which occupies three substantial basins within the landfill. The results obtained showcase a remarkable enhancement in evaporation efficiency, with the flat solar collector contributing to an impressive 300% increase, thereby significantly reducing the evaporation timeframe when compared to the traditional method employed in the landfill. In the context of our experiment, we observed a noteworthy reduction of 18 days in evaporation duration compared to the natural evaporation process, thanks to the implementation of this solar collector. This straightforward, efficacious, and notably cost-effective technique yields compelling and promising results.
