Abstract
VILLAMIZAR, Salvador; MATURANA-CORDOBA, Aymer; BUSTOS, Carlos A. Pacheco- and SOTO-VERJEL, Joseph. Scoping coupled to the Conesa methodology for the environmental assessment of an advanced system of landfill leachate decontamination. Ing. compet. [online]. 2022, vol.24, n.2, e20911359. Epub May 26, 2022. ISSN 0123-3033. https://doi.org/10.25100/iyc.v24i2.11359.
Landfill leachate is an effluent generated by the degradation of solid waste and the percolation of rainwater, which carries organic and inorganic substances, it is characterized as a dark-colored liquid with toxic, dangerous, pathogenic, and other compounds. It has been shown that the use of advanced oxidation processes coupled with biological treatments achieves effluents with low hazards. Despite benefits generate by these combinations, usually, the researcher’s goals focus just on the effluent, skipping the environmental impact generated in the construction, start-up, and maintenance of the treatments, resulting in a knowledge gap because there is not enough bibliography of works that develop combination between Scoping and Conesa methodology over coupled treatments used in leachate decontamination, in the environmental impact quantification. Considering the last, in the current manuscript was determined the impacts on the biotic, abiotic, and socioeconomic components, generated for coupling a photocatalytic system with a biological process. The Scoping technique was used as input of the environmental impact quantification through Conesa’s methodology. The main result was that environmental impacts produced by leachate leaks, waste generated, and energy consumed are considered as critical in the treatments, and futures researchers working in this field should control, prevent, or mitigate. Finally, the presence of positive impacts of the treatments such as the increase in the availability of water resources due to the effectiveness of the treatment carried out, and compliance with the Sustainable Development Goals is highlighted.
