The study analyzes the integrated management of solid waste after the approval of the “Plan de Valorización de Residuos Orgánicos e Inorgánicos 2022” (Organic and Inorganic Waste Valorization Plan 2022). It studies the decomposition phases of organic waste considering factors such as landfill age, waste characteristics, presence of oxygen and temperature. To evaluate the biogas potential of solid waste, the “EPA Model” and the “Mexican Biogas Model 2.0” are proposed, underlining the importance of choosing appropriate methods. A connection is made with a study in Iquitos, Peru, which highlights solid waste management in the tropical rainforest, suggesting the generation of compost and highlighting methane (CH4) as the main component of biogas, with opportunities for the energy industry. The use of precise measurement instruments is recommended, considering the economic limitations, and the exploration of other mathematical models to evaluate medium or long term projections.
