    The research project was carried out in "Augusto Lema Enríquez" Market, located at Pujilí canton, Cotopaxi province. The objective was to analyze the current generation of organic solid waste and establish a system of utilization through natural fertilizers production. The methodology was applied through quarting method in order to know per capita production and organic waste percentage, with a directed survey application to a sample of fifty merchants in areas of greater generation to diagnose current situation regarding wasting management. It was found that lack knowledge about correct separation and methods are the main causes of poor management. It was established that, between two areas of greatest organic production, "Fruits, vegetables, greens" and "Prepared foods" sections, organic waste is generated weekly 1062 kg, so through collection and manual weighing it was determined daily value per capita production of organic solid waste is 3.02 (kg/trader.day). By this way, a system was developed to obtain two types of organic fertilizer, at Municipal Government's Forest Nursery, where collected waste that was disposed and composting methods were applied in order to maintain optimal conditions of organic material, there, 250 kg of each fertilizer type was obtained, from which a sample of 550 g was extracted to determine quality through laboratory analysis. With this, the produced fertilizers were qualified as suitable for agricultural use in soils thanks their nutrients: Total Nitrogen 0.13%, Phosphorus 0.13% and Potassium 0.90%. In conclusion, thanks to the implementation of system quality organic fertilizers with optimal nutrient, better characteristics were obtained; however, it must be recognized that they have lower percentages compared to commercial fertilizers due to their natural production and not being enriched with additives, but they have benefits for environmental sustainability, in addition to lower production costs, making them a more viable economic and environmental option for the local community in the long term.
