ABSTRACT

The objective of this work was to know the quality of the compost obtained, of the biosolids generated in municipal wastewater treatment plants and a mixture of different organic materials that were obtained from public gardens and to analyze their effect on the yields in some crops. In this way, the quality of soils that have been degraded by agricultural activity and other anthropogenic actions near the capital of Puebla will be improved. Piles of: 2 m wide, 1 m high and 3.5 m long were built, placing 9 m³ of biosolids, it was mixed in a 2:1 ratio. With exposure to the wind and plastic cover or shading, the piles were periodically manipulated by shoveling or turning to aerate them, this phase is the aerobic part that lasted 3 months. The anaerobic phase consists of increasing the temperature and mixing with other organic residual materials, and they were covered for a period of 2 months, this stage is the static part and without movement until maturing or stable.
