Seguimiento y propuesta de mejora al modelo integral de residuos sólidos del barrio San Enrique de Velasco: manejo de los residuos orgánicos.

Abstract

The general objective of this project is to carry out a follow-up and proposal to improve the use of organic waste in the San Enrique de Velasco neighborhood. For this, a previous diagnosis of the use of the composters was carried out, identifying its main problems. Next, the monitoring of 10 composters was developed, for this the 3 most common composting processes were identified, the difference between these was the type of dry material since they were classified as sawdust (p 1), shavings (p 2) and dry leaves + ashes (p 3). To obtain the information, the following variables were evaluated: particle size, C/N ratio, temperature, humidity, aeration and odor. In the case of compost quality, the parameters were: humidity, granulometry, content and stability of organic matter, electrical conductivity and pH. The results indicated that the presence of mosquitoes and leachate are the main problems in the composting process. The method with the best results was p 2 since the following characteristics were found in it: I. the average temperature was 42.5ºC, II. the C/N ratio (theoretical) was maintained every week at 30:1, III. 50% of the composters that apply p 2 do not have a bad smell since they mix once a week for 30 min. Regarding the quality of the compost of p 2, it was favorable since the pH, temperature, and conductivity were in the appropriate range and presented a percentage of degradability of 60% after 6 months of composting.
