Resumen

Peru generated 8,215,355 t of municipal solid waste in 2021, of which 57.64% corresponds to organic waste (OW) and 61.28% is disposed of in landfills with multiple management deficiencies, which makes it necessary to seek alternatives to safely treat OW. In view of this situation, composting allows biotransformation, reduction and obtaining biofertilizers that can be applied as a substrate or amendment. The objective of the research was to evaluate the processing indicators and quality of compost derived from urban organic solid waste in Leoncio Prado, Huánuco-Peru. Waste types were evaluated based on Peruvian regulations for waste characterization, process indicators (temperature and pH), physicochemical characterization and quality based on international standards. The results show significant differences for pH, nitrogen, calcium, potassium, copper and zinc; on the contrary, organic matter, % ash, electrical conductivity, sodium and phosphorus showed no differences, the most outstanding being the high pH levels, and the quality of the compost is “Class B” according to Chilean standard 2880. The compost produced is of medium quality and is recommended for use as a substrate or amendment in agriculture after treatment to correct the high pH levels.
