The management of forestry waste at municipal waste management centers presents technical, environmental, and social challenges due to its accumulation, slow degradation due to its lignocellulosic composition, and limited institutional capacity to transform it into useful resources. From a circular economy and territorial sustainability perspective, this research aimed to evaluate the technical and municipal feasibility of composting alternatives for forestry waste generated at the Center for the Integrated Management of Urban Solid Waste in the municipality of San Lorenzo Cacaotepec, Oaxaca. A completely randomized block design was established with four treatments: soil, soil + lactic acid bacteria (LAB), manure, and manure + LAB. After 140 days, pH ranged from 7.77 to 8.30 and electrical conductivity from 1.19 to 5.50 mS cm⁻¹. The manure-based compost had the highest N, P, K, Mg, and Na concentrations, whereas the soil-based compost had the highest Ca, Fe, and Mn contents. The results enable evaluation of composting as an appropriate technology for the municipal management of forestry waste, with the potential to reduce pressure on disposal sites, generate organic amendments, and strengthen local waste utilization strategies. The study provides evidence applicable to municipalities with limited operational capacity and contributes to the discussion on the social valorization of residual biomass, circular waste management, and territorial sustainability in local contexts.
