This research work was carried out in six sawmills in the San Juan. Maynas district, and its objective was to determine and analyze the management and final disposal of solid waste generated in carpentry shops in 2024. The research, due to its approach, was quantitative, prospective and of a descriptive-comparative research level and non-experimental research design. The research had the participation of 30 operational workers, who were present during the application of the data collection instrument. The survey technique was used and a questionnaire divided into 4 indicators was applied: composition, final disposal, impact and regulations. The main results were that the solid waste generated in the carpentry shops in the district of San Juan is predominantly organic (100%), with a majority composition of wood (73.3%) and sawdust (27.6%). The current management of solid waste shows efficient management, with 90% recycling and 6.7% reuse. The final disposal of solid waste in the carpentry shops of San Juan shows a polarized distribution, where 50% carry out sustainable practices (recycling and composting), while 46.7% maintain inadequate practices (landfills). The management of hazardous waste presents significant deficiencies, with 50% of establishments handling this waste informally, while the storage infrastructure shows disorganization in 66.7% of the carpentry shops. The environmental impacts generated by solid waste in the San Juan carpentry shops are mostly low (83.3%) due to the implementation of control and reduction measures, although there is still a medium contamination in water and soil (53.3%). The Jaccard similarity and distance analysis reveals three distinctive groups in the solid waste management of the San Juan carpentry shops, where a group of high similarity stands out (sawmills 1, 2 and 3) with highly standardized practices (distance 0.053-0.105), while the maximum distance found (0.368) indicates significant gaps in management and final disposal methods between the groups. According to the multivariate multiple correspondence analysis, the need for a differentiated approach to improving environmental management is suggested, recognizing that the sawmills are at different stages of development in their environmental and waste management practices.
