Objective: to compare the treatment of a mixture of sewage sludge with two types of structuring agents, with and without coffee pulp, evaluating the differences in the process and the quality of the final product. Methodology: The treatments with aerobic aerated piles consisted of three control piles composting sewage sludge and shredded pruning remains as structuring material (T, % v/v 35% sewage sludge and 65% structuring material) and three piles with a co-composting treatment with coffee pulp (PL, % v/v 25% sewage sludge, structuring material with 35% coffee pulp and 40% shredded pruning remains), created with an approximate volume of 3 m3;  These were subjected to physicochemical (T, %H, pH, metals), microbiological (fecal coliforms, salmonella and helminths), maturity and stability tests. Results: Show that both treatments achieve a stable biosolid for subsequent agricultural use. The co-composting of sewage sludge mixed with coffee pulp meets quality parameters for use as amendments, being classified as class A according to U.S.EPA parameters, with no difference found in the statistical analysis when comparing the evolution of the process and the quality of the final product between treatments (T and PL). Con el fin de dar un aprovechamiento a los lodos cloacales en Costa Rica y realizar un primer co-compostaje de su clase en el país, se realizó un ensayo de co-compostaje por 150 días en la provincia de Heredia. Objetivo: Comparar el tratamiento de una mezcla de lodos cloacales con dos tipos de estructurantes, con y sin pulpa de café, evaluando las diferencias en el proceso y la calidad del producto final. Metodología: Los tratamientos con pilas aireadas aeróbicas consistieron en tres pilas testigo compostando lodo cloacal y restos de poda triturado como estructurante (T, % v/v 35% de lodo cloacal y 65% material estructurante) y tres pilas con un tratamiento de co-compostaje con pulpa de café (PL, % v/v 25% de lodo cloacal, material estructurante con 35% de pulpa de café y 40% de restos de poda triturado), creadas con un volumen aproximado de 3 m3;  a las que se le realizaron ensayos físico-químicos (T, %H, pH, metales), microbiológicos (coliformes fecales, salmonella y helmintos), pruebas de madurez y estabilidad. Resultados: Muestran que ambos tratamientos logran un biosólido estable para su posterior uso agrícola. El co-compostaje de lodos cloacales en mezcla con pulpa de café cumple parámetros de calidad para su uso como enmiendas siendo clasificado como clase A según los parámetros de la U.S.EPA, sin encontrar diferencia en el análisis estadístico al comparar la evolución del proceso y ni en la calidad del producto final entre tratamientos (T y PL).
