In recent years, man has significantly increased the production of solid waste. In addition, the lack of awareness of this problem has limited the possibility of consolidating a culture of environmental conservation. The study sought to promote solid waste management through research as a pedagogical strategy in the school. It was guided under the qualitative approach, with a participation action research design. Techniques were used as field diary and participant observation. The analysis unit consisted of one hundred and twenty (120) students from the Rodrigo Vives de Andreis educational institution in Zona Bananera, Magdalena. The results showed that through the process of inquiry the students became aware of the environment, which was reflected through talks on pollution, solid waste management and recycling. In addition, they designed cartons of cardboard that they distributed to the institution to collect and separate them.
