Técnica da compostagem de resíduos sólidos orgânicos como ferramenta de educação ambiental

Abstract

Population growth has increased production of solid waste, particularly those generated in urban households, however, much of this waste is still inadequately destined, and much of it can be reused or recycled. In this way, environmental education combined with composting practices appear as tools to reduce organic solid waste, transforming them into a stable compound, rich in mineral nutrients and humic substances.. Thus, the objective of this study is to teach families in the community to perform the composting technique using organic residues generated in their residences. The study was carried out in the municipality of Sarandi - Rio Grande do Sul, in the community of São Peregrino. This work has a qualitative and quantitative character, in which environmental education was carried out through composting, with 18 community dwellers with ages ranging from 9 to 57 years. For data collection, two questionnaires were applied to the residents, one at the beginning of the survey and another at the end. They were taught how to make a domestic compost, making a slide presentation and after the practice of making. It was observed from the questionnaires that initially the residents did not have much knowledge about the applied questionnaire, and after the accomplishment of the composting practices the second questionnaire showed that they already had more knowledge about solid wastes, organic fertilizers and what is composting and how it must be made. When asked initially if the residents knew the composting practice of the 18 residents only 13 knew, and already in the second questionnaire 17 already had knowledge. It is concluded that the practice of environmental education through composting is beneficial, and that it can be applied with ease bringing positive results to residents and the community, they have learned about solid urban waste, composting and how to make a rope, the questionnaires, slide presentation and composting practices were crucial tools for the success of this technique and the promotion of environmental education.
