HOW STUDENTS CAN HANDLE SCHOOL WASTE: A CASE STUDY

HOW STUDENTS CAN HANDLE SCHOOL WASTE: A CASE STUDY

This study challenged a public school community in Brazil to construct a waste management scheme with the aim to divert the maximum possible quantity from the landfill. The method asked for separation of waste into biodegradable material, inert recyclable material and trash. Students operated the system. They produced compost from the biodegradable material on the school premises and delivered the inert recyclable material to reverse logistics operators. Only the trash ended up in the landfill. The separated waste consisted of 38.2% biodegradable food scraps, 42.6% inert recyclable material and 19.2% useless material designated as garbage. The windrows for composting received all biodegradable waste from the school, fruit scraps from a neighboring shop, dry leaves and some small branches from the garden as well as water to control the humidity. Of the 157.7 kg of waste produced per month, the management scheme diverted from the landfill 80.8%. The method is available for imitation elsewhere.Keywords: Diversion of waste from landfills, recycling waste in schools, waste management in schools.

Se desafió la comunidad de una escuela brasileña a montar un sistema de gestión de residuos con el objetivo de desviar del relleno la mayor parte posible. Los residuos se separaron en biodegradables, inertes reciclables y basura. Los biodegradables, que eran los restos de comida, se transformaron en compost en las dependencias de la escuela. Los inertes se repasaron a la logística reversa de la ciudad. Solamente la basura se destinó al relleno. Los residuos colectados consistieron de 38.2% de material biodegradable, de 42.6% de material inerte reciclable y de 19.2% de material no aprovechable que se designó como basura. Las pilas de compostaje recibieron, además de los restos de comida, frutas descartadas de una tienda vecina, hojas secas y ramos pequeños del jardín y agua para mantener la humedad. Se demostró que los alumnos pueden operar el sistema de gestión, inclusive el compostaje. Del total mensual de residuos producidos de 157.5 Kg., el 80.8% fue reciclado. El esquema gerencial está disponible para imitación y multiplicación.Palavras clave: Desvío de residuos del relleno, gestión de residuos en escuelas, reciclaje de residuos escolares.
