Composta Medellín : revolución circular en la gestión de residuos urbanos

Abstract

After reviewing successful experiences of home composting in other countries, this work proposes to implement a pilot program called "Composta Medellín" that promotes on-site rotary composting as a circular economy strategy. The analysis carried out for the research identified that more than 50% of municipal solid waste in Medellín is organic, and its disposal in landfills generates significant environmental impacts and economic costs. Based on this, the main objectives of the pilot program are to significantly reduce the organic waste reaching the La Pradera landfill, foster sustainable habits among citizens, and use the generated compost to regenerate soils and promote food security. It is concluded that this innovative initiative will effectively and sustainably address the waste crisis in Medellín, transforming citizens' habits, reducing waste management costs, and regenerating the city's soils. It is recommended to bring it to the Council to allocate an annual budget and provide incentives to gradually scale up the program.
