Abstract
Abstract In Brazil, the Municipal Solid Waste (RSU, from Portuguese Resíduo Sólido Urbano) is a growing issue faced both in the formal field (regulatory laws) and in management practices concerning social and environmental responsibility of individuals, businesses and municipalities. Among several other components, organic matter corresponds to more than half of the entire amount of generated waste. As a treatment and recycling alternative, home composting can improve the use of this fraction generated by Brazilian households. Therefore, this work aims to implement and evaluate a home composting system in four households. In each residence, a cylindrical reactor of 255L was set up to store the leftovers of fruit and vegetables as they were produced, after which they were mixed and covered with rice hull. The temperature andvolume of the filled reactors were weekly recorded. Final composts were analyzed for the macro and micronutrients presented, and also for their maturity stage. As a result, it was possible to reduce the amount of waste allocated for public management by means of this recycling source. The efficiency of the process was evaluated based ontemperature monitoring and absence of unpleasant odors. After 90 days since the end of the process, three of the researched households were found to continue the composting system, voluntarily.
