Estudo preliminar do vermicomposto produzido a partir de lodo de esgoto doméstico e solo

Abstract

Domestic waste, a residue generated during sewage treatments, can be stabilized by many chemical, physical and biological processes. However, the stabilized waste (biosoil) currently lacks proper disposal alternatives. A new and promising disposal method is called farm recycling. The use of vermicomposting has shown to be useful as a mean to stabilize domestic waste. The biosoil achieved through this method exhibits high humidity-retaining capacity, good C/N relationship, as well as a satisfactory percentage of humic acid, thus being able to be incorporated into the soil as a conditioner and fertilizer.
