Stabilisation of sewage sludge and vinasse bio-wastes by vermicomposting with rabbit manure using Eisenia fetida.

Abstract

Changes in the chemical characteristics and biological parameters of Eisenia fetida were assessed by VER using (CO+VE) rabbit manure (Vo) spiked with sewage sludge (SS) or vinasse (V). Seven mixtures were used: Vo, control; Vo+SS at 10%, 30%, and 50% (SS1, SS2, and SS3); Vo+V at 10%, 30%, and 50% (V1, V2, and V3). SS vermicomposts had higher humus, nutrient… (More)
