Changes in Characteristics and Physicochemical through Vermicomposting of Pome Sludge by Epigeic Earthworm E. eugeniae

Abstract:

The aims of this study was to investigate the characteristics and physicochemical changes of vermicompost during composting of palm oil mill effluent (POME) sludge processed by epigeic earthworm (E. eugeniae) within 60 days. The value of macronutrients, micronutrients and heavy metals and pH in vermicompost comes out to be (pH8.3), carbon (C) (45.2%), CN ratio (18.1%), phosphorus (P) (5.02%), ferum (Fe) (0.6%), copper (Cu) (16.8 ppm), zink (Zn) (119.54 ppm), mangan (Mn) (1049.86 ppm), potassium (K) (0.81%), nitrogen (N) (2.5%), calcium (Ca) (11.42%) and magnesium (Mg) (2.99%), and was compared with compost from EFB-POME sludge and compost from mesocarp fiber-POME sludge. In addition, the amino acid content in vermicompost detected was very low as compared to raw POME. Meanwhile, three types of fungus were detected in vermicompost which are from Paecilomyces sp., Fusarium sp. and Penicillium sp. The results suggested that POME sludge could be recycled to form compost by using vermicomposting technology, as well as act as a good organic fertilizer.
