Solid state bioconversion (SSB): an effective process for safe disposal and recycling of domestic wastewater sludge as compost

The bioconversion or biodegradation of Indah Water Konsortium (IWK) domestic wastewater treatment plant (DWTP) sludge was evaluated using two-screened compatible mixed filamentous fungi, Trichoderma harzianum Rifai with Phanerochaete chrysosporium 2094, and T. harzianum with Mucor hiemalis Wehmer, b...
