Degradation of solids during filtration of blackwater in a prototype vermicomposting unit

The ever-increasing quantities of solid waste produced by societies around the world demand better treatment options than the traditional "put it in a hole" option. Technologies that mimic natural processes can often avoid by-products and harmful residues; they also offer sustainability. At the University of Western Sydney (UWS), research work is underway to develop biological waste management technology based on a 'whole-of-waste' approach for managing domestic organic waste and wastewater. The technology uses vermicomposting for treating highly putrescible waste. This paper presents some preliminary results of the treatment of solid waste in a prototype vermicomposting unit designed and developed at the research facility.
