Effective knowledge management is crucial in the Waste Management (WM) domain. Accordingly, this paper proposes the OntoWM domain ontology, developed through use of key phases of the Design Science Research Methodology. To demonstrate the OntoWM ontology’s usefulness, it has been piloted through the SmartBin developed for bins collection process currently being used by the Kemaman Municipal Council (KMC). It is to be consequently leveraged for all local councils in Malaysia’s Terengganu State. This pilot project has been implemented as part of the Smart Community program under the Malaysian Communications and Multimedia Commission, representing the first such innovation proposed for Malaysia’s local councils.
