Waste cooking oil (WCO) that is not managed optimally will harm the environment and human health. However, WCO can be recycled into valuable products. In this paper, appropriate WCO management is designed to minimise the cost of collection to a recycling centre as raw material for other products. The post-use products were analysed for circularity based on economic, environmental, and social aspects. A questionnaire-based survey was used to map community behaviour towards postuse products. Furthermore, the design of the waste collection point is carried out using the Maximal Covering Location Problem (MCLP) and the creation of the retrieval route using the Sequential Insertion (SI) algorithm. This study found a circularity framework for waste originating from households whose presence is scattered in small quantities. This study found phenomena related to community behaviour towards WCO and succeeded in developing the collection points and routes design in two scenarios. The municipal government can utilise the strategy of WCO collection points, and optimal WCO collection routes based on community behaviour to manage WCO waste better. Estimates of the WCO's potential, the costs required to handle, and the financial benefits and opportunities for running a circular economy were also analysed. The results of this study could be a good case study of WCO management, especially to develop economic circularity in developing countries.
