The increasing demand for energy and the decreasing availability of fossil fuel reserves necessitate the exploration of alternative solutions. Biomass waste, particularly abundant in countries like Indonesia, presents a cost-effective and environmentally friendly energy alternative by reducing CO2 emissions. Transforming waste into a more valuable product is crucial, accompanied by an assessment of its ecological consequences. Nevertheless, the recycling procedure often still consumes materials and energy. Previous research on evaluating the environmental consequences of recycling organic waste into briquettes remains limited. This investigation is focused on analyzing the environmental effects of the recycling process for converting fuel husk waste into briquettes. The study was conducted using burnt husk waste generated from the energy production process through husk burning in tofu manufacturing.

“…Utilizing WCO as a material or energy source is a highly effective approach. It encompasses the production of various products such as bio-lubricants [6][7], bisabolene [8], liquid soap [9], aromatherapy candles [10][11], surfactants [12], plasticizers [13][14], asphalt rejuvenators [15][16], and surfactant [17][18][19] and biofuel feedstock [20][21][22]. WCO (Waste Cooking Oil) has been utilized as a raw material for biodiesel in various locations.…”

Utilizing waste cooking oil for fuel is one of the steps to reduce the uncontrolled environmental impact due to the disposal of waste cooking oil into water bodies and onto the ground. Utilization as fuel will contribute to achieving net zero emissions and reducing global warming as the primary target. With increasing attention to the environment, the extent to which the process of making waste cooking oil impacts the environment has also been widely discussed. Using the Life Cycle Assessment (LCA) methodology as a strong tool to assess the environmental impact, many previous studies have carried out the environmental impact concerning waste cooking oil utilization for biodiesel. This paper reviews previous research from around the world in the 2008-2023 period related to the environmental impact assessment of using LCA in manufacturing waste cooking oil for biodiesel. The review results are divided into scope and technology used, manufacturing raw materials, research locations, functional units, system boundaries (cradle to grave, gate to gate, and gate to grave), software used, midpoint impact assessment, impact assessment method, and impact category.

“…The circular economy concept aims to keep raw materials in a closed circle. Several studies related to the collection of WCO to be used as raw material for other products have been conducted, for example: WCO as a raw material for biodiesel [24,41], soap [42,43], and others. However, research on WCO collection activities and costs associated with the WCO value chain is still extremely limited.…”

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.
