Abstrakt: The amount of waste cooking oil (WCO) continues to increase every year in line with population growth and the culinary industry. Most of the waste cooking oil is disposed of in landfills. Waste cooking oil that is thrown into the environment can contaminate water and soil. Based on earlier research, waste cooking oil can be created as other valuable products such as biodiesel, floor cleaners, and soap. However, earlier research is still limited to testing the quality of the product resulted from the waste of cooking oil and its eco-efficiency level has not been studied. This research intends to recycle used cooking oil into liquid dish soap followed by environmental impact analysis and eco-efficiency. The environmental impact analysis is calculated using the Life Cycle Assessment method. This research includes the identification of environmental costs from the process of producing soap based on coffee grounds as an adsorbent. The system that will be carried out is the gate to gate from the process of filtration, adsorption, and saponification. The results will be compared with the same recycling process as the earlier research but using a different adsorbent, namely coffee grounds adsorbent. The results of this study found that coffee grounds are more recommended as an adsorbent for WCO recycling into dishwashing liquid soap because it has a lower eco-cost € 0.065 compared to € 0.0730 resulted from banana peels and a better eco-efficiency indicator in the criteria of Index Eco-efficiency, Value Ration of Eco-Cost and ratio of eco-efficiency.
