Abstract
A circular economy (CE) is considered capable of being a solution to reduce the use of natural resources and reduce waste without harm. A circular economy system uses products and materials at maximum value and function. Various strategies were developed for this purpose. However, these efforts often require additional energy and materials to create more valuable products. Does the increase in value-creation mean more than the energy consumption and materials to make it happen? This study conducted a study of efforts to increase wood branch waste, which is usually only used for firewood, which is processed into hanger products with an upcycle strategy. This study uses the eco-efficiency method to determine the increase in value in the economic aspect compared to the environmental impact it causes. The cost of environmental impact is calculated using a life cycle assessment with Simapro software. The findings from this study are that upcycle efforts can increase product eco-efficiency. The eco-efficiency index (EEI) of hanger products is 4.512 and the EEI of firewood is 3.816.
