Abstract

Food waste management is an important environmental problem in many developing countries, including Indonesia. Recycling food waste in Indonesia is traditionally done for making compost, landfilling, and animal feed. Therefore, this paper aims to conduct a detailed literature review regarding food waste management and valorization options in Indonesia. The amount of food waste in Indonesia is quite high and needs to be recycled to encourage a circular economy. Some valorization methods are animal feed processing, anaerobic digestion, pyrolysis, hydrothermal carbonization, fermentation, and incineration. The Global Warning Potential (GWP) of anaerobic digestion (AD) for food waste processing is lower than composting or landfilling. An integrated biorefinery approach (HTC, fermentation, and AD) in the FW valorization process leads to a circular economy. The biorefinery process reduces carbon due to reduced waste and replaces bio-based products with fossil-based products. Therefore, using biorefineries may have the greatest climate impact in achieving net zero emissions and carbon emissions. FW recycling is one way to contribute to the circular economy and is a sustainable approach to reducing FW waste.
