Abstract
This review analyses the main challenges of the process of food waste composting and
examines the crucial aspects related to the quality of the produced compost. Although
recent advances have been made in crucial aspects of the process, such composting
microbiology, improvements are needed in process monitoring. Therefore, specific problems
related to food waste composting, such as the presence of impurities, are thoroughly
analysed in this study. In addition, environmental impacts related to food waste composting,
such as emissions of greenhouse gases and odours, are discussed. Finally, the use
of food waste compost in soil bioremediation is discussed in detail.
