Recently the perception of digestate gradually shifted from waste to products to realize the concept of circular economy and maximize the benefits of digestate valorization. Land application of digestate should be the simplest way for digestate valorization, while legislation restriction and environmental issues emphasize the necessity of novel valorization methods. This review then outlined the current methods for solid/liquid digestate valorization, nutrient recovery, microalgae cultivation, and integration with biological and thermochemical processes. The novel valorization routes proposed were summarized, with their challenges and prospects being discussed. Integrating anaerobic digestion with thermochemical methods such as hydrothermal carbonization should be a promising strategy due to the potential market value of hydrochar/biochar-derived products. |
