Potential production of struvite from the anaerobic digestion of food waste: Analysis in one-phase and two-phase configurations. Water Science and Technology, 84(4), 1048–1058. https://doi.org/10.2166/WST.2021.29902731223https://repositorio.usc.edu.co/handle/20.500.12421/7509Anaerobic digestion (AD) of food waste (FW) has been gaining more interest as it has potential for the production of organic amendments with high struvite content, which is a nutrient of great interest in sustainable agriculture. The effect of AD of FW in one- and two-phase configurations on CH4 production and the potential for struvite formation using digestate was investigated. The two-phase was more efficient as its organic loading rate is 18% higher than that of one-phase configuration. Also, the two-phase yielded a higher CH4 content in biogas (>60%) and a higher organic matter transformation in each of the AD stages (>20%). The digestate complied with the regulatory requirements for the use of organic amendments, thereby being deemed as a Type-B material with a struvite precipitation potential, exceeding 80%, as opposed to the digestate from one-phase configuration, which may represent a revenue of up to US$ 26,505/yr.enBiogasDigestatesHydrolysisMass balanceMethaneArticle
