The chemical speciation of elements including carbon, phosphorus, sulfur and heavy metals determine the environmental behaviors, reactivity, and resource recycling of organic solid waste. Synchrotron radiation-based spectroscopic techniques could characterize the speciation, binding sites, and micro-structure of these elements in organic solid waste in situ at the molecular level and micron/nano scale, which can provide direct evidence for elucidating the behaviors and reaction mechanisms of organic solid waste in the environment. In this paper, the application of synchrotron radiation-based techniques including X-ray absorbance spectroscopy and micro-X-ray fluorescence spectroscopy in pollution control and utilization of organic solid waste research was reviewed. The application challenges and perspectives of these techniques in this field were also discussed. It was expected that this review could provide a comprehensive and effective technical support for the research of the recycling of organic solid waste and the relevant pollution control.
