Value of the data •The dataset can be used to monitor changes in the properties of hydroxyapatite derived biomaterials at the microscale •Researchers working on biomaterials and biowaste valorization can benefit hugely from the data •The FTIR data provided in this article provides an indirect evaluation of the synthesized hydroxyapatite, showing the most characteristic chemical groups in the FTIR spectrum of synthesized HAp such as PO43−, OH-, CO32−. •Data obtained in this study would be useful for future investigation on the industrial applicability of biowastes derived hydroxyapatite
