SUMMARY:

Forensic Papilloscopy stands out in Forensic Sciences for presenting the simplest and fastest methods for human identification, compared to Forensic Odontology and Forensic Biology. Forensic Papilloscopy includes several techniques used to identify fingerprint and other ridge impressions, with the powders application being the most widely used due to its simplicity, versatility and portability. However, the vast majority of the products used are toxic and carcinogenic, such as carbon black, harming the health of professionals due to its extensive use, in addition to high commercial values. In this context, the present work proposes the development of alternative developers from renewable biomass - biochar from coffee solid waste (BBC) and bioactive curcuminoids from Turmeric (BBC-CB) - obtained by technological and sustainable processes. BBC, a porous material with non-toxic characteristics, was produced by carbonization of coffee solid waste. For this purpose, coffee solid waste, renewable raw material, was previously characterized by Thermogravimetric Analysis (TG/DTG) and Fourier Transform Infrared Spectroscopy (FTIR). Bioactive curcuminoids were obtained from Turmeric (Curcuma longa) by solid-liquid extraction processes applying the principles of Green Chemistry. The extracted curcuminoids were characterized by Spectroscopy in the Ultraviolet-Visible region (UV-Vis), Spectroscopy in the Infrared region with Fourier Transform (FTIR) and Direct irradiation of UV light. The BBC and BBC-CB were characterized by FTIR, Raman Spectroscopy, X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and the Brunauer, Emmett and Teller method (BET). Finally, preliminary tests were carried out with BBC and BBC-CB to reveal fingerprints and other ridge impressions, demonstrating the potential of these materials as efficient and sustainable developers.
