Poly(vinyl chloride) and chicken feather wastes considered as the dangerous wastes. This study aimedto characterize the prepared composite from poly(vinyl chloride) hydrochar and keratin hydrolyzatefrom chicken feather to get possibility the usage of this composite as soil amendment. The poly(vinylchloride) hydrochar-keratin hydrolyzate composites (HKHC) had been produced with the hydrothermalcarbonization process. The composites were made from different composition of poly(vinylchloride):chicken feather (5:95% (HKHC5), 10:90% (HKHC10) and 15:85% (HKHC15)). Thehydrothermal carbonization process would break and fracture the CHCl bond of poly(vinyl chloride).Moreover, this process would also hydrolyze keratin from chicken feather into small protein. Thecomposite structure was formed from aromatic carbon and amino acids aggregate along with otherorganic substances. The solid composites and liquid residues formed in this process. The compositeswere characterized by FTIR, XRD and TEM and the composite of char-Fe3O4 was characterized bySEM. Meanwhile, the liquid residues were analyzed for its organochlorine by GC-MS and amino acidcontents by HPLC. The results showed that all products have similar properties but the composite withratio 5:95% (HKHC5) had the highest aromatic structure, paramagnetic (Fe3O4) crystallinity and aminoacid contents.
