Abstract

The issue related to pig coat has aroused concern in the industrial sphere due to the significant production driven by the increase in pork consumption, which results in a high generation of waste such as hair. This waste is currently destined for landfills, causing environmental impacts. In order to identify and analyze the technological routes applicable to the recycling, reuse, treatment and valorization of pig coats, the present study was conducted. To this end, bibliographic surveys were carried out through searches in the Scopus (Elsevier) and Web of Science (Clarivate) databases, as well as in patent databases such as the National Institute of Industrial Property (INPI) and the World Intellectual Property Organization (WIPO­ PATENTSCOPE). Based on this information, scientific portfolios, bibliometric analyses and the state of the art were elaborated, followed by the construction of a technological portfolio, patentometry and state of the art. These prospections allowed the preparation of the strategic analysis of the technological routes and, finally, the systematic elaboration of the routes applicable to the coat. The bibliometrics allowed to identify the prominence of two universities: Delta State University Abraka of Nigeria and Hunan Microbiology Institute Changsha, of China that had greater generation of knowledge on the subject of research. The participation of two Brazilian universities was identified, namely: the Federal University of Santa Catarina (UFSC) and the Federal University of the Southern Border (UFFS). The mapping of the technological routes identified the main technologies that are being applied in the processing of coat residues, which are: biotechnological processes, hydrolysis, pyrolysis, biofilter and equipment for cleaning residues of the pork coat. The analyzed works presented the following products that are generated through the coat: amino acids, protease, protein, keratin, oligopeptide, civil construction material, mercaptopropionic, bio­oil and absorbent. As for the publication of scientific papers, the lack of knowledge generation on the use of hair at the national level was evidenced, which points to the need for deepening on the subject. As for the technological routes investigated, the most evident was the reuse.
