Aproveitamento da Pele de Tilápia (Oreochromis niloticus) (Linnaeus, 1758) Curtida Artesanalmente: promovendo o desenvolvimento local e a geração de renda com o artesanato sustentáve

Abstract

The search for greater productivity has increasingly densified production systems, placing more and more fish in smaller volumes of water. Waste generation has also increased, because in order for the fish to reach the consumer's table in the form of fillets, much of the fish was probably discarded incorrectly, causing significant environmental damage in the producing regions, strongly associated with the putrescibility of these organic residues. In this sense, it was necessary to research and evaluate the possibility of reducing the waste of fish waste, in this case, skins. In this context, the objective of the study was to propose the use of hand-tanned tilapia skin (Oreochromis niloticus) (Linnaeus, 1758) with a view to promoting local development and generating income through sustainable crafts. To this end, the study was conducted with elementary school students, a teaching modality for young people and adults, and a pedagogical model based on the pedagogy of alternation. The first stage of the study consisted of meetings with the management, teachers and students of ECFR. The second stage of the study was carried out through training sessions focused on the theme <Artisanal tanning of fish skin=, given in the form of lectures. And, in the third stage of the work, workshops were held with the students to create sustainable crafts in the form of jewelry. After analysis, the prototypes developed resulted in a high-quality and durable product, useful for obtaining handmade pieces. The students realized that they can produce and add value to waste that is thrown away by making earrings, necklaces and bracelets. Thus, the possibility of generating income for the young people was accompanied by an insight into the social, economic and environmental aspects related to environmental conservation. The artisanal tanning of fish skin is an alternative to reduce the negative impact caused by the disposal of this type of material in the environment. The leather obtained is a high-quality and durable by-product, which is suitable for creating various handmade pieces, such as jewelry. This type of use contributes assertively to the generation of income and equality of the communities involved, strengthening the local economy
