SUMMARY:

Global fishery and aquaculture production increased by 41% between 2000 and 2020, reaching 178 million tons. Of this total, 13% corresponds to mollusk consumption. A large volume of waste is generated during mollusk processing, consisting mainly of shells, which account for approximately 65–90% of the live weight, depending on the species. Considering only bivalve mollusks, over 10 million tons of shells are discarded annually, typically in open fields or landfills. Improper disposal of shell waste alters soil, water, and marine ecosystems. In mangrove areas, shell dumping contributes to the siltation of water bodies and causes ecological imbalance. Furthermore, disposal in vacant lots can promote the proliferation of animals and insects that transmit diseases and pose safety risks to beachgoers due to the sharp and cutting nature of the waste. The general objective of this research is to propose a technological route for the management of shellfish waste generated in the municipality of Igarassu, Pernambuco, aiming at its recycling and environmentally sound disposal. The research is organized into three chapters, each structured as a scientific article derived from the study phases. The methodology was divided into three stages: (i) an analysis of shellfish harvesting in Mangue Seco Beach, Igarassu–PE; (ii) a bibliometric study of available technologies for mollusk shell recycling; and (iii) the mapping and proposal of a new technological route for shellfish waste management. Based on the results presented, this research is expected to provide valuable data to support decision-making regarding the management of shellfish waste in Igarassu. Furthermore, it is hoped that this study will promote the inclusion of mollusk shell waste as a source of income and employment for the local community, improving working conditions for shellfish gatherers and positively impacting their families and the broader community.
