SUSTAINABLEUSE OF Anomalocardia flexuosa SHELLS: EFFICACY IN SEED GERMINATION AND EARLY SEEDLING DEVELOPMENT
Sustainable agriculture, agricultural substrate, germination, seedling development, shell waste, sustainability
The growing demand for food and reliance on synthetic fertilizers in agriculture pose environmental and economic challenges. Among these challenges are soil degradation, greenhouse gas emissions, and pollution of aquatic ecosystems. In this context, the sustainable use of agro-industrial waste, such as mollusk shells, emerges as a promising alternative to minimize environmental impacts and reduce dependence on chemical inputs. Thus, this research investigates the potential of utilizing the shells of this mollusk species, widely harvested in Brazil, as a substrate for seed germination and early seedling development. The study evaluates the technique of using shell powder as a component of agricultural substrates, identifying its benefits and challenges. The results indicate that A. flexuosa shells, primarily composed of calcium carbonate, have the potential to promote rapid and uniform germination, essential characteristics for seedling production. This study provides insights for the development of strategies that incorporate seafood industry waste into sustainable agricultural practices, promoting a more ecological and efficient agriculture.
SOCIAL IMPACT OF THE THESIS: The ongoing thesis addresses various dimensions, particularly concerning environmental sustainability and the local economy. Initially, it explores the reuse of Anomalocardia flexuosa shells, a widely discarded waste in coastal regions. The research suggests using these shells as an agricultural input, promoting a more sustainable approach to waste management. This reuse can directly help reduce pollution and waste accumulation, benefiting coastal communities that face challenges related to the improper disposal of these materials. Economically, based on the results, this could be a viable alternative for small farmers and local producers, who can incorporate shell powder into their agricultural practices, reducing their reliance on expensive chemical inputs while promoting the use of abundant and accessible natural resources. This could contribute to the creation of more sustainable production chains, involving the collection and processing of shells, which could generate jobs and income for coastal communities. By transforming waste into a resource, this approach promotes a circular economy, benefiting both the agricultural sector and artisanal fisheries.
