Description
Summary:Objective: This research aimed to analyze the giant salvina (Salvinia molesta D.Mitch) and water lettuce (Pistia stratiotes L.) potential, collected in the eutrophic environment for biodiesel production.   Theoretical framework: Macrophytes can cause environmental and economic damage in eutrophic environments due to excessive growth, being necessary for removal. In this sense, the destination of this biomass can be challenging.   Method: The moisture and lipid content of the macrophytes was evaluated and the yield of biodiesel produced via in situ transesterification by methyl and ethyl route for dry biomass was compared.   Results and conclusion: S. molesta showed the highest moisture content, with both macrophytes showing a significant difference (p < 0.05) between them and between the analyzed parts. P. stratiotes showed a lipid content significantly higher (p < 0.05). The yield of the biodiesel produced via in situ transesterification, by the ethylic route was higher (p < 0.05) for both biomasses, with P. stratiotes obtaining the best yield and S. molesta presenting the best use for the determined lipid content.   Implications of the research: P. stratiotes presented the best results for the production of biodiesel in the analyzed parameters, being a possible destination for this type of biomass.   Originality/value: The disposal of macrophytes from eutrophication means for biodiesel production is a new eco-friendly alternative for macrophyte infestations. As macrófitas podem causar danos ambientais e econômicos em meio eutrofizados devido ao crescimento excessivo, sendo necessário sua remoção. Neste sentido, a destinação desta biomassa pode ser desafiadora. Com base neste contexto, esta pesquisa objetivou analisar o potencial da salvina gigante (Salvinia molesta D.Mitch.) e alface d'água (Pistia stratiotes L.) coletadas em ambiente eutrofizado para a produção de biodiesel. Deste modo, avaliou-se o teor de umidade e lipídios das macrófitas e comparou-se o rendimento do processo de produção de biodiesel via transesterificação in situ por rotas metílica e etílica para as biomassas secas. A S. molesta apresentou os maiores teores de umidade, com ambas macrófitas apresentando diferença significativa (p < 0,05) entre si e entre as partes analisadas. A P. stratiotes apresentou um teor lipídico significativamente superior (p < 0,05). O rendimento do biodiesel produzido via transesterificação in situ por rota etílica foi superior (p < 0,05) para ambas biomassa
