Rambutan peel: An unconventional source of lignin and its potential applications in polymer science

This study aimed to evaluate the properties of soda lignin obtained from an unconventional and abundant waste - rambutan peel since has been shown as most promising natural organic feedstock alternative petroleum for polymer science. FTIR analysis pH measurements have confirmed acidic form lignin, which solubility in a wide range polarities so many solvents, making its insertion easy on polymeric matrices. While ability absorb UV-light was higher than commercial tested reference, morphology size distribution at microscopic level were less regular that. When added starch-based film, decreases affinity water, improving barrier properties, well increasing thermal resistance. Microorganisms could be developed easily films containing this kind lignin. material, still underreported technological applications, points towards promisor component or additive
