Exploratory, observational and experimental, Literature Review, amongst other methods, were used within a Qualitative and Quantitative Methodology by Design through practice. The research material was documented through an open-source FabLab platform and shared with a community of researchers and future designers who want to design innovative and environmentally friendly materials to replace synthetic plastics. Fifteen different bio-based materials resulted from this experiment, applicable for varied applications. Results show that different fillers added to sodium alginate and glycerine present ample opportunities for sustainable bio-ceramics, bio-composites and bio-plastics.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo Este estudo explora a fabricação de bioplásticos à base de polímero de alginato com adição de glicerina como plastificante, criando flexibilidade. Resíduos orgânicos foram usados como enchimento e reduzir o encolhimento. Foram utilizados métodos Qualitativos e Quantitativos para Design através da prática, tais como: Exploração, Observação e Experimentação, e Revisão de Literatura, entre outros. O material de pesquisa foi documentado por meio de uma plataforma FabLab de código aberto e compartilhado com uma comunidade de pesquisadores e futuros designers que desejam projetar materiais inovadores e ecológicos capazes de substituir os plásticos sintéticos. Resultaram desta experiência quinze materiais de base biológica, aplicáveis &#8203;&#8203;a diversas funções. Os resultados mostram que diferentes enchimentos adicionadas ao alginato de sódio e glicerina apresentam amplas oportunidades para biocerâmicas, biocompósitos e bioplásticos sustentáveis.]]></p></abstract>
