15. Orange and Passion Fruit Wastes Characterization, Substrate Hydrolysis and Cell Growth of Cupriavidus necator, as Proposal to Converting of Residues in High Value Added Product
Abstract: Brazil is the world’s largest producer of orange and passion fruit, which are destined mainly for industrialization, generating grand volumes of wastes. The solid portion of these residues is a rich source of pectin - composed mainly of galacturonic acid and neutral sugars, which through the hydrolysis process can be used in biological conversion

20. Characterization of mineral wools obtained from ornamental rock wastes
Abstract The study aimed to characterize the mineral wools obtained from wastes of the cutting step of marble and granite, in order to evaluate the possibility of their use on an industrial scale. Mixtures of marble and/or granite wastes were prepared in order to reach the chemical composition of rock and glass wools. The batches were melted in an electric a

24. Partial-hydrothermal hydrolysis is an effective way to recover bioactives from turmeric wastes
Abstract Partial-hydrothermal hydrolysis using pressurized hot water was applied in waste turmeric, derived from extraction processes that employed supercritical and pressurized fluids, as a sustainable alternative for the recovery of bioactive constituents from this material. The reaction products consisted of a liquid extract of fermentable sugars and a so
