Enhancement of the Amazonian Açaí Waste Fibers through Variations of Alkali Pretreatment Parameters.

The açaí fruit depulping produces large amounts of long lignocellulosic fiber bundles that are disposed in the environment. Chemical pretreatments may improve açaí fibers favoring their usage in advanced materials. This work aimed to define optimal alkali reaction parameters to improve the properties of açaí fibers.
