  2. 1. Agro-Waste Derived Additives for Polylactide and Tapioca Starch

    Author : Edwin Azwar; Minna Hakkarainen; Anna Wistrand; Christian Glandfils; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agro-industrial waste; wood flour; rice bran; polylactide; starch; biomass; degradation; SRA - E-vetenskap SeRC ; SRA - E-Science SeRC ;

    Abstract : Development of materials from renewable resources is one of the big challenges facing our world. In this thesis agro-industrial waste derivatives were developed and evaluated as additives for two common renewable polymer matrices, polylactide (PLA) and starch. Two waste products, wood flour (WF) and rice bran (RB) were evaluated in different forms. READ MORE
