Novel green composites based on commercial poly(3-hydroxybutyrate) (PHB) filled with
10 wt % rice husk flour (RHF) were melt-compounded in a mini-mixer unit using triglycidyl
isocyanurate (TGIC) as compatibilizer and dicumyl peroxide (DCP) as initiator. Purified poly(3-
hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) produced by mixed bacterial cultures derived from
fruit pulp waste was then incorporated into the green composite in contents in the 5–50 wt % range.
Films for testing were obtained thereafter by thermo-compression and characterized. Results showed
that the incorporation of up to 20 wt % of biowaste derived PHBV yielded green composite films with
a high contact transparency, relatively low crystallinity, high thermal stability, improved mechanical
ductility, and medium barrier performance to water vapor and aroma. This study puts forth the
potential use of purified biosustainably produced PHBV as a cost-effective additive to develop more
affordable and waste valorized food packaging articles. [-]
