Frontiers in Bioengineering and Biotechnology, 2023 Here, we report the marine degradability of polymers with highly ordered structures in natural environmental water using microbial degradation and biochemical oxygen demand (BOD) tests. Three types of elastic fibers (non-porous as-spun, non-porous drawn,

Fabrication of biodegradable nanofibers via melt extrusion of immiscible blends
e-Polymers, 2022 Polylactic acid (PLA) and poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P(3HB-co-4HB)) nanofibers were prepared by melt extrusion of immiscible blends of PLA/polyvinyl alcohol (PVA) and P(3HB-co-4HB)/PVA via in situ formation of microfibrils during the ...

Pretreatment and Anaerobic Co-digestion of Selected PHB and PLA Bioplastics
Frontiers in Environmental Science, 2018 Conventional petroleum-derived plastics are recalcitrant to biodegradation and can be problematic as they accumulate in the environment. In contrast, it may be possible to add novel, biodegradable bioplastics to anaerobic digesters at municipal water ...
