Polylactic acid (PLA) is the bioplastic with highest market share. However, it mainly produced from first-generation feedstock and there are various inconsistencies in literature terms of its production recycling processes, carbon footprint, prices. The aim this study to compile contrast these aspects investigate second-generation PLA technical, economic, ecological perspectives simultaneously. comprehensive analyses also show chances challenges originating a supply chain specific region. Herein, German Federal State North Rhine-Westphalia (NRW) has been chosen as region interest. In addition highlighting industrial capabilities synergies, quantifies illustrates locations different suitable feedstocks identified potentials can be challenged by obstacles such high demand bioresources, quality, spatial aspects, logistics. Furthermore, substantial price gap between fossil-based plastics discourage investors include on their portfolios. Thus, provides recommendations overcome promote regional value chains bioplastics which may serve prototype for other regions.

Phase Morphology and Mechanical Properties of Super-Tough PLLA/TPE/EMA-GMA Ternary Blends

Polymers, Год журнала: 2024, Номер 16(2), С. 192 - 192

The inherent brittleness of poly(lactic acid) (PLA) limits its use in a wider range applications that require plastic deformation at higher stress levels. To overcome this, series poly(l-lactic (PLLA)/biodegradable thermoplastic polyester elastomer (TPE) blends and their ternary with an ethylene-methyl acrylate-glycidyl methacrylate (EMA-GMA) copolymer as compatibilizer were prepared via melt blending to improve the poor impact strength low ductility PLAs. thermal behavior, crystallinity, miscibility binary analyzed by differential scanning calorimetry (DSC). Tensile tests revealed brittle–ductile transition when PLLA/20TPE blend was compatibilized 8.6 wt. % EMA-GMA, elongation break increased from 10.9% 227%. “super tough” behavior PLLA/30TPE/12.9EMA-GMA incomplete notched 89.2 kJ∙m−2 observed ambient temperature (23 °C). In addition, unnotched PLLA/40TPE samples showed tremendous improvement crack initiation resistance sub-zero test conditions (−40 °C) 178.1 kJ∙m−2. Morphological observation electron microscopy (SEM) indicates EMA-GMA is preferentially located PLLA/TPE interphase, where it partially incorporated into matrix encapsulates TPE. excellent combination good interfacial adhesion, debonding cavitation, subsequent shear yielding worked synergistically phase sea–island co-continuous morphology form interesting super-toughening mechanism.
