Speeding it up: dual effects of biostimulants and iron on the biodegradation of poly(lactic acid) at mesophilic conditions
Published on February 24, 2024
Biodegradation of poly(lactic acid) (PLA) in compost and environments enriched with iron, gelatin, skim milk, and ethyl lactate under moderate temperature conditions. Introducing iron and gelatin significantly accelerates PLA biodegradation. -
Accelerating Biodegradation: Enhancing Poly(lactic acid) Breakdown at Mesophilic Environmental Conditions with Biostimulants
Published on February 24, 2024
Including gelatin, skim milk, and ethyl lactate in the compost helps improve the protease activity and stimulates the activity of lactate utilizing microorganisms, thus improving the biodegradation rate of PLA at mesophilic temperatures. -
Unlocking the secrets of high-water barrier stereocomplex polylactide blend extrusion films
Published on February 24, 2024
Stereocomplex polylactide (sc-PLA) films were produced without using a masterbatch, including varieties with PLLA/PDLA ratios of 85/15, 70/30, 50/50, and 30/70. Blended and annealed films show a reduced moisture barrier by a factor of 2.5 to 6. -
Hydrolytic Degradation of Poly(lactic acid): Unraveling Correlations between Temperature and the Three Phase Structures
Published on September 23, 2023
This work investigates the hydrolysis kinetics of PLA films as affected by the degree of crystallinity and temperatures by considering the three-phase model structures (i.e., mobile amorphous, rigid amorphous, and crystalline). -
PPWR2: Optimizing Packaging Systems' Safety for Reuse and Recycling in Compliance with the New Packaging and Packaging Waste Regulation
Published on September 11, 2023
The new PPWR is a cornerstone of the European Commission's Circular Economy Action Plan. All packaging in the EU will need to adapt to these regulations starting in 2025. Join us for the 2nd Symposium on Packaging Materials Supply Chain Safety. -
