Growing concerns about ocean contamination from fossil fuel based polymers have created a demand for biodegradable alternatives, particularly for packaging applications. Thermoplastic starch (TPS) is a promising, eco-friendly biopolymer but has poor mechanical properties and high hydrophilicity. To address these issues, this article explores modifying starches through reactive extrusion and ble...

Crown rot is a severe postharvest disease affecting tropical and subtropical fruits like mango, avocado, papaya, and banana. It is caused by fungal pathogens that penetrate the fruit, reducing its pulp and leading to premature ripening. Systemic fungicides have been used to control these fungi, typically applied to seeds, leaves, or fruits to prevent disease spread. However, traditional fungici...

In the Cesar Department in Colombia, sustainable agriculture faces critical challenges despite its thriving livestock sector. Extensive cattle ranching and poor soil management worsen soil conditions. Additionally, significant environmental concerns arise from the substantial discharge of wastewater in the dairy processing industry. This study aims to valorize biosolids derived from wastewater ...

The 39th International Conference of the Polymer Processing Society (PPS-39) was hosted by Uni versidad de los Andes and ICIPC and attended by nearly 435 participants from 41 countries. Besides traditional symposia about polymer processing, the PPS-39 program included four special symposia on Biopolymers, Biocomposites, and Bioprocessings; Circular Economy of Polymers; Degradation; and Biodegra...
