Abstract:
Polylactic acid (PLA) is a thermoplastic polymer produced from lactic acid that has been chiefly utilized in biodegradable material and as a composite matrix material. PLA is a prominent biomaterial that is widely used to replace traditional petrochemical-based polymers in various applications owing environmental concerns. Green composites have gained greater attention as ecological consciousness has grown since they have the potential to be more appealing than conventional petroleum-based composites, which are toxic and nonbiodegradable. PLA-based composites with natural fiber have been exten

Abstract:
Fully biodegradable flax/polylactic acid (PLA) thermoplastic composites were fabricated by using random (nonwoven mat) and aligned (unidirectional yarn) flax fiber as reinforcements (39% flax by volume) and Polylactic acid (PLA) as matrix. Results revealed that the aligned flax fibers have a greater reinforcing effect due to the uniform distribution of load axially along the fiber length in the composite. The aligned flax/PLA and random flax/PLA showed the tensile strength of (83.0 ± 5.0) and (151.0 ± 7.0) MPa respectively and flexural strength of (130.0 ± 5.0) and (215.0 ± 7.2) MPa respective

In view of the phenomenon that the interfacial adhesion between bamboo fiber（BF）and polylactic acid (PLA) is poor and incompatible. Firstly the BF-g-PLA structure with hydrophobicity is synthesized through grafting lactic acid into bamboo fiber, then plasticizing the composite. Three-element compound plasticizer was prepared by mixing glycerol, tributyl citrate and formamide. The effect of the proportion and addition content of three-element plasticizer on the interfacial compatibility of the composite was investigated.

Uniaxial tensile tests with two different load rates, one and 50 mm/min, were performed. An increase in maximum strength and E-modulus of DuraPulp was observed by increasing the press time, while PLA content decreased the maximum strength and E modulus.

Abstract:
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 during dairy plant disinfection to enhance sustainable livestock production. It explores the use of biosolids as the primary matrix for creating composted compounds and biopolymers for agricultural purpo

Abstract:
Per- and polyfluoroalkyl substances (PFAS) are recalcitrant substances present globally in many landfill wastewater leachates and have potential ecological and human health risks. Conventional treatment technologies have shown limited efficacy for many PFAS due to the stable C–F bonds. Therefore, there is growing interest in applying advanced oxidation processes to decrease the aqueous concentrations in contaminated wastewater and mitigate risks. The goal of this study was to evaluate the photocatalytic performance of treating PFAS in landfill leachate using a novel photocatalyst composite. Tr

Abstract:
This Dredging Operations Environmental Research (DOER) technical note disseminates novel methods to monitor and reduce contaminant mobility and bioavailability in water, sediments, and soils. These method advancements are enabled by additive manufacturing (i.e., three-dimensional [3D] printing) to deploy and retrieve materials that adsorb contaminants that are traditionally applied as unbound powders. Examples of sorbents added as amendments for remediation of contaminated sediments include activated carbon, biochar, biopolymers, zeolite, and sand caps. Figure 1 provides examples of sorbent an

Abstract:
The Army Climate Strategy has identified goals to reduce greenhouse gas (GHG) emissions to reach net-zero Army GHG emissions by 2050. Producing fossil-fuel-based plastics releases GHG emissions and plastic bottles are difficult to dispose, especially in contingency locations. Soldiers prefer hydrating with plastic water bottles, which leads to GHG emissions. This project investigates using bioplastics for water bottles. These bioplastics are produced from natural materials and can break down faster with alternative disposal methods, such as composting. Challenges include finding a material wit
