Bio-geotextiles based acrylonitrile and their evaluation on radish plants (Raphanus sativus)
AI summary Read the abstract
Researchers developed two novel bio-geotextiles from acrylonitrile-based terpolymers incorporating starch and chitosan respectively, characterizing their mechanical properties and evaluating their effects on radish plant growth. The bio-geotextiles demonstrated tensile strengths of 28.5-74.7 MPa and were assessed for agronomic suitability as biodegradable soil reinforcement materials.
In this study, two innovative biopolymers (BioP) were investigated for bio-geotextile (BioG) fabrication: an acrylonitrile-2-hidroxyethyl methacrylate-starch terpolymer (ST-AN), and a composite of acrylonitrile-vinyl acetate-chitosan terpolymer (CS-AN) blended with acrylonitrile-methyl acrylate (AN-MA) copolymer. Using wet-spinning technique, bio-fiber (BioF) were produced, characterized and utilized in to construct BioG. BioF based on ST-AN and CS-AN exhibited linear densities of 10.7 and 19.8 denier, bulk densities of 1.21 and 1.16 g/cm³, tensile strengths of 74.7 MPa and 28.5 MPa, elongation of 10.7% and 11.2%, and moisture retention capacities of 88% and 65%, respectively. The BioG made with ST-AN improved soil moisture retention by up to 130%. Radish plants biometric measurement in pots with BioG revealed improvements in growth parameters: leaf length increased by 87%, leaf width by 45%, and stem thickness by 142% compared to controls. These findings highlight the potential of bio-based materials to advance sustainable engineering through innovative strategies in synthesis, processing, and application, offering a viable alternative for the partial or complete replacement of plastics associated with microplastic generation and persistent environmental pollution.

Bio-based Terpolymers: Synthesis, Characterization, Wet-Spinning, and Evaluation as Geotextile
AI summary Read the abstract
Researchers synthesized new biodegradable terpolymers combining starch, chitosan, and synthetic monomers, then spun them into fibers and wove them into geotextiles that improved plant growth and soil moisture retention. These bio-based materials offer a potential path to replacing conventional plastics in agricultural applications, reducing the microplastic pollution that standard geotextiles generate as they degrade.
Biochar as a Soil Amendment for Mulch-Derived Microplastics-Contaminated Soils: Impacts on Raphanus sativus L. Growth Under Greenhouse Conditions
AI summary Read the abstract
A greenhouse pot experiment tested whether adding biochar to microplastic-contaminated soil could improve crop growth, finding that a 3% biochar addition produced the best radish yields — significantly higher fresh weight — in soil spiked with 0.5% microplastics by weight. Biochar also improved multiple soil health indicators including pH, water retention, organic carbon, and nitrogen availability. The results suggest biochar soil amendment is a promising remediation strategy for agricultural land contaminated by plastic mulch film debris, though more testing across different plastic and crop types is needed.
Development of bio-based, biodegradable geotextiles for the revegetation of stabilized landslide-prone areas
AI summary Read the abstract
Researchers developed bio-based, biodegradable geotextile materials from natural fibers for revegetating landslide-prone slopes as an alternative to synthetic plastic geotextiles. The natural fiber materials supported plant growth and degraded over time without leaving persistent plastic in the soil. Replacing synthetic geotextiles with biodegradable alternatives could reduce microplastic contamination of soil and nearby waterways.
