Fabrication of Biodegradable Materials Using Sodium Alginate and Tamarind Seed Powder
AI summary Read the abstract
Researchers developed biodegradable biofilms for textile applications by combining sodium alginate with tamarind seed powder and natural flower extracts — hibiscus for pH sensitivity, marigold for UV protection, and rose for antioxidant activity — creating sustainable fabric alternatives that avoid microplastic pollution associated with synthetic fabrics persisting in landfills for centuries.
The fashion industry is a major polluter due to synthetic fabrics that persist in landfills for centuries. This study explored sodium alginate, a biodegradable polymer from seaweed, combined with tamarind seed powder (TSP), to create sustainable biofilms for textiles. By incorporating natural flower extracts—Hibiscus for pH sensitivity, Marigold for UV protection, and Rose for antioxidant activity—the films have value added from the eco-friendly colouration and functional properties. These biofilms not only degrade safely without leaving dangers on the use of microplastics but also merge sustainability with aesthetics, offering a step towards responsible innovation.

Mechanical, structural, and biodegradability properties of bioplastics from tamarind seed starch
AI summary Read the abstract
Researchers synthesised bioplastics from tamarind seed starch and characterised their mechanical, structural, and biodegradability properties as a sustainable alternative to synthetic plastics. The study demonstrated that tamarind starch-based bioplastics exhibit adequate mechanical performance and substantially faster biodegradation compared to conventional plastics, reducing the risk of microplastic accumulation in the environment.
Multifunctional Alginate Composite Fibers Based on Pre-Crosslinked Spinning Solutions
AI summary Read the abstract
Scientists have created a new type of fiber made from seaweed extract (alginate) and titanium dioxide nanoparticles that's strong, biodegradable, and could replace plastic-based textiles—offering a potential way to cut down on microplastic pollution. As a bonus, these fibers can break down formaldehyde (a chemical found in some fabrics and furniture that can irritate lungs and eyes) and resist catching fire, making them promising for healthier, safer textiles in homes.
Development of Biodegradable Packaging Material from Tamarind (Tamarindus indica) Kernel Powder
AI summary Read the abstract
Scientists created a plastic alternative using tamarind seed powder, corn flour, and glycerol that fully breaks down in soil within just 15 days—unlike synthetic plastics that can persist for centuries and shed microplastics into our food and water. This matters because most people (82% in the study's survey) already want eco-friendly packaging, and this tamarind-based film is both sturdy enough for practical use and made from a cheap agricultural byproduct, making it a realistic step toward reducing plastic pollution and our exposure to plastic particles in everyday products.
Innovations and Challenges in Biodegradable Textile Materials: A Review of PLA, PHA and Natural Fibers in Sustainable Fashion
AI summary Read the abstract
This review examines biodegradable textile alternatives, including polylactic acid, polyhydroxyalkanoates, and natural fibers like hemp and bamboo, that could reduce microplastic pollution from the fashion industry. While these materials offer environmental advantages, challenges remain around high production costs, performance limitations, and lack of recycling infrastructure. The authors highlight innovations in biopolymer blends and eco-friendly dyeing that could accelerate adoption of textiles that do not shed persistent microplastic fibers.
Sustainable encapsulation of lipophilic fragrances using biodegradable sodium alginate for cosmetic applications
AI summary Read the abstract
Researchers developed a sustainable encapsulation method for lipophilic fragrances using biodegradable sodium alginate, replacing conventional non-biodegradable microplastic-classified shell materials used in cosmetics, food, and detergent industries. The approach offers a viable eco-friendly alternative that reduces microplastic pollution from fragrance encapsulation applications.
