Novel Alginate-, Cellulose- and Starch-Based Membrane Materials for the Separation of Synthetic Dyes and Metal Ions from Aqueous Solutions and Suspensions—A Review

mycolabadmin

This review examines new types of environmentally-friendly membranes made from natural plant materials like alginate and cellulose that can effectively remove harmful dyes and heavy metals from polluted water. These sustainable membranes can reject over 95% of contaminants while producing minimal waste, offering a greener alternative to traditional synthetic membrane technology. The materials are biodegradable and can be reused multiple times, making them economically and environmentally advantageous for water treatment applications.

Effects of Incorporating Ionic Crosslinking on 3D Printing of Biomass–Fungi Composite Materials

mycolabadmin

Researchers developed an improved method for 3D printing with fungal composite materials made from agricultural waste and mushroom mycelium. By adding sodium alginate (a seaweed-derived thickener) and treating the printed objects with a calcium salt solution, they significantly improved the structural integrity and precision of the printed parts. This technique addresses a major challenge in the field where printed objects would shrink and warp after printing, making it possible to create complex shapes from sustainable, biodegradable materials.

Sodium Alginate Modifications: A Critical Review of Current Strategies and Emerging Applications

mycolabadmin

Sodium alginate is a natural substance from seaweed that is safe to eat and widely used in foods, medicines, and environmental cleanup. Scientists have developed various ways to modify sodium alginate to make it stronger, more stable, and better at specific jobs like delivering medicines or creating edible packaging. This review explains both the gentle, food-safe ways to modify alginate for food products and stronger chemical methods used for medical and environmental applications. The modifications allow alginate to work better in areas like wound healing, removing pollutants from water, and protecting food freshness.
