Optimizing bioremediation techniques for soil decontamination in a linguistic intuitionistic fuzzy framework

mycolabadmin

This research develops mathematical tools to help experts choose the best method for cleaning contaminated soil using living organisms. The study presents new fuzzy logic operators that can handle both numerical and linguistic information, making decisions more understandable to humans. When applied to a contaminated industrial site, the method identified bioaugmentation (adding beneficial microorganisms) as the most effective cleanup approach among four options tested.

Effect of nano-TiO2 size and utilization ratio on the performance of photocatalytic concretes; self-cleaning, fresh, and hardened state properties

mycolabadmin

Scientists developed a new type of concrete that can clean itself by breaking down pollutants in water using nano-sized titanium dioxide particles and sunlight. The study tested different sizes and amounts of these nanoparticles to find the best combination for removing textile dyes from wastewater. While the larger nanoparticles worked better for photocatalytic cleaning, the smaller ones made the concrete stronger, suggesting a trade-off between cleaning ability and structural durability.

Experimental Assessment of Multiple Properties of Mycelium-Based Composites with Sewage Sludge and Bagasse

mycolabadmin

Researchers created building materials using mushroom mycelium grown on sewage sludge and bagasse, eliminating waste while producing lightweight, eco-friendly composites. These materials showed excellent strength and thermal properties comparable to conventional highway backfill materials, but with significantly lower environmental impact. The study demonstrates that mycelium can effectively bind sewage sludge into useful construction materials, offering a practical solution for waste management and sustainable building.
