Water filtration using softwood membranes provides a nature-based solution for nanoplastic removal

AI summary · Read the abstract

Researchers tested native softwood and hardwood membranes as low-cost, pressure-driven filters for nanoplastic removal from freshwater, finding that spruce membranes reduced nanoplastic concentrations by approximately 90% in a single filtration cycle — far outperforming poplar — with performance improving further under increased membrane thickness and repeated cycling.

Removal of Plastics from Micron Size to Nanoscale Using Wood Filter

AI summary · Read the abstract

This study demonstrated that porous wood filters can effectively remove both microplastics and nanoplastics from water, offering a low-cost, biodegradable alternative to conventional filtration materials.

Rapid removal of small particle-sized microplastics utilizing superhydrophobic wood membranes

AI summary · Read the abstract

Researchers developed a superhydrophobic wood membrane that achieves 99.6% removal efficiency for microplastics smaller than 10 micrometers. The membrane, created by treating wood with methyltrichlorosilane, maintained its performance across varying water flow rates and demonstrated excellent reusability and environmental friendliness. The study offers a practical and sustainable filtration solution for removing the smallest and most difficult-to-capture microplastics from water.

Functionalized natural fibre composite filter for the removal of microplastics and heavy metal ions from water

AI summary · Read the abstract

Researchers developed a biodegradable water filter from chitosan-functionalized coir fiber and pith that effectively removed microplastics alongside heavy metals (lead, cadmium, chromium) and organic carbon from water. This low-cost, natural-material filtration approach offers a promising point-of-use solution for microplastic removal from drinking water, particularly relevant for communities lacking advanced water treatment infrastructure.
