Paper filter from local algae could save lives in Bangladesh

The problem of access to safe drinking water in most parts of Bangladesh is a persistent challenge. Now, a team of scientists from Uppsala University, Sweden, and Dhaka University, Bangladesh, shows that a locally growing and previously unexploited green macroalgae species could be used to extract cellulose nanofibers, which can then be formed into paper sheets with tailored pore size that are utilized for point-of-use water treatment.
