Access to safe drinking water has been a long-lasting problem in Bangladesh. To circumvent this problem, scientists from Uppsala University, Sweden, and Dhaka University have demonstrated how green macroalgae species could be used to extract cellulose nanofibers, which could be then transformed into thin paper sheets to purify water. The filter has proven to be very effective in removing harmful virus and bacteria from contaminated water and very affordable. Thus, this paper filter can eventually save the lives of the Bangladeshi people and more, amounting up to over 168 million people.
