Scientists have developed a new technique that filters out microplastics from drinking water — and its ingredients are all plant-based.
To test the system, the team of forestry, chemistry, and biological engineering researchers gave groups of mice either drinking water purified with the bioCap or untreated water.
"There are [microfibers] from clothing, microbeads from cleansers and soaps, and foams and pellets from utensils, containers, and packaging," Dr. Orlando Rojas, the scientific director of UBC's BioProducts Institute, said in the school's press release. "By taking advantage of the different molecular interactions around tannic acids, our bioCap solution was able to remove virtually all of these different microplastic types.
Whether it needs to be scaled up for industrial use — or down for home use — Rojas said that the bioCap is an ideal solution because it's made of organic materials and does not lead to "further pollution" like plastic filters do. It's an excellent proposal for a deceptively simple solution — and hopefully, people in power concerned about the
