Living filtering materials
Living filtering materials use living organisms or biological molecules, not inert media, as the active filtration or treatment element: California's BioFiltro fills wood-chip beds with living red earthworms and microbes to filter dairy and municipal wastewater, and India's Banka BioLoo digests human waste on-site with an anaerobic bacterial consortium in sewer-free bio-toilets. Scotland's James Hutton Institute is field-trialling ElecTrickle, a bioelectrochemical wastewater process built on a nourished, electroactive biofilm, and Denmark's Aquaporin embeds the aquaporin water-channel protein found in living cell membranes into biomimetic reverse-osmosis membranes, cutting energy use at Singapore's Kranji NEWater Factory by up to 20%.
