Home-Compostable Water Filters from Food Waste

Traditional water filters consist of activated carbon housed in plastic cartridges, both of which are generally derived from non-renewable coal and petroleum, 100 millions of which end up in landfills every year. Strøm is a collection of carbon water filters made completely without fossil fuels, by turning food waste into carbon-rich biochar and combining it with natural resins, so it can be shaped like a thermoplastic. The resulting composite acts as both filter and vessel at the same time and will decompose in soil over the course of a single month.
