The Nutree is a device that cleans wastewater using three different complementary technologies. Engineered wetlands, aquaponics, and microbial fuel cells all use natural methods to clean dirty water.
Naturally occurring microbes break down waste products on a microscopic level. These microbes are abundant in wetland environments, which is why wetlands are such a productive ecosystem. These same microbes are what power a microbial fuel cell, which collects small amounts of energy from chemical reactions that break down waste. Aquaponics takes thsese relations a step further and uses the byproducts of these reactions as a type of fertilizer to grow plants.
Combining these technologies is a revolutionary step that brings us closer to a zero waste society.
