Funding Raised · Wageningen, Gelderland · founded 2009 · 31 employees$5.8Mraised▾
Plant-E is focused on developing products in which electricity is generated from living plants. The patented technology was developed at Wageningen University which claimed that during photosynthesis, when the plant produces organic matter to be used for its own growth, a large part of the matter can’t be used by the plant and is excreted into the soil via the roots. In the soil, naturally occurring bacteria break down the organic matter and release electrons in the process. The company is developing a system that can be applied in existing wetlands where a tube system is placed beneath the surface of the ground, in the root area of plants which, using the technology, makes it possible to use the electrons released by the bacteria for generating electricity. Currently, the company has created two modular units in two different sizes that can be purchased from their website itself.
