28 Feb Plant-E – Generation electricity with living plants
Founder: Marjolein Helder
It is Plant-e’s mission to provide a high-tech, nature-based solution by generating electricity with living plants. By using this technology, in addition to generating green electricity, they focus on reducing global methane emissions and treating waste water flows.
To make this possible, the Plant Microbial Fuel Cell (P-MFC) technology is used. This technology was developed at Wageningen University and was patented in 2007. Plant-e is now the patent holder and is constantly working on further research and product development.
How do they do that? A plant produces organic material through photosynthesis. Part of this organic material is used by the plant for its own growth, but not everything is used by the plant. This remaining part is excreted via the roots to the soil. In the soil, around the roots of the plant, bacteria break down the organic material. In this degradation process electrons are released as a waste product. The P-MFC technology ensures that we can use these electrons as electricity.
