Plant-e develops products in which living plants generate electricity. These products are based technology that was developed at Wageningen University, which was patented in 2007. The patent is now held by Plant-e. The technology enables us to produce electricity from living plants at practically every site where plants can grow. The technology is based on natural processes and doesn’t harm the plant or its environment.
Via photosynthesis a plant produces organic matter. Part of this organic matter is used for plant-growth, but a large part can’t be used by the plant and is excreted into the soil via the roots. Around the roots naturally occuring micro-organisms break down the organic compounds to gain energy from. In this process, electrons are released as a waste product. By providing an electrode for the micro-organisms to donate their electrons to, the electrons can be harvested as electricity. Research has shown that plant-growth isn’t compromised by harvesting electricity, so plants keep on growing while electricity is concurrently produced.
