Biodegradable chelating agents from phytoextractive plants
Discover biodegradable chelating agents from phytoextractive plants that naturally bioaccumulate metallic compounds like iron. This innovation utilizes a vast plant collection to identify agents selective for ferric ions, offering sustainable solutions for industries.
Overview
This research focuses on discovering biodegradable chelating agents derived from phytoextractive plants, which naturally bioaccumulate metallic compounds such as iron. By leveraging a significant collection of plant specimens, the goal is to identify chelating agents that are both effective and environmentally sustainable. This innovation aims to provide industries, such as consumer goods and manufacturing, with green alternatives to traditional chemical agents.
Technical specifications
The core of this research involves the use of phytoextractive plants, known for their ability to bioaccumulate metals, as sources of biodegradable chelating agents. These agents are screened for their selectivity to ferric ions using advanced techniques like x-ray analysis. The process includes:
- Screening a collection of 4 million plant specimens
- Identifying hyperaccumulative plants with specificity for ferric ions
- Utilizing x-ray technology to ensure selectivity and efficacy
Technology readiness level
Currently at TRL 2, this technology is in the early stages of development, with ongoing research to validate the hypothesis through advanced screening and selection methods.
About BIOMEDE
Biomede is a French startup specializing in phytoremediation, a natural technology that uses hyperaccumulating plants to extract heavy metals from contaminated agricultural and urban soils. Founded by Ludovic Vincent and Patricia Gifu, the company provides a comprehensive service that begins with a soil pollution diagnostic using X-ray technology to map the presence of contaminants. Based on this data, Biomede designs a customized seed mixture for the landowner, who then manages the planting and harvesting process. This nature-based solution is designed to restore soil health in a sustainable way, allowing land previously impacted by heavy metal accumulation—such as excess copper in vineyards—to remain productive or be returned to agricultural use. In line with circular economy principles, the company also explores methods to recover and reuse the extracted metals.
The startup's services are critical for farmers and urban agriculture projects facing land degradation, which can limit food production and impact environmental health. By providing an ecological alternative to traditional physico-chemical soil decontamination methods, Biomede helps landowners comply with environmental standards and improve the long-term quality of their plots. The company has gained recognition for its innovation, working with numerous prestigious wine appellations in regions such as Bordeaux, Burgundy, and Champagne. Biomede has received support from organizations like the AgroParisTech foundation and the ESA Business Incubation Centre, and it maintains partnerships with entities like Demeter to expand access to its soil regeneration solutions for international agricultural practitioners.
