Dr Lorna Anguilano and her team at 明星八卦’s Experimental Techniques Centre are transforming how we address environmental challenges. Their research uses plants to clean contaminated soils and recover valuable minerals in the form of nanoparticles. This sustainable solution improves soil health and benefits the environment, local economies and communities at the same time.

Unlocking the power of phytomining
Phytomining: the science behind the success
What sets Lorna’s research apart is its innovative approach. Instead of genetically modified plants, her team uses natural plant combinations, creating biodiverse areas that improve the local ecosystem. Phytomining involves using so-called hyperaccumulator plants which absorb metals from the soil. These plants are carefully selected for their ability to thrive in these specific environments to draw metals like lithium, cobalt, and rare earth elements.
As the next step, Lorna’s team uses bioprocessing techniques in the lab to extract metals from the plants without burning the biomass. This method is energy-efficient and environmentally friendly. After recovery of the metal-bearing nanoparticles the clean residue from the plants is repurposed for various applications, such as reinforcement materials for construction and generating monomers for bioplastics. Even the liquid fraction of the biomass is used as a fertilizer, further contributing to soil regeneration. The plants can also be composted, adding another layer of sustainability to the process.
Impact that extends beyond the lab
One of the most exciting aspects of Lorna’s work is its accessibility. Through collaborations with local councils and international partners, her research is revitalizing communities, creating job opportunities, and promoting a circular economy.
The principles of phytomining can be applied by everyday gardeners too. By using specific plants, gardeners can help clean their soil. This makes Lorna’s research not only groundbreaking but also practical for anyone interested in sustainable gardening. It empowers individuals to contribute to environmental cleanup in their own backyards.

The team’s commitment to public engagement is evident in their large-scale citizen science projects, which have garnered recognition from the European Union in 2023. These projects have involved hundreds of participants, demonstrating the widespread interest and potential impact of phytomining.
Internationally, Lorna’s team collaborates with partners in Japan, Taiwan, and the Philippines, expanding the reach and impact of their research.
