Harnessing the power of plants to harvest minerals, improve soil, and fuel the green transition.

Revolutionizing Mining with Plants

In a world seeking sustainable solutions, scientists at the University of Massachusetts Amherst (UMass Amherst) are making groundbreaking strides in environmental science. They’ve developed an innovative technique that uses plants to harvest critical minerals, such as nickel, which are essential for a clean, green economy. This technique, known as phytomining, could not only help extract valuable minerals but also improve soil quality and create biofuels for a cleaner future.

This research is pivotal as we transition to energy-efficient systems, including electric vehicles and energy-efficient batteries, both of which require minerals like nickel. Through this method, plants could play a crucial role in meeting the high demand for these materials in the green economy.

What is Phytomining? Turning Plants Into Miners

Phytomining refers to the use of plants to extract minerals from the soil, a process that mimics traditional mining but with significantly less environmental impact. The scientists at UMass Amherst are taking phytomining to the next level by engineering plants to become even more efficient at this process.

Camelina sativa, a plant in the mustard family, is at the center of their work. By modifying its genes, UMass Amherst scientists are aiming to make it as efficient as another plant, Odontarrhena (formerly known as Alyssum murale), which has the unique ability to hyperaccumulate nickel.

The Role of Hyperaccumulators in Phytomining

In the plant kingdom, there exists a special group of plants known as hyperaccumulators. These plants have the extraordinary ability to absorb and store large amounts of minerals, particularly metals, from the soil. Some plants can accumulate up to 3% of their biomass as nickel, making them ideal candidates for phytomining.

At UMass Amherst, Professor Om Parkash Dhankher is leading the charge in studying these hyperaccumulator plants. His team has been working tirelessly to enhance the natural capabilities of these plants to harvest critical minerals in an environmentally friendly manner. Professor Dhankher explains, “Conventional mining is monumentally destructive, but phytomining can provide us with a sustainable, domestic supply of nickel to help fuel the green transition.”

From Detoxing Soil to Harvesting Minerals

Professor Dhankher’s work began with the study of phytoremediation, a process where plants are used to detoxify and clean the soil. This technique works because plants naturally extract nutrients from the soil, and in the process, they can remove toxic substances like heavy metals. From this, it was a natural progression for his team to investigate how plants could be used for mineral extraction.

One plant that stands out in this regard is Odontarrhena, which has an unparalleled ability to hyperaccumulate nickel. While this plant is not ideal for widespread industrial use due to its invasiveness, it has provided crucial insights into how plants can absorb and store minerals. UMass scientists are now looking at how to replicate this process in a more widely usable plant—Camelina sativa.

The Challenge: Engineering Camelina sativa

The next challenge for the UMass Amherst team is to genetically modify Camelina sativa so that it can also hyperaccumulate nickel in the same way that Odontarrhena does. Camelina is already well-established in the U.S. as a plant that produces biofuels, so it is a sustainable material with potential for dual purposes: harvesting minerals and producing biofuel.

Professor Dhankher and his team plan to identify the genes and proteins responsible for nickel accumulation in Odontarrhena and transfer them to Camelina. They will also experiment with various soil amendments to see which ones will optimize the plant’s ability to absorb even more nickel.

Why Nickel Matters for the Green Economy

Nickel is a critical mineral for the green economy. It is an essential component in the production of energy-efficient batteries and electric vehicles, both of which are pivotal in reducing global reliance on fossil fuels. With the increasing demand for these technologies, there is a pressing need for a sustainable and domestic source of nickel.

Currently, only one company in the U.S. is engaged in conventional nickel mining, which is environmentally destructive. The UMass Amherst approach could provide a cleaner, more sustainable alternative by tapping into the natural mineral extraction abilities of plants. In fact, the soil in the U.S. contains traces of nickel in nearly one million acres of land, making it a potential goldmine for phytomining.

The Future of Phytomining: A Green Transition

If successful, the engineered Camelina sativa could provide up to 20-30% of the nickel demand in the U.S., which could significantly reduce the reliance on conventional mining methods. Professor Dhankher estimates that the U.S. could have enough nickel in its soil to supply up to 50 years of phytomining, which would support the growth of green industries for decades to come.

The shift to plant-based mining could also play a significant role in the global push toward a clean energy future. By reducing the need for destructive mining practices and utilizing plants to extract valuable minerals, this research represents a crucial step forward in the sustainable transition to a green economy.
