Plants inspire scientists to recover minerals, metals from wastewater

In their view, the technology could benefit a range of industries such as agriculture, aquaculture, desalination, battery recycling and mining. It could also help companies rethink their approach to how they deal with waste by creating a way to extract value from wastewater.

The paper notes that it is estimated that global wastewater contains three million metric tons of phosphorus, 16.6 million metric tons of nitrogen and 6.3 million metric tons of potassium. The recovery of these nutrients from wastewater could offset 13.4% of global agricultural demand for these resources.

The ammonia and hydrogen molecules, among others, that are embedded in wastewater could provide electricity to 158 million households.

“The world’s wastewater contains a jumbled mess of resources that are incredibly valuable, but only in their pure form. A big challenge researchers face is figuring out how to efficiently extract these valuable minerals, metals and nutrients while retaining their purity,” ANU plant scientist associate professor, Caitlin Byrt, said in a media statement. “The Australian mining industry for example creates more than 500 million tons of waste per year, and these wastes are rich in resources like copper, lithium and iron. But at the moment, liquid waste is just a problem; it can’t be dumped and it can’t be used. It’s just waste unless each resource can be separated out in a pure form.”

Separating the good from the bad

Byrt and her colleagues investigated the specialized molecular mechanisms that help plants recognize and separate different metal, mineral and nutrient molecules contained in soil, allowing them to sort the good from the bad—a basic biological process necessary for their growth and development.

“Resources such as boron, iron, lithium and phosphorus are used in battery technologies and plants are masters at separating these types of resources,” Byrt said.

Ammonia, a compound used to create fertilizer and an essential material in crop production, is another key resource scientists are looking to extract from liquid waste solutions.

“Fertilizer costs are going through the roof, which puts a lot of pressure on Australian farmers to be able to afford these higher prices and yet we’re wasting huge proportions of these molecules and that’s causing environmental problems,” Byrt pointed out. “Ammonia is also a critical storage molecule for hydrogen fuels. So, as we continue to develop hydrogen fuel industries, there will be an increase in demand for ammonia for use as a storage molecule, because that’s how the hydrogen fuel industry will be able to transport the stored hydrogen around and ultimately use it as a potential fuel source for fuelling cars and other technologies.”

For the researcher, advances in precision separation technology could also offer security to flood- and drought-prone communities by providing them with portable, secure and reliable access to clean drinking water in the face of worsening weather events as a result of climate change.

“Clean water and the security of nutrient resources underpin agricultural productivity. Development of technologies to sustainably manage these resources is essential for food security in Australia and globally,” she said.
