UK Scientist Awarded Innovative Prize for Groundbreaking Invention to Prevent ‘Phosphogeddon’

Phosphorus is often overlooked, but it plays a crucial role in agriculture. It’s a main ingredient in fertilizers that help feed the world’s growing population. However, there’s a downside. When phosphorus compounds, known as phosphates, wash into our rivers and lakes, they can lead to harmful algal blooms. These blooms consume oxygen and kill fish and marine life, creating serious environmental issues.

A company called Rookwood Operations, based in Wells, Somerset, is working on a solution. They’ve developed a product that removes excess phosphates from polluted water and repurposes them for farming. This innovative approach not only helps clean our waterways but also enhances soil quality.

Jane Pearce, one of the founders of Rookwood Operations, is making waves in the industry. She’s recently received a £75,000 Innovate UK Women in Innovation Award for her efforts. Pearce highlights the goal of their project: “We aim to transfer phosphates from rivers and lakes, where they harm ecosystems, to farmland, where they can nourish crops.”

The secret behind this solution is a natural material called Phosphate Removal Material (PRM). It’s like a sponge that absorbs phosphates from water. Once it’s saturated, it can be moved to fields, where it enriches the soil and supports crop growth.

Phosphates are vital for living organisms; they’re found in our bones, teeth, and even in DNA. Yet, phosphorus reserves are diminishing. Only a few places, like Morocco and China, have significant amounts. The U.S. has seen its reserves decline to just 1% of previous levels. The UK relies on imports, which isn’t sustainable.

Alongside the depletion of resources, poor management of fertilizers allows phosphates to run off into the environment. This runoff creates algae blooms, which can turn clear rivers into green, murky water, as seen in many polluted British rivers, like the River Wye.

Amidst these challenges, Rookwood Operations is stepping up with PRM. Pearce hopes their material will stabilize phosphate use and reduce reliance on imported supplies, benefiting both the environment and agriculture.
