A new study from The Australian National University (ANU) has devised a method that transforms waste into a new fertilizer.
The fertilizer is cleaner to produce and more effective than those currently on the market. It was developed in partnership with the Grains Research and Development Corporation and CSIRO.
The process takes pollution from waterways and carbon dioxide from the atmosphere and uses them to create an otherwise rare fertilizer – so it not only helps grow food but also reduces pollution.
The fertilizer combines ammonia, a public waterway pollutant, and carbon dioxide to supply citrulline. Citrulline is discovered naturally and besides, occurs to be rich in nitrogen – which is essential for plant growth.
Citrulline’s potent for such a treatment had not been considered previously.
Dr. Lee Alissandratos from ANU said early plant trials carried with CSIRO had produced “auspicious” results.
“The plants that were supplied citrulline grew even higher than the ones on urea – a widely employed nitrogen fertilizer,” Dr. Alissandratos said.
“But citrulline solely happens naturally in relatively small quantities, so its potential use as a fertilizer depends on the availability of proper production methods.
“We have addressed this via a new process that’s each efficient and green as it uses pervasive environmental pollutants as the raw materials.”
Dr. Alissandratos said the new method not solely had environmental pay-offs but was a money saver.
According to Dr. Alissandratos, the researchers’ new method offers a complete host of benefits.
Our method is way more sustainable. It makes use of enzymes – nature’s catalysts – and is carried out in the water with little energy enter and without toxic by-products.
Dr. Alissandratos and his team are now assessing commercial applications of their method.
