Can Australia make its own fertiliser without fossil fuels?
Australia is facing a fertiliser shortage that has prompted discussions about sustainable production methods. Currently, most fertilisers are derived from fossil fuels, making supply vulnerable to geopolitical tensions. Researchers are exploring alternative methods to produce nitrogen fertilisers without relying on fossil fuels.
- ▪Australia imports over 2 million tonnes of fertiliser each year, primarily made from fossil fuels.
- ▪The current fertiliser shortage is the third in recent years, exacerbated by global events like the COVID pandemic and the Russian invasion of Ukraine.
- ▪There is a growing interest in developing alternative methods for producing nitrogen fertilisers that do not rely on fossil fuels.
