While I agree with you that RWD won't generate $100M year in profits from Beyondie, the projected growth of the fertilizer industry is about 4.5% compounded out to 2030. The current global value of potash sales for 2023 is about $23 Billion with sales expected to increase by 7% PA through at least 2027 (or, doubling roughly every ~10 years) https://www.thebusinessresearchcompany.com/report/potash-global-market-report. Russia's war on Ukraine (and, in reality, the West) isn't likely to end anytime soon meaning the supplies of fertilizer coming out of Russia and Belarus will not improve in the foreseable future. China is short of water and arable land hence the pressure is on to maximise output of crops.

Australia's fertilizer industry is worth ~$USD 1.6 billion annually, of which about ~15% is Potassium based fertilizer, or about $USD 240 million https://www.grandviewresearch.com/industry-analysis/australia-fertilizers-market-report. There is no reason why RWD couldn't supply a significant chunk of that, assuming the RWD process works. Big if, but if your choice was backing RWD and its new technology or one of the old players trying to get flotation to work where would you place your bet?
