Wow, I wonder how this will affect phosphate and fertilizer prices.
Phosphate is used as an input for these chemical processes, but the fraction of the phosphate production that is used for such processes is very small in comparison with what goes into fertilizers.
The only possible effect is a price reduction for some organic compounds of phosphorus, e.g. for some pesticides.
Some estimates put "Peak Phosphorus" as early as 2030 but unsurprisingly, that claim is highly contested.
