CO2 is used as fertilizer???
In typical fashion the media got the whole thing wrong.
In most?( all I have been to) fertilizer plants CO2 is a byproduct of making ammonia. Ammonia is the main ingredient. If the plant is shut down then they are not making ammonia and no CO2. All the plants I have been to had very large liquid CO2 tank(s). That way the food grade supply of CO2 wasn’t disrupted. There are not too many ammonia plants left in Europe. I believe the u.k. only had one left.
If the plant only had one tank and they happen to be making a repair or something else that requires them to empty the tank there would be no other reserves unless they brought in temporary storage, likely not worth the money, nor hassle, as there isn’t alot of money in CO2. I wonder if they had an unscheduled event happen and they have been down longer than planned or something else is effecting them.
That’s the problem with globalization. The effects that no one thinks about are the ones that get them. I have seen it a lot over the years.
