They are not only trading it for environmental saftey. As mentioned in another comment, using these balls you don't have to rely on specialized rail waggons anymore. So, while you may lose some space due to inefficient packing, you could easily make that up by using lots more of (assumedly) cheaper general-purpose/coal waggons.
- PeterisP 9y agoSpecialized rail wagons aren't expensive compared to other parts of the transportation costs - if you have the option of 5 specialized wagons or 6 "cheap" wagons, then using 5 wagons is cheaper.
