Evraz has been expanding and is cranking out 300+mt an hour.
100% recycled steel cooked with clean and green wind, co-gen, hydro and carbon captured coal.
Arcelor Mittal is doing just fine too and is recycling using hydro.
SO2 Cap and Trade killed the Canadian new steel industry and Carbon taxes entombed it to history.
Does that include greenhouses to capture the CO2?
Where is all the metal going, in Canada or is the export market taking it as a raw product?
Taking hemp from no place to being farmed at 21st century standards would keep designers and manufacturers busy for 20 years at that rate and it is all used in house. The return for a $20B investment, an industry based on renewable raw resources and in a volume that would employ more than Detroit Auto makers ever did. The competition has to dry up on it's own rather than collapse due to a better product being marketed.
Canada's industries fit in with global manufacturing rather than we produce what we want and the world just happens to need that when it becomes available.
When heavy oil from Venezuela became unavailable the US upped the export from Ft Mac. At the same time they cut the oil and gas imports so overall Canada saw no increase in exports. That is because the global market is already a monopoly where all moves help the monopoly rather than the customers it should serve. When viewed like that you should be able to predict what projects will go a head and what will be put on the back burner. Electric cars would seem to be going to the back burner now they know how to build them they can move onto another R&D program the public will be suckered into funding. If that is the case hemp would make a great product to research only it would grow rather than get shut down. We don't have that kind of permission so the existing options are part of the 'pay to play'.
Marketing the tar sands as 'water-proof gravel' would have waterlogged countries ordering it for building roads across 'muck'. With some matting you can control the depth needed, without the matting you use as much as needed, when it stays above the much that is the right amount.
