RE:rate of return on a torchA few others have attempted to calculate this in the past....based on the results from RISE when factoring in the operating cost savings and savings on carbon taxes in sweden, one plant with 50 torches would recoup the capital cost within 3 years if all were replaced. Of course this number changes based on the country's carbon tax laws.....regardless you can see that it is very much in the interest of all iron ore companies to make the switch to PYR torches as soon as possible!! Go PYR Go!!
