Hammerstone will supply base aggregates for construction purposes, as well as high-quality limestone aggregate for use in manufacturing concrete and calcinable limestone for production of quicklime.
Planned aggregate production rates, including calcinable limestone, grow from less than 1 Mt per year ("Mt/yr") in 2005 to more than 10 Mt/yr by 2016.
Argus introduced two calcinable
grades of green coke and one calcined coke assessment.
Assuming a base case demand for calcinable
petroleum coke, beginning in mid-2016 there could be a 2 to 3 year window which will see a tightening of calcinable
petroleum coke supply and potential deficit which will continue to grow.
