Calcium looping example, adding Ca-looping to all coal-fired plants in the UK would generate enough waste for 33 Mtonnes/yr of cement production, whereas current cement production in the UK is only 12.5 Mtonnes/yr. Hence, if the technology is applied on a large scale, the purge rate of CaO should be optimized to minimize waste. To fully gauge the viability of calcium looping as a capture process, it is necessary to consider the political, environmental, and health effects of the process as well. Though many recent scientific reports (e.g.: the seven-wedge stabilization plan by Pacala and Socolow) convey an urgent need to deploy
Calcium gluconate one-gram vial, 10 ml of 100 mg/ml (10% solution). In the United Kingdom this amount costs the NHS about 0.65 pounds. 10% calcium gluconate solution (given intravenously) is the form of calcium most widely used in the treatment of low blood calcium. This form of calcium is not as well absorbed as calcium lactate, and it only contains 0.93% (930 mg/dl) calcium ion (defined by 1 g weight solute in 100 ml of solution to make 1% solution w/v). Therefore, if the hypocalcemia is acute and severe, calcium chloride is given instead. Calcium gluconate is used as a cardioprotective agent
