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
Coral calcium Coral calcium Coral calcium is a salt of calcium derived from fossilized coral reefs (primarily from limestone and coastal deposits). It has been promoted as an alternative, but unsubstantiated, treatment or cure for a number of health conditions. Coral calcium has been promoted as an alternative treatment or cure for a number of health conditions, often as part of an alkaline diet, by Robert Barefoot and others; Barefoot coauthored a book called "The Calcium Factor," and marketed coral calcium supplements with infomercials. According to a "Time" magazine article about Barefoot by Leon Jaroff, "The monthly cost of the recommended dose
