Chlorine has a huge variety of uses; as a disinfectant and purifier, in plastics and polymers, solvents, agrochemicals and pharmaceuticals, as well as an intermediate in manufacturing other substances where it is not contained in the final product. Chlorine is used worldwide to purify water supply as the ultimate defense against waterborne microbiological infection. Modern day cholera epidemics in Peru, China, India or Africa exemplify the devastating consequences of poor sanitation. Chlorine also plays a critical role in the productions of thousands of commercial products. Products reliant on chlorine’s unique properties include every household item such as bleach and disinfectant to bullet-resistant vests, computer hardware, silicon chips and automotive parts.
