· With regard to the environmental impact, it must be noted that cast iron does not generally rust as it does not oxidise quickly. This process releases carbon-based iron ashes which does not harm the living environment around. They bring about the growth of plants and raises planktonic life in the ocean, thereby fighting global warming.
