is plastic a mineral? Plastic is certainly not a mineral. Minerals need to fit into certain categories - as below to define a mineral A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement. This may seem a bit of a mouthful, but if you break it down it becomes simpler. * Minerals are naturally occurring They are not made by humans * Minerals are inorganic They have never been alive and are not made up from plants or animals * Minerals are solids They are not liquids (like water), or gases (like the air around you) * Minerals have a definite chemical composition Each one is made of a particular mix of chemical elements * Minerals have an ordered atomic arrangement The chemical elements that make up each mineral are arranged in a particular way - this is why minerals 'grow' as crystals So as plastic does not form naturally and do not have an ordered atomic arrangement and require oil to form with human intervention -PLASTIC can categorically not be a mineral.
