Eggshell is the hard porous protective outer layer of a bird's egg, consisting of calcite and protein, a yellowish-white color, a type of paper with a slightly rough finishVinyl, or polyvinyl chloride (PVC) to give it its full name, is a synthetic plastic polymer that is tough and durable and also has flame-retardant properties. These qualities make it suitable for a wide range of applications, leading to it being labeled "the world's most versatile plastic".Vinyl is such an important material in the modern world that it's hard to imagine living without it. It has so many uses, and it is inexpensive and easy to work with.The challenge in the coming years will be to work out how we can continue to use vinyl - and other similar plastics - in a safe and ecological way that will reduce the lasting impact it has on the planet.
