Plastic and Environment A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass‚ but they often contain other substances. They are usually synthetic‚ most commonly derived from petrochemicals‚ but many are partially natural. Composition Most plastics contain organic polymers. The vast majority of these polymers are based on chains of carbon atoms alone or with oxygen‚ sulfur‚ or nitrogen
