Some familiar household synthetic polymers include: Nylons in textiles and fabrics, Teflon in non-stick pans, Bakelite for electrical switches, polyvinyl chloride (PVC) in pipes, etc. The common PET bottles are made of a synthetic polymer, polyethylene terephthalate.

Almost all plastic is non-biodegradable and without recycling, spreads across the environment [112] [113] where it causes plastic pollution. For example, as of 2015, approximately 8 million tonnes of waste plastic enters the oceans annually, damaging oceanic ecosystems and forming ocean garbage patches. [114]
While the patch contains more obvious examples of litter (plastic bottles, cans, and bags), tiny microplastics are nearly impossible to clean up. [52] National Geographic reports that even more non-biodegradable materials are finding their way into vulnerable environments – nearly thirty-eight million pieces a year. [53]
A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44] An example of a non-biodegradable bioplastic is bio-based PET. PET is a petrochemical plastic, derived from ...
Almost all plastic is non-biodegradable and without recycling, spreads across the environment [8] [9] where it causes plastic pollution. For example, as of 2015, approximately 8 million tonnes of waste plastic enters the oceans annually, damaging oceanic ecosystems and forming ocean garbage patches. [10]
For example, mealworms fed only on plastic show very little weight gain, unlike mealworms fed on a normal diet of bran. [5] This is due to plastic lacking water and nutrients needed to grow. [ 5 ] Plastic-fed mealworms can still derive energy from their diet, so they do not lose weight like starved mealworms do.
A fatberg is a rock-like mass of waste matter in a sewer system formed by the combination of flushed non-biodegradable solids (such as wet wipes) with fat, oil, and grease (FOG) deposits. [1] [2] [3] The handling of FOG waste and the buildup of its deposits are a long-standing problem in waste management, with "fatberg" a more recent neologism. [4]
