Plastics are produced in chemical plants by the polymerization of their starting materials ; which are almost always petrochemical in nature. Such facilities are normally large and are visually similar to oil refineries, with sprawling pipework running throughout.

- Plasticity
The directive aims to reduce plastic pollution from single-use disposable plastics. It focuses on the 10 most commonly found disposable plastics at beaches, which make up 43% of marine litter (fishing gear another 27%).
17 Οκτ 2024 · In this article a brief review of the essential properties of plastics is provided, followed by a more detailed description of their processing into useful products and subsequent recycling. For a fuller understanding of the materials from which plastics are made, see chemistry of industrial polymers.
16 Μαΐ 2022 · Plastics are (mostly) synthetic (human-made) materials, made from polymers, which are long molecules built around chains of carbon atoms, typically with hydrogen, oxygen, sulfur, and nitrogen filling in the spaces.
What is plastic, how is it made, and can it be recycled? What are bioplastics, BPA and other additives? Read everything you need to know about plastic.

Two main processes are used to produce plastics – polymerisation and polycondensation – and they both require specific catalysts. In a polymerisation reactor, monomers such as ethylene and propylene are linked together to form long polymer chains.
