- Addition polymerisation, where monomers are added to each other via the breaking of the C=C bond
- Monomer is the repeat unit, repeated n times in the polymer
- Waste polymers processed by:
- Recycling (processed into new polymers)
- Burnt (for energy production)
- Chemical feedstocks (To make other plastics)
- Halogenated plastics are toxic when burnt, so this must be removed
- Plant-based polymers are biodegradeable, with no toxic waste
- Photodegradeable polymers have bonds that weaken in light, beginning the breakdown of the polymers
