Based on its composition and expert assessment, polymer clay is generally not considered good for the environment.
Understanding Polymer Clay Composition
Polymer clay is a type of modeling material that hardens when heated. Its primary component is PVC (polyvinyl chloride), which is mixed with a plasticiser to make it pliable.
The basic materials used to create PVC are derived from:
- Salt: Used to produce chlorine.
- Oil: From which ethylene is derived.
The Environmental Impact of PVC
The use of PVC in polymer clay is the main reason for its negative environmental assessment. According to Greenpeace, PVC "is the most environmentally damaging plastic." This designation highlights significant concerns associated with PVC throughout its lifecycle, from production to disposal.
Why PVC is Environmentally Damaging
While the provided reference specifically points to the Greenpeace assessment, broader environmental concerns regarding PVC often include issues related to:
- The production process, which can involve harmful chemicals.
- The potential leaching of plasticisers (some of which can be phthalates) over time.
- Disposal, as burning PVC can release dioxins and other toxic pollutants.
Given its base material, polymer clay inherits the environmental drawbacks associated with PVC, making it a less environmentally friendly choice compared to natural or biodegradable materials.
