Plastic is generally perceived as a synthetic material that can be easily shaped or molded into objects. The difficulty with the definition is that plasticity - the ability to be molded – is a property, not a substance, and therefore in terms of sustainability the term can be confusing as plastics can be plant -based or chemical, as well as biodegradable or persistent in the environment.
We recommend ironing out your definition of plastic in any plastics reducing/replacing project upfront.
