Most of the recent campaigns against plastics seem to be focussed on grocery bags – but this issue of the packaging material for CV/DVD is a bit more problematic. While (for the average consumer at least) less plastic waste quantity is generated from the wrapping of these items than from shopping bags, at least there is the option to reuse the plastic bags; it is difficult to think of any re-use for the plastic from wrapping CD’s…
Overall, the "plastics" environmental issue is really just another dimension of the cultural addiction to oil and gas. I have read previously, that the ready availability of plastics for making consumable / non-durable / disposable items such as grocery bags and packaging materials, is dependent upon the ubiquity of
ethylene as an industrial by-product of petro-chemical refineries.
As such, one of the arguments often presented by skeptics to campaigns to ban plastic shopping bags, or to reduce the quantity used in packaging materials, is that this very ethylene will still end up in the environment (and not in a form that creates any value).
However, one implication of the increasing unavailability of (or competition for) hydrocarbons as time progresses, is that reliance on cheap ethylene for plastics production (as a
de facto waste transfer mechanism) is in itself inherently unsustainable.
Therefore, this adds another dimension to the plastic materials sustainability debate – we should probably be looking for some substitute material for things like plastic bags (and bottles, packaging materials, etc.) for reasons other than their (direct) environmental impact.
However, it is instructive to note that the environmental "scourge" (as the anti-"plastic bags" campaigners describe it) will, like all other things related to fossil fuels, peak at some time. Unless a very cheap substitute source for plastic manufacture is found, it is only a matter of time before it is too valuable to be simply "given away". Source stocks for making plastics will always be available (e.g., from bio-polymers), but the fact remains that the allocation and distribution of this material will change in the short- or medium-term future.
