Commissioner questions plastic claims

As the tide turns against plastic, manufacturers have started to make their products more appealing by labelling the packaging as “degradable”, “biodegradable” or “compostable”.

But an inquiry by Parliamentary Commissioner for the Environment Simon Upton found the claims are not only confusing but often misleading.

“Businesses and consumers face a bewildering array of claims about plastic that can lead to misunderstandings on the part of even the most environmentally conscious citizens,” he said.

Biodegradable and compostable claims don’t mean much unless they’re backed by good standards and the waste can actually be processed. Your compostable coffee cup may be compostable but only if it’s delivered to a commercial composting facility. If there isn’t one, it will end up at the landfill.

To cut through the confusion, the commissioner wants the government to investigate standards and labelling requirements for biodegradable and compostable packaging. There are currently no New Zealand standards.

We support the commissioner’s call. Consumers opting for greener products should be able to trust the claims.
