In a bid to promote itself as one of the more eco-friendly and environmentally aware supermarkets, Sainsbury’s has managed to create some controversy with its announcement that it’s moving its Basics canned tomatoes into cartons, part of its attempt to cut its packaging weight by a third by 2015.
Whilst you can’t knock the supermarket chain for taking the initiative and demonstrating its commitment to the environment (although let’s not forget this is driven by the imposed light-weighting targets), it’s equally important that people such as Nick Mullen from the Metal Packaging Manufacturers Association are taking a stance on this and publically reminding key industry stakeholders of the potential issues that surround presenting one packaging material as environmentally superior to another.
As a result of this quick action, Sainsbury’s immediately issued a statement to confirm that this move doesn’t signal the end of the can for them. All good and well although, many would argue, the damage is already done. Short term, this is probably true. However, it’s a far wider and longer-term issue that needs to be addressed by all stakeholders.
We mustn’t lose sight of the fact that each material has its own unique environmental attributes. One of the key green credentials for metal is the low residual waste that is a result of high recycling rates and their associated carbon credits that are vitally relevant, as opposed to the weight of packaging brought to market.
Any pack mix decisions that purport to be made on environmental grounds that do not include this vital element are deceiving themselves and only helping to confuse consumers. Still, a decision has been made in this instance and, ironically, due to the immediate criticism and reactive comment from Sainsbury’s Head of Packaging, this move has indirectly generated debate on the importance of a better understanding of the contribution each packaging material can make towards sustainability goals rather than seeing ‘easy’ solutions by changing to alternative materials.
