Research carried out by the respected Netherlands Organisation for Applied Scientific Research (TNO), has confirmed the eco-efficient performance of steel packaging. The study reinforces the results of a 2005 report, also undertaken by TNO, and demonstrates that almost 10 years later the steel can is still one of the best eco-performers and the most eco-efficient rigid packaging option by far.
Commissioned by APEAL, the Association of European Producers of Steel for Packaging, the study analysed the performance of 600 grams of carrots and their packaging through their entire life cycle from food crop, picking and packing to consumption and recycling. Performance was analysed in terms of environmental impact and cost for the consumer, seeking to provide information on the overall value of different packaging solutions for society.
The study identified the comparable eco-efficiency of carrots packaged in steel cans, in a carton, in a pouch or freshly peeled. Food waste was highlighted as having a significant impact on the results. Results of the study also indicated the extent to which increased light-weighting and greater recycling rates will improve the eco-efficiency of steel packaging further.
The study assessed the cost and environmental efficiency of a range of packaged food systems. The formats were then assessed based on environmental indicators and a range of human and eco-toxicity factors.
