Steel cans reduce climate change impact
The Association of Producers of Steel for Packaging (Apeal) has confirmed that the impact on climate change of the average unit of steel packaging was reduced by 32% during 2000 to 2013.
A recent Life Cycle Assessment (LCA) of cans, conducted by European Metal Packaging (Empac) has revealed continuous improvement in the carbon footprint of steel cans across all the five product categories analysed including food cans, aerosols, general line cans, closures and speciality tins.
The reduction in CO2 equivalent has been attributed by Empac to three factors:
- Continuous improvement in recycling rates,
- Continuous improvement in unit light weighting,
- Increased amounts of green energy used for the packaging manufacturing process.
The study also measured the net water consumption, which is a key component when assessing a product’s environmental footprint. The results confirm that steel packaging reduced impact on water depletion by an impressive 60% per average unit between 2006 and 2013.
Stéphane Tondo, president of Apeal, said: “Life cycle thinking is vital for the future and for moving towards a circular economy. This new study demonstrates how steel as a material contributes to the sustainable development of the can. It is important that our customers, and all our stakeholders, have the full picture so that they can make informed and sustainable choices about packaging.”
