Helping to protect the climate with reverse vending systems
In the fiscal year 2014/2015, we used a life-cycle assessment program to measure the carbon footprint of our reverse vending systems for PET bottles. In addition to PET bottles, other methods of packaging are often used, e.g., aluminum cans. Not only do these have different properties; they also use different materials. During the year covered by this report, we conducted the same analysis for aluminum cans in order to compare their environmental impact with that of PET bottles.
The analysis was based on two scenarios.
- The first of these involved the production of an aluminum can from new materials, its use and subsequent incineration, and the production of a new aluminum can using new material.
- The second involved the production of an aluminum can from new material, its subsequent use and return via our Revendo 9020 reverse vending system, and finally its recycling and the production of a new aluminum can from recycled material.
Our analysis showed that the recycling process (scenario two), which is made possible by our reverse vending system, leads to a saving of 110 g of CO2 per 0.5 liter aluminum can compared to scenario one. Based on a daily consumption of 3 liters of water, for example, this means a saving of approximately 240 kg of CO2 per person per year.
