The study was carried out by the Vienna-based Institute of Waste Management at BOKU University of Natural Resources and Life Sciences. Considerable amounts of used beverage cans are collected by waste-pickers, particularly in South-Eastern European countries like Romania, Greece and Hungary. The study estimates that each individual informal collector amasses an average of 1.6 kg of used beverage cans per day.
Raphael Thevenin, Chair of European Aluminiumâs Packaging Group said, âFormally counting cans that are already collected informally is an easy way to boost official recycling rates. Not only that, but it will more accurately reflect the true recycling practices of each country.â
One tried and true method is the widespread installation of Voluntary Take-Back Machines. By placing close to 200 machines in strategic locations such as supermarkets, in just five years the Hungarian Returpack system captured 15-20% of the countryâs total market for used beverage cans, representing 58% of all informally collected cans. Similar machines were recently installed in Romania. Collection machines ensure fair payment in exchange for the raw material. They also have the added benefit of inciting behaviour change by involving consumers in the act of recycling.
However, these machines alone cannot fix the problem. Extended Producer Responsibility (EPR) collection schemes continue to play an important role in formalising the informal. EPR schemes are particularly effective when suited to the unique needs of the countries where they operate. According to the study, existing schemes can nevertheless be improved: better designed bins can help combat the theft of valuable aluminium packaging scrap.
To boost the formal collection of beverage cans, the aluminium industry can also partner with recognised scrap dealers, provided that they respect scrap prices and conduct business transparently with local collectors. A major hurdle to the collection of scrap is the strict ID control of individual collectors who simply wish to earn a small income. The study found that relaxing administrative requirements would encourage local waste-pickers to bring back a few cans on a voluntary basis.
âThe European aluminium industry is committed to recycling. As a permanent material, aluminium is a key contributor to the circular economy. But as this study shows, additional investment and effort is needed to ensure valuable scrap like aluminium beverage cans stay in the official recycling loop,â said Thevenin.
The study was conducted in view of the recycling targets for aluminium packaging proposed in the European Commissionâs Circular Economy package. Recycling rates for aluminium beverage cans in Europe are already above 70%, but the industry is ambitious. While the EU is discussing a target of 75% by 2025, European Aluminiumâs members are aiming to reach 80% by 2020.
