Flexible Aluminum-Containing Laminate Collection Trial
Collection, Sortation, Processing, End Markets.
Three different communities, each with slightly different curbside collection programs, were provided with colored bags in which to collect a variety of aluminum-based multi-material packaging (including food & pet-food pouches and toothpaste tubes). Residents were instructed to fill the bag with defined packaging and set alongside with existing curbside recyclables. Bags were then sorted at a municipal facility and sent to pyrolysis for conversion into synthetic oil and recycled aluminum.
Data will be shared and built upon within the forthcoming CEFLEX project.
- Participation in the program waned the longer it was established. This follows the trend for introducing new materials for curbside collection.
- Odor issues from food based packaging (pet and human) was an issue across all phases of the program.
- The quality of the recycled aluminum produced was similar to that of pre-consumer material suggesting that this processing method is suitable for both post-consumer and pre-consumer scrap.
- Packaging volumes varied considerably between households. In many cases consumers felt volumes were too small or too infrequent to warrant consistent collection.
