Abstract
This article examines household plastic recycling in Finland through two qualitative studies and four design concepts. Study 1 reports short interviews with residents about how they store, sort, and dispose of plastic packaging in their homes. The findings highlight recurring frictions: limited space, improvised storage, uncertainty about correct sorting, and difficulties with bulky or dirty items. Study 2 focuses on laundry detergent packaging as a common source of large plastic containers. Participants' purchase decisions prioritised price and cleaning performance, while expressing concern for environmental impact and confusion about materials, rinsing, and recyclability. Building on these insights, four student groups designed interactive recycling concepts that combine physical bins or bags with mobile applications. The concepts explore modular storage, sensing and compaction,…
