Project: Reduce, Reuse, Recycle

The "Reduce, Reuse, Recycle Stockholm Royal Seaport" project aims to demonstrate and explore how digital technology can improve waste sorting to enhance recycling and be implemented at district level.

The project is run by Stockholm Vatten och Avfall together with KTH, The Royal Institute of Technology, the University of Agder, and several property owners in the Royal Seaport area.

Purpose and goal

The project aims to improve waste sorting efficiency, achieve cleaner waste fractions and reduce residual waste.

Project participants will have access to the Envac Reflow app, which allows them to:

• Report issues with waste inlet points
• Receive feedback on waste volumes
• Access information about waste sorting

Results and experiences

In Stockholm Royal Seaport, 550 households took part in the project and used the Envac Reflow app. According to the latest survey, more than 60 per cent of users have improved their knowledge of waste sorting. Waste composition analyses in the area have confirmed these improvements.

Two waste analyses, conducted during different seasons, revealed the following improvements:

• A nearly 20 per cent reduction in incorrectly sorted packaging and newspapers found in residual waste
• A 10 per cent increase in correctly sorted plastic packaging
• Overall, the analyses showed less contamination in residual waste, with decreased levels of incorrectly sorted food waste across all vacuum collection fractions.

The service expanded in 2024, enabling approximately 2,950 households to participate.
