BASSTA Plus: helping urban households sort waste

Making benefits tangible

The Netherlands has set a goal of being fully circular by 2050. Effectively sorting waste, so that it can be used as a raw material for new products, is a crucial aspect of this. Yet it remains difficult to persuade residents – particularly those in high-rise buildings – to always separate their waste before tossing it in the bins.

As it stands now, residents often lack the knowledge and motivation it takes to sort their household waste properly. To actually change behaviour, however, you need more drastic interventions that make separating waste flows easier and make the benefits of doing so tangible.

Various behavioural interventions

In BASSTA Plus, AUAS is cooperating with municipalities, waste collection companies and other social organisations to explore which interventions (or combinations of interventions) encourage proper waste-sorting behaviour. A variety of behavioural interventions are researched, including a starter’s package, setting targets for specific groups, informative surveys and using the bin itself as a means of communication. Residents are being involved in the project through field research that tests the interventions in real-world circumstances.

Instructions for municipalities

Would you as a municipality or waste collector like to know more about how residents feel about the separation of organic waste, and at the same time stimulate them to separate their organic waste (better)? In that case, the following information survey could be an interesting solution.

A behavioral intervention that can contribute to increasing the opportunity to separate organic waste is to offer a organic waste bin and bags. But what type of bin is best to offer to residents, do you give a choice or not and how can you best arrange?

Education

Students in the Applied Psychology, Product Design and Communication & Multimedia Design programmes at AUAS take part in the research. The students help develop and test the interventions.

Partners

There are eleven partners in the consortium: Amsterdam University of Applied Sciences, the municipalities of Amsterdam, Amersfoort, The Hague and Alphen aan den Rijn, ROVA and Avalex (regional waste collection companies), Rijkswaterstaat, the Dutch Association of Waste Processing Companies (NVRD) and Milieu Centraal, the Dutch public information service on energy and the environment. The municipality of Rotterdam is also involved in the project. If you are interested in participating, please contact the project team.

Successor to BASSTA (2021-2023)

BASSTA Plus is the successor to the BASSTA project (2021-2023), in which AUAS researchers gathered detailed information on how people living in flats in Amsterdam, Utrecht, Alphen aan den Rijn and other cities manage their household waste, from the moment the waste is created in their homes to when they deposit in a bin outside. They also developed and tested a number of interventions in cooperation with social organisations, municipalities and other government bodies.
