Merely providing a collection service that ensures waste segregated at source is not mixed during transportation is not enough to induce households to segregate. Information campaigns are a must.
This research brief is based on the EfD Discussion Paper titled Disentangling the chicken or egg problem of household waste sorting and segregated waste collection: A randomized control trial in India by authors Shivani Wadehra, Zihan Nie, and Francisco Alpizar
About the study
▪ We aim to disentangle this chicken-egg problem with a large-scale intervention that provides a guaranteed segregated collection service.
▪ We evaluate different approaches to promote waste segregation at source.
- Specifically, we examine the effect of a one-shot segregation promotion campaign involving information and in-house sorting devices.
- For a subgroup of the campaign treatment, we also provided periodical reminders to the households.
▪ We also explore the financial viability of such a segregated collection service.
