These signs were tested in a randomised controlled study for two common and perishable vegetables –…

However, only a small proportion of compostable food is currently composted. This is because of barriers to composting that are both structural (lack of public composting infrastructure) and psychological (insufficient knowledge about and interest in composting among prospective users).
We set out to develop a…
