For India's Silicon Valley, aka Bengaluru, food is culture, connection and ritual. The city holds the record for the highest number of breakfasts ordered in India. But every meal leaves behind leftovers trapped in plastic dabbas (boxes), tossed away, often unwashed. For 22,500 informal waste pickers, it means hazardous work, indignity of sifting through stenchy, maggot-ridden, rotten food with bare hands, risking health and dignity.
Supported by H&M Foundation, BBC Media Action's #WashTheDabba campaign turns this invisibility into dignity. Born from the voices of waste pickers themselves, the campaign invites citizens to embrace a simple yet radical action: empty, rinse, and dry plastic food boxes, aka dabbas, before disposal. Leveraging co-created storytelling, cultural resonance, humour, and empathy, #WashTheDabba is a behavioural nudge catalysing a city-wide behaviour shift and creates new social narratives around dignity, work, and urban sustainability.
Since launch, the campaign reached 3.2 million people in Bengaluru and generated more than 15 million social media views. The message travelled through 136,000 food boxes from 36 restaurants, while 65 apartment complexes encouraged residents to adopt the practice. Independent evaluation showed strong results – 44% of respondents recalled the campaign without prompting, and 60% said they had started washing food boxes before disposing. Waste pickers at Dry Waste Collection Centres (DWCCs) also reported cleaner boxes.
The impact was systemic as well – Zomato, one of India's largest food delivery platforms, and a municipal government both adopted #WashTheDabba organically, embedding the practice into systems.
