Grey Dhaka and Grameen Intel Social Business Ltd develop The Eco-Cooler: a zero electricity air cooler using cut in half recycled plastic bottles

Over 70% of Bangladesh’s population live in corrugated tin huts across the countryside. During the long summer months, temperatures reach up to 45° Celsius, making these huts unbearable to live in.

To address the issue, Grey Dhaka teamed up with volunteers from Grameen Intel Social Business Ltd to create the Eco-Cooler – the world’s first-ever zero electricity air cooler, which uses re-purposed plastic bottles cut in half and put into a grid, in accordance to available window sizes. Based on wind direction and airflow pressure, the Eco-Cooler has succeeded in decreasing the temperature in tin huts by up to 5° Celsius.

“Since most rural homes in Bangladesh are made with corrugated tin, the Eco-Cooler has the power to provide relief to millions of Bangladeshis. We sincerely hope this volunteer effort will make a difference in their lives”, said Abdullah Al Mamun, Deputy General Manager of Grameeen Intel Social Business Ltd.

“After initial tests, blueprints of the Eco-Cooler were put up online for everyone to download for free. Raw materials are easily available, therefore, making Eco-Coolers a cost-effective and environmentally-friendly solution”, said Syed Gousul Alam Shaon, Managing Partner and Chief Creative Officer at Grey Dhaka.

With the help of the Grameen Intel employees, the Eco-Coolers have been installed in villages in Nilphamari, Daulatdia, Paturia, Modonhati and Khaleya across Bangladesh.
