A new biodegradable and compostable bag invented by a Bangladeshi scientist seeks to replace environmentally toxic polythene bags in the market. Sonali Bag, as it is called, turns into ashes when burnt, starts to dissolve into water within 4-5 hours, and degrades in soil within months. Made out of jute fibre, the bag is currently produced in a pilot project, but has both commercial and export potentials. Dr Mubarak Ahmad Khan, the award-winning scientist who invented the material, talks to The Daily Star as to how they made it happen and about his future plans.
