Bangladesh banned thin plastic bags in 2002. We look at what worked, what didn’t, and why affordable compostable alternatives are the missing piece.
In 2002, Bangladesh did something no country had done before: it banned thin polythene shopping bags nationwide. The decision did not come from an environmental summit. It came from water. Catastrophic floods in 1988 and 1998 left the capital underwater for weeks, and investigators found that discarded polythene had choked the drainage system that was supposed to carry the water away. The ban was, first and foremost, a flood-control measure.
What worked
The ban put Bangladesh two decades ahead of the global conversation and proved that a developing economy could take plastic seriously. It raised public awareness, gave jute — the country’s own natural fibre — a moment in the spotlight, and became a reference point that dozens of other countries later followed.
What didn’t
Two decades on, thin bags are still easy to find. The gap was never the law; it was everything around it. Enforcement was thin and inconsistent. The promised push for jute and other alternatives was underfunded, so shopkeepers and customers were asked to give up a cheap, convenient product without an equally cheap, convenient replacement. When a ban removes a habit but leaves a vacuum, the habit tends to creep back.
The lesson for the next 20 years
A ban is a starting line, not a finish line. To actually displace single-use plastic, three things have to arrive together: clear rules, real enforcement, and an alternative that performs and costs roughly the same. That last piece is the one we work on — compostable bags and films that behave like the plastic people are used to, made locally so the price can compete, and certified to break down instead of fragmenting into the soil and water.
Bangladesh wrote the first chapter of this story. The unfinished part is making the better option the easy option.
