Dhaka city polls: Plastic-coated posters to take '400 yrs' to decompose

Dhaka is awash with millions of plastic-laminated campaign posters used for election campaigns in the Bangladeshi capital, and environmentalists are up in arms.

These posters -- of which there are an estimated 304 million -- will likely end up in sewers, rivers and canals, says activist Sharif Jamil.

"If they are burnt, they will pollute the air," he adds.

The city's air quality has been ranked one of the worst in the world.

"The posters will take 400 years to decompose," says Jamil, who is general secretary of the Bangladesh Environment Movement, a campaign group.

Each contains about two grammes of polypropylene plastic, according to the Environment and Social Development Organisation (ESDO).

Spokesman Hossain Shahriar told AFP the plastics were non-biodegradable and non-recyclable.

"We will be choking under these plastics since we don't have proper recycling mechanisms in the city," he said.

Bangladesh's High Court last week ordered a halt to the production, display and disposal of plastic-laminated posters for the mayoral and council elections, which is currently underway.

But to no avail. Black-and-white posters continue to festoon the streets and parks of the congested, cacophonous metropolis of 18 million people.

Manjur Hossain, head of Dhaka City Corporation's waste management department, said they would deal with the waste after the polls.

"We will separately manage it," he told AFP.
