Since their invention in the 1960s, disposable plastic bags have made lives easier for lazy shoppers the world over. But once used, they become a blight. This is particularly true in poor countries without good systems for disposing of them. They are not only unsightly. Filled with rainwater, they are a boon for malaria-carrying mosquitoes. Dumped in the ocean, they kill fish. They may take hundreds of years to degrade. On March 15th Kenya announced that it will become the second country in Africa to ban them. It follows Rwanda, a country with a dictatorial obsession with cleanliness, which outlawed them in 2008…
As Kenyans get richer and move to cities, the amount of plastic they use is growing. By one estimate, Kenya gets through 24m bags a month, or two per person. (Americans, by comparison, use roughly three per person.) Between 2010 and 2014 annual plastic production in Kenya expanded by a third, to 400,000 tonnes. Bags made up a large part of the growth.
Kenya has tried to ban polythene bags twice before, in 2007 and 2011, without much success. This latest measure is broader, but few are ready for it. The Kenyan Association of Manufacturers says it will cost thousands of jobs. Some worry that supermarkets will simply switch to paper bags, which could add to deforestation. And then there is the question of whether Kenyan consumers will accept it. In Rwanda, since its ban was imposed, a thriving underground industry has emerged smuggling the bags from neighbouring Congo.
