The problem is that "industrial development" brings plastic bottles and plastic containers in country that do not have any trash collection system, let along recycling.
Most people in developing countries are used to throwing garbage anywhere because in the past, most garbage was compostable, so it was ok. But now garbage is mostly made of plastic, and people still do the same, the throw it away anywhere. there are no trash bins in cities, and very few cities have trash collection. Sometimes people pile-up trash and burn it, which is not good either when the trash contains lots of plastic.
My feeling is that corporations should be banned from selling plastic containers and plastic bags in countries that do not have trash collection and plastic recycling. In those countries, those corporations should subsidize plastic recycling and fund education programs if they want to sell their plastic junk.
But that requires political will and most local people are quite poor and they would not want to pay more for plastic stuff in order to fund its recycling.
