PET bottles, one of the most widely used materials in the world, are used to package foods and drinks from soda and juices to salad dressings and cooking oils. It is also completely recyclable. In the United States alone, 1.5 billion pounds of PET bottles are recycled annually.
Throughout my travels to low and middle-income countries I see PET bottles thrown haphazardly in fields and streams clogging waterways and dirtying sidewalks and walking paths. In countries such as Nepal (where I visited last year with Coca-Cola), there are concerted educational efforts by environmentally focused NGOs to change behaviors around discarding PET bottles. There are recycling centers in Nepal, but not enough to completely clean its streets and countryside. It seems to be a sisyphean battle to combat PET bottle waste, but there are some who are using the bottles in innovative ways.
