2 . We're so attached to plastic, but we're careless consumers. Waste plastic is entering our ecosystems and food chains with untold consequences. Cleaning up our polluted world of plastic may seem a noble, but thankless task. However, some people are seeing economic opportunity in the mission.

Plastic Bank, a social enterprise from Canada, is monetizing plastic recycling while empowering those most affected by the waste. It works to prevent waste plastic from entering oceans by encouraging people in developing countries to collect plastic from their communities in exchange for cash, food, clean water or school tuition for their children. After collection, plastic is weighed, sorted, chipped, melted into balls and sold on as“raw material”to be made into everything from bottles for cleaning products to clothing.

“I saw in large quantities; I saw an opportunity,”CEO David Katz told the audience at the Sustainable Brands Oceans conference in Porto, Portugal on November 14.“We reveal the value in this material,”he added.

Plastic Bank was founded in 2013 and launched on the ground operations in 2014 in Haiti, the poorest country in the Western, Hemisphere, where close to 60% of the population live under the poverty line. As result of poor waste disposal and recycling infrastructure (基础设施)，plastic waste enters rivers or is burned and poses the health threats to the local residents.

The company says i has over 2,000 collectors working in the country, with its full- time collectors on average 63% above the poverty line thanks to the income they make from the project. Through its app based payment system, many collectors now have bank accounts for the first time, and are able to ultimately escape ultra poverty.

“Nothing we're doing is against the laws of physics,”said Katz. “All the technology exists for us to solve and save the world. It's only creative thought.”
