The lesson I learnt from this one-day trip in the underground of the city, is that any waste with a some value will be recycled. A full value chain will grow around valuable waste. If it’s still useable and if people can collect and process it for a small salary, then this waste will be recycled. A large amount of waste in developed countries is being shipped in China, India or other developing countries where people want a salary. They see the value of our waste and are willing to grasp it even though the working conditions are dangerous. As these countries are developing, they are less willing to manage rich-countries waste and less is being recycled. In the future, it will be important to increase the value of such waste so a recycling industry can flourish around it.
