Annually, 13% of the waste generated by humans is recycled, but where does the remaining 87% go? The combination of different types of waste is gradually filling the Earth’s oceans and landfills, leading to a negative impact on wildlife, the natural environment and human health. Within the large amounts of solid waste produced in developed cities, used electronics are a clear example of how materials can be efficiently managed after their life cycle ends. Understanding the behavior of these materials and resources before, during and after their useful life cycle has guided the search for new solutions, such as the Cradle to Cradle (C2C) methodology.
