Around the world, waste generaon rates are rising. In 2016, the worlds' cies generated 2.01 billion tonnes of solid waste, amounng to a footprint of 0.74 kilograms per person per day. With rapid populaon growth and urbanizaon, annual waste generaon is expected to increase by 70% from 2016 levels to 3.40 billion tonnes in 2050. Compared to those in developed naons, residents in developing countries, especially the urban poor, are more severely impacted by unsustainably managed waste. In low-income countries, over 90% of waste is oen disposed in unregulated dumps or openly burned. These pracces create serious health, safety, and environmental consequences. Poorly managed waste serves as a breeding ground for disease vectors, contributes to global climate change through methane generaon, and can even promote urban violence.
