Maintaining the delivery of basic urban service—including waste collection and management—is becoming a growing challenge to cities grappling with the fallout from COVID-19. Every year the world generates over 2 billion metric tons of municipal solid waste. The World Bank estimates that by 2050 annual waste generation will increase by 70 percent—to 3.4 billion metric tons. In low-income countries, the volume of  waste is expected to triple by 2050, particularly in sub-Saharan Africa.
