According to the World Bank, in 2016 the world’s cities generated 2.01 billion tonnes of solid waste, which equated roughly to 0.74 kilograms per person per day. This demonstrates a serious concern.
The UN has estimated that the global population will near 11.3 billion by 2060, with Africa expected to experience just as much exponential growth (2.5 billion by 2050), which will represent about 26% of the world’s total population.
However, it also alludes to a very serious challenge that threatens the future resilience and sustainability of cities, if we don’t change our attitudes to what we consider resources versus waste.
Globally, however, there has been strong intervention, to change both consumer attitudes as well as a business practice – when it comes to waste.
