WORLD SCENARIO OF WASTE

image

As per report by World Bank, waste generation was estimated to be 2.24 billion tonnes i.e. per person waste generation is about 0.79 kilograms per person per day. Which makes todays waste generation considering the population of the world to be 8 billion to be 6320 thousand MTs of waste per day.

Due to rapid population growth and urbanisation, the waste generation is also rising rapidly. Annual waste generation is expected to increase by 73% from 2020 levels to 3.88 billion tonnes in 2050.

The volume and complexity of waste associated with the modern economy is posing a serious risk to ecosystems and human health. Solid waste is contributing about 5 percent of global greenhouse gas emissions.
