Global Waste Management Trends

Main Messages

• Waste generation is anticipated to increase by 70% by 2050 with Sub-Saharan Africa and South Asia growing the fastest (35% of global waste by 2050)

• One-quarter of global plastic waste is coming from East Asia and the Pacific with ocean waste primarily coming from 5 countries in the region

• Nearly 50% of solid waste operations involve the private sector, nonprofits or civil society and there is further opportunity to engage

Waste is expected to increase by 70%

by 2050

2016: 2.01 billion tonnes

2050: 3.40 billion tonnes

NepalTreatment & Disposal

Solid waste management contributes to 5% of global emissions (excluding transportation)

2016: 1.6 billion tonnes CO2-equivalent GHG emissions

2050: 2.6 billion tonnes CO2-equivalent GHG emissions

17

The poor are most affected by inadequate waste management

18

30% of countries do not have any institutions or policies to

address waste

19

Waste is overwhelming a predominantly local government

responsibility

20

Local governments often lack funds, only covering ~50% of

investment costs for waste systems

Remainder comes mainly from the national government

and the private sector 21

>50% of services are operated by public entities & ~1/3 involve a public-

private partnership

22

In low-income countries waste

management consumes ~20%

of municipal budgets

High income countries: >$100/tonne

Lower-income countries: ~$35/tonne

23

Time for actionis now.

Major investment is needed

25

1) Focus on Sub-Saharan

Africa and South Asia

which account for nearly

half of the growth in waste

by 2050

2) Prioritize 5 countries in Asia

to address bulk of marine

litter problem

Engage the private sector

26

3) Adopt regulations and

incentives to attract

financing and the right

partners—private sector,

nonprofits, or civil society
