Global Status of MSW Generation & Collection

Globally, city residents (3 billion people) and commercial entities discard 1.3 billion

tones (metric tons) of MSW per year, this equates to a daily generation rate of 3.6

million tones.

The average daily per capita MSW generation rate worldwide is 1.2 kilograms (kg).

Cities in low-income countries tend to have collection rates below 50% of waste

generation, while collection rates above 90% are common in cities in high-income

countries.

Solid Waste and GHG Emissions

Waste emissions includes GHG emissions resulting from waste management activities

The manufacture, distribution, and use of products—as well as management of the resulting waste—all result in emissions of greenhouse gases that affect the Earth’s climate.

Exercise

Use WARM (Waste Reduction Model) software to determine differences in

GHG emissions when different waste management practices are followed

Waste generated and associated GHG emissions in major cities of the world

and what practices adopted

What recommendations can be made to improve waste management

practices in your country

What you can do..

Reduce Your Packaging

Try to bulk buy wherever possible

Select Reusable Products

Reuse Products: Recycle everything while you can

Buy Products Made From Recycled Material

Compost

Reduce Toxicity

Use Durable Products
