Introduction
Solid Waste Generated in a day?
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.

Methods of Waste Treatment
Methods of Waste Treatment:
Composting
Incineration
Recycling
Biological Reprocessing

Focus Questions
GHG emissions from solid waste generated in some major cities.
What impacts can different practices of solid waste management make on these
emissions
What contributions can individuals make towards solid waste reduction
Solid waste is going to increase with modern lifestyles, incomes per capita etc.
any innovative proposals to reduce waste generation?
Solid Waste is a resource and can be used to generate revenue. Your comments
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
In Conclusion
Improved waste management practices and their better knowledge leads to:
A better Environment
Cleaner and greener Planet
Less GHGs to worry about !!
