Treatment options:
- Landfilling
- Incineration
- Mechanical-biological treatment (MBT)
GHG emissions from rMSW management
rMSW = what remains after separate collection
- Food- Yard- Wood- Paper
- Textiles- Nappies- Residuals
- Plastics- Metals- Inerts

Direct emissions- CH4 Biodegradable materials under anaerobic conditions- CO2 Combustion of fossil carbon
Indirect emissions- Energy demand GHG emissions from energy generation
Avoided burdens- Materials Substitution of primary raw materials- Energy recovery Substitution of GHG emissions from energy generation
Origin of GHG emissions
