Waste to Energy Technologies

• Incineration

• RDF (Refuse Derived Fuel)

• MBT (Mechanical Biological Treatment)

• Gasification & Plasmification

• AD (Anaerobic Digestion)

11

Organic Processes

• Aerobic

– Compost

• Anaerobic

– Methane

– Digestate

12

How to Choose?

• Many Factors:

– Diversion Mandate

– End Markets

– Tipping Fees

– Cost of Energy/Thermal Customer

– Regulatory/Environmental Issues

– Bans

– Public Issues
