  1. Municipal Waste as a Viable Fuel Dr Robert Eden Technical Director PT NOEI

  2. CONTENTS OF PRESENTATION • GALFAD - An Integrated Waste Disposal Concept • Anaerobic digestion • Landfill gas utilisation • Thermal waste treatment

  3. GALFAD GALFAD An integrated waste management system

  4. GALFAD GA – Gasification (pyrolysis) LF – LandFill gas AD – Anaerobic digestion

  5. MSW PATHWAY OPTIONS

  6. GALFAD • Separation • Wet- waste to anaerobic digestion • Dry-waste to pyrolysis • Bio-solids to compost • Biogas and syngas to electricity

  7. SEPARATION

  8. SEPARATION

  9. ANAEROBIC DIGESTION

  10. ANAEROBIC DIGESTION Anaerobic digestion is a biological process for converting organic materials into a combustible gas It normally takes place in a wet environment and in the absence of any air Organic materials are broken down to produce methane and carbon dioxide

  12. LANDFILL GAS UTILISATION Puchong LFS -Malaysia

  13. Landfill gas power station Xing Feng LFS - China

  14. Fuel skids

  15. PYROLYSIS / GASIFICATION

  16. PROCESS DESCRIPTION

  17.

  18. General layout of an MT2 unit Waste Heat Boiler Waste Feed Pyrolysis Tubes Emissions Abatement Thermal Oxidation Pyrolysis & Gasification

  19. ENVIRONMENTAL IMPACT Typical results for clinical, pharmaceutical and other wastes

  20. clinical waste dried sludge shredded tyres commercial waste refuse derived fuel (RDF) municipal solid waste (MSW) ACCEPTABLE WASTE TYPES

  21. Summary • Every site is unique • Of critical importance is the specific waste composition and in particular the moisture content • 100 tonnes per day of feedstock (typically 175 tonnes per day of waste) will generate 2.5 MW of power
