Properties of the continuous MWP plant

• Totally closed system
• No air or oxygen added minimum gas volumes
  generated high calorific value on gases
• Low thermal masses of the reactor give short
  start and shut down times
• Precise temperature control- Low carry over of
  pollutants- Facilitates better product control
• Small plants can be profitable
• Electric input 5 25 of feedstock energy

Why MWP? Conclusion

• Powerful tool in concentration of hazardous
  components in biomass and waste streams
• Waste reduction and in-process separation
• Conversion of biomass and bio wastes for bio
  fuels, energy and bio chemicals
• Attractive tool in education and international
  collaboration
• Development of new technology industrialisation
