This document discusses waste to energy gasification technology. It describes how gasification can efficiently convert biomass and waste into syngas while reducing emissions. The document outlines the various types of waste that can be gasified, as well as the advantages of gasification compared to other waste treatment technologies like incineration and biodigestion. It then profiles GreenE, a company that designs and builds gasification plants using a proprietary rotary reactor system to process organic waste and generate electricity.

4. Electricity needs and sources
• Energy needs are growing worlwide.
• The dependence on fossil fuels will remain high.
• It is anticipated a growing demand for renewable energy, particulary
electricity generators.
Additional Energy Efficiency Scenario: Evolution of installed capacity as energy sources.

8. 2. The gasification

9. Advantages of the gasification
Elimination of most of the
incoming waste
• Elimination between 80% and 98% of the
waste depending of its nature.
• The resultant ash, minimum volume, are
inert.
• Easy to recycle or treat. Possibility to
recover heavy metals.
Reducing the emission of
gases
• A 40% CO2 and 100% CH4 .
• High filtration efficiency: it avoids the
emission of toxic gases.
• SO2, SO3 and NOx (promoters of acid rain)
• Dioxins and furans (carcinogens).
High efficiency
and profitability
• Lower cost per kWh
generated
Abundance of fuel
• No dependence on
foreign
• Usable in separate
areas
To eliminate waste To generate electricity

10. Gasification advantages over other
technologies
Incineration Biogas
Plasma
Gasification
Pyrolysis
Gasification is the best technology for waste to energy from biomass and organic waste

11. Advantages of the gasification
front of the incineration
• It uses only 25-30% of the oxygen required for
complete combustion of organic matter,
avoiding emissions of CO2 to the atmosphere
(environmental benefits).
• In gasification, emissions of hazardous
compounds (dioxins and furans) are 1.000
items smaller.
• The energy efficiency of the gasification is
higher than incineration, getting electricity and
heat.
• It generates 40% of CO2 less per kWh
produced.
• Gasification allows smaller plants
(from 0,5 MW)

12. Advantages of the gasification
versus biodigestion
Biodigestion
removes 20% of the
residues, compared
to 90% of the
gasification.
The digesters are
useful with wet
waste.
They can be
complementary
technologies.

13. Advantages of the gasification
versus the plasma gasification
The plasma gasification works at 6.000ºC
The “classic” gasification requires less
investment and lower cost of operation and
maintenance so it becomes more profitable.

14. Advantages of the gasification
versus the pyrolysis
Pyrolysis is only recommended when the
proportion of organic matter in the waste to
value is low.

15. 3. GreenE plants
