2008

• 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.

Types of Waste for gasification

Hazardous Waste

Biodegradable organic

waste• Are very

polluting• High humidity

content, >70%

Non-Biodegradabl

e organic waste

Used tires

Municipal Solid Waste

A city of 1.000.000 in population can generate

between 300.000 and 500.000 Tm/year of

waste

2. The gasification

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 metalsReducing 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

Gasification advantages over other technologies

Incineration Biogas

Plasma Gasification

Pyrolysis

Gasification is the best technology for waste to energy from biomass and organic waste

Advantages of the gasification front of the incineration

• 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)

Advantages of the gasification front 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.

Advantages of the gasification front of the plasma gasification

The plasma gasification works at 6.000ºC

The “classic” gasification requires less investment and lower cost of operation and maintenance as well be getting more profitable.

Advantages of the gasification front of the pyrolysis

Pyrolysis is only recommended when the proportion of organic matter in the waste to value is

low.

Comparison with other gasification technologies

“Down draft”

• Only valid for very pure biomass.

• Pelletizing biomass is needed.

• Ash content is limited to ≤ 2,5%

“Fluidized bed”

• High cost of operation and maintenance.

• Pelletizing biomass is needed.

• Ash content is limited to ≤ 2,5%
