1. Energy and Waste

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.

2. The gasification

Advantages of the gasification

Elimination of most of theincoming waste

• Elimination between 80% and 98% of thewaste depending of its nature.

• The resultant ash, minimum volume, are inert.

• Easy to recycle or treat. Possibility torecover heavy metals.

Reducing the emission of gases

• A 40% CO2 and 100% CH4 .

• High filtration efficiency: it avoids theemission of toxic gases.

• SO2, SO3 and NOx (promoters of acid rain)

• Dioxins and furans (carcinogens).

High efficiencyand profitability

• Lower cost per kWhgenerated

Abundance of fuel

• No dependence onforeign

• Usable in separateareas

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

• 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)

Advantages of the gasification

versus biodigestion

Biodigestionremoves 20% of theresidues, compared

to 90% of thegasification.

The digesters are useful with wet

waste.

They can be complementarytechnologies.

Advantages of the gasification

versus the plasma gasification

The plasma gasification works at 6.000ºC

The “classic” gasification requires lessinvestment and lower cost of operation and maintenance so it becomes more profitable.

Advantages of the gasification

versus the pyrolysis

Pyrolysis is only recommended when the

proportion of organic matter in the waste to

value is low.

3. GreenE plants

Applications of the gasification

Greene gasification plants adapt to any type of

organic solid fuel
