1. About the firm

1.1 Who are we?

GreenE designs, builds, turns on and manages

turnkey, biomass and waste to energy gasification

plants with home technology.

1.2 Our value proposition

Waste Disposal - The organic waste is eliminated in more than 80%, leaving only inert waste (ash).

Energy Generation - Syngas is transformed in electric and thermal energy.

Profitability - Maximum efficiency of the process. - Minimum investment per MW installed. - Profitable plants starting from 0.5 MW.

Experience

- Development team, formed by chemist and engineers, has been working on the process for the last eight years.

Services

- Full range of services to ensure the implementation and the profitable operation of the plant.

1.3 Products and services

-Reports for Industry and Energy projects.

-Environmental impact assessment.

-Subsidies application assistance.

-CO2 emission bonds management.

- Financial management Staff training.

- Plants operation and maintenance.

Services

-Technical and economic feasibility studies.

2. About gasification

2.1 Gasification applications

GreenE gasification plants can be adapted to any kind of solid

organic combustible:

Forest and agricultural biomass

Energy crop

Coal

2.2 Advantages of gasification over

other technologies

We bet on gasification as the best way to valuate

biomass and organic waste

Incineration Biogas

Plasma Gasification Pyrolysis

2.2 Advantages of gasification over

other technologies

Advantages over Incineration

• The gasification electric performance is 32% against

the 22% of incineration (Rankine Cycle). • 40% less of CO2 generated. • The gasification hazardous emission values such as

dioxins and furans are 1.000 times lesser than

incineration’s

• Gasification allows creating much smaller plants

(from 0.5 MW)

2.2 Advantages of gasification over

other technologies

Advantages over Biogas

• Biogas residues are about 80% whereas gasification residues

are about 20%

• They can be complementary technologies.

2.2 Advantages of gasification over

other technologies

Advantages over Plasma Gasification

• Plain gasification is cheaper in investment, operation and maintenance. Plasma gasification

works at 6,000 ºC.

2.2 Advantages of gasification over

other technologies

Advantages

over

Pyrolysis

Gasification is

preferable when

there is a high

proportion of

organic material in the solid

organic

combustible.

2.3 Advantages of gasification

Waste disposal Energy generation

Incoming waste is mostly

eliminated

• Resulting ashes are inert and minimum. • Easy to recycle. Possibility to recover heavy metals.

Totally clean and

usable generated

Synthesis gas.

High energetic

efficiency

Greenhouse gas emissions

reduction

• Up to 40 % of CO2 and 100% of CH4 reduction. • Filters effectively: No toxic gas emissions • SO2, SO3 and NOx (acid rain factors) • Dioxins and furans (carcinogenic agents)

Dependence on

fuel supply highly

reduced.

Opens possibilities

to electric supply

in isolated areas

High profitability
