Outline

Brazilian Ethanol Program

Ethanol Fuel (Social and Environmental Sustainability)

Replication of Brazilian Ethanol Program – Possible or not ?

Some Myths about Ethanol

1. Brazilian experience is unique; 2. incompatible with existing fleets; 3. low energy balances of biofuels;4. high pollutant emissions; 5. competition with food for land,

unsustainable practices, deforestation;6. only subsidized production is possible; 7. energy efficiency alone would preserve

oil resources and fulfill Kyoto targets.

The Brazilian Alcohol Program

The world largest commercial program on biomass 916 billion liters produced in 2005 – 2,5 billion liters exported)

Decision (1975) from Brazilian Federal Government to produce ethanol in addition to sugar (from sugarcane): objective of reducing petroleum imports (High prices).

High-octane fuel in vehicles, replacing lead and/or MTBE.

4,000,000 cars running on pure (hydrated) ethanol in Brazil

1,800,000 flex-fuel vehicles (both ethanol and gasoline, any blend)

all gasoline blended with (anhydrous) ethanol: 20 to 25% of ethanol in volume basis – gasohol

Nowadays - economically competitive to gasoline

Ethanol Production Costs (Brazil)

Production costs: US$0.18–0.25 per liter of gasoline-equivalent: – average export price of ethanol (2001-2003): US$ 0.23 per liter

Initial investment for new plants: US$ 60 million (2005 prices)– 40 new plants in São Paulo State; 100 in Brazil– Average processing capacity: 2.16 million tonnes of sugarcane

per year – average yield 79.39 liters of anhydrous ethanol equivalent (82.86

liters of hydrous) per tonne of sugarcane (Sao Paulo = 100-110 liters/ha)

– average price paid per tonne of sugarcane is US$11.4 (UNICA, 2005)

– plant lifetime of 25 years – feedstock cost of US$ 0.143 per liter of ethanol – investment cost around US$ 0.017 per liter of ethanol.

WHY BRAZILIAN ETHANOL IS COMPETITIVE?

– High agricultural/industrial yields efficient technologies 150 different varieties of sugarcane for

different types of soil

– Use of renewable energy source in the process (only sugarcane bagasse for cogeneration)

– Favorable energy balance 8-10:1

Sugarcane Expansion and Land Use in Sao Paulo State

2005 São Paulo State:

– Total territory: 24,800,000 ha– Used: 22,000,000 ha (cattle, agriculture, native forests

and reforestation)

Cattle (2005): 10,000,000 ha

Orange (2005): 672,000 ha

Sugarcane: 3,700,000 ha(5.5 billion liters of ethanol and 17

million tones of sugar)

Existing Environmental Legislation for Land Use – controls the use of Native Forest Land and Riparian Forests

Trend to more intensive cattle-breeding

Control and Enforcement of Environmental Impacts on Sugarcane

Ethanol Production

Legislation improved and enforced specially in the State of São Paulo (60% of all Brazilian sugarcane mills);

Discharge of effluents with high organic loads replaced by controlled fertirrigation practices (CETESB);

Harvest burning practices are being phased-out, through a strict legal enforcement;

Land use strictly controlled: preserving riparian forests and other natural ecosystems and avoiding deforestation;

Industrial sugarcane and ethanol plants have their atmospheric emissions controlled;

Spill offs and other accidents are rare and of low impact;

Social Aspects Job creation (700,000 jobs in Brazil

manly in rural areas) Legislation – social/labor issues

– For example: Forbidden manual harvesting of green sugarcane

Payments for rural workers on sugarcane crops are higher than other sectors

Perspectives for the Replication of Brazilian Ethanol Program in Other

Developing Countries

Feasibility studies – production costs? Technological aspects:

– Existing technology for alcohol production: efficient and commercially available (Brazil).

– Cogeneration process from bagasse efficient systems commercially available (Mauritius/Brazil).

Local capacity building + infrastructure Adequate policies (ex. Mandatory blend like in

Brazil and Malawi) Environmental aspects – sustainability is possible! Opportunities from the Clean Development

Mechanism good option for developed countries, collaborating for the sustainable development of poor countries.

Biofuels, developed and developing countries

Win-win situation for all !!

Thanks!

Obrigada!
