1 BIOFUEL ETHANOL: AN ANALYSIS OF THE ENVIRONMENTAL STATE OF LAW IN THE RISK SOCIETY Authors: José Rubens Morato Leite, Délton Winter de Carvalho, Matheus Almeida Caetano, Silvana do Prado Brouwers and Maria Leonor Paes Cavalcanti Ferreira

2 BIOFUEL ETHANOL: AN ANALYSIS OF THE ENVIRONMENTAL STATE OF LAW IN THE RISK SOCIETY  Different topics;  Consequences.

3 POSITIVE CONSEQUENCES OF SUGARCANE ETHANOL - Reduction of the Greenhouse Gases; - Assimilation of CO2 by the cane; - Brazilian sugarcane ethanol is the most efficient biofuel in energy production;

4 POSITIVE CONSEQUENCES OF SUGARCANE ETHANOL: - employments; - “energetic emancipation”.

5 NEGATIVE POINTS OF SUGARCANE ETHANOL: Monoculture agricultural; Devastation of rainforests; Loss of biodiversity;

6 NEGATIVE POINTS OF SUGARCANE ETHANOL: Sugarcane burning Air pollution - Put food prices on the increase.

7 BIOFUEL Biofuel is any liquid, gaseous, or solid fuel produced from plant or animal organic matter. Soybean oil, alcohol from fermented sugar, wood as fuel, etc

8 FIRST GENERATION BIOFUELS Use crops as food stocks; Low technological complexity

9 FIRST GENERATION BIOFUELS Examples: biogas, biodiesel (soybean, sunflower and rapeseed), ethanol (corn, sugarcane, sugar beet and wheat) and vegetable oil.

10 SECOND GENERATION BIOFUELS  Cellulosic biomass;  Advanced technology;  Examples: biohydrogen, biogas, bioethanol and biofuel synthetic.

11 THIRD GENERATION BIOFUELS Seaweed as raw material  ability to fix nitrogen from the atmosphere  greater efficiency photosynthetic  extremely small

12 THIRD GENERATION BIOFUELS In Brazil, since 2006  research to produce biodiesel from microalgae  CHALLENGE: very expensive and consumes much energy.

13 Environmental State of Law  Environmental problems are synergic and very complex.  Mechanisms of the Environmental Rule of Law:  BAT

14 Best available technology Machines to cut sugarcane, Cellulosic ethanol production from biomass-waste; Non-use of pesticides.

15 SOCIAL SEAL program with social criteria (tax incentives) reduce regional disparities

16 CHALLENGES  INTEGRATED MANAGEMENT  ecological economic zoning  planting areas on too dry or degraded lands for food production and only with native plants

17 CHALLENGES  decentralization of ethanol production  ethanol production by family farmers and the possibility of selling it to large companies.

18 INTEGRATED MANAGEMENT  Example: energetic self-sufficiency of some Brazilian plants, existing in some cases even a surplus, sold to electric distribution companies.  Second generation ethanol production must increase, using garbage and waste as raw material.

19 CONCLUSION  It’s necessary a policy of biofuels with a integrated system of food and bioenergy production, with a link among all environmental public agents and with a condition in environmental that allows the good use of biomass residues, to get a best environmental protection.
