  1. A universidade e o trilema alimento/energia/meio ambiente: desafios tecnológicos e possíveis soluções The university and the trilema food/energy/environment: technological challenges and possible solutions Prof. Dr. Paulo A. Z. Suarez Laboratorio de Materiais e Combustíveis Instituto de Química – Universidade de Brasília

  2. The trilema food/energy/environment: • Save natural resources: diminish consumption, use wastes and recycling materials; • Social and environmental responsibility of a university: developing innovative technologies suitable to produce biofuels from residual materials, both produced by urbane or agribusiness activities, and from alternatives fat and oil sources that do not compete with food production and address the actual energy, environmental and food supply crisis.

  3. Biodiesel from Low-Price Feed Stocks • Macauba: palm-tree native in the Brazilian Savannah region • Millions of acres used to grow cattle have native or reforested Macauba • Production up to 5,000 liters of low grade oil (acidity about 65%) per hectare

  4. Biodiesel from Low-Price Feedstocks

  5. a Molar ratio of macauba substrate:water:catalyst of 1:50:0.14, at 200 °C, 2h; bMolar ratio of macauba substrate:methanol:catalyst of 1:32:0.14, at 160 °C, 2h; c Molar ratio of macauba substrate:methanol:catalyst of 1:32:0.14 at 80 °C, 3h; d Molar ratio of macauba substrate:methanol:catalyst of 1:32:0.14 at 200 °C, 2h.

  6. Biodiesel production: PilotPlant Fluxes: methanol 89 g/h; Oil 68 g/h. Catalyst fixed bed mass: 2,65 kg. Average reaction yield: 77.0 ± 3.8 % at 100 °C.

  7. Agro-Industrial Residues as Low-Price Feedstock for Diesel-Like Fuel Production by Thermal Cracking

  8. Yield for the different products after the pyrolysis of: (1) Soybean Soap Stock; (2) Beef tallow; (3) Poultry industrial waste.

  9. Yield for the different products after the pyrolysis of: (1) Soybean Soap Stock; (2) Beef tallow; (3) Poultry industrial waste.

  10. Pilot plant unit:

  11. Final remarks: • It is difficult to think we will find one unique solution to address the actual energy, environmental and food supply crisis; • Social and environmental responsibility of a university makes mandatory to develop innovative technologies using local solutions; • It is possible to produce biofuels without competing with food production.
