Entre mai 2006 et avril 2007, Native a effectue un bilan des émissions de gaz a effet de serre (GES) de la filière biologique de l'Usine de Sao Francisco (UFRA). Cette évaluation a été réalisée selon le protocole GHG - modèle international pour mesurer les émissions - en considérant les effets de la culture de la canne et la production de sucre et d'alcool a l'usine. Compte-tenu qu'une partie de cette production est destinée a l'exportation, l'énergie nécessaire pour le transport de ces marchandises vers leur destination finale (USA, Europe, Japon) a également été prise en compte.

Les quantités d'émissions trouvées pour UFRA sont plus basses que les niveaux moyens d'émissions de l'industrie de la canne a sucre, du fait de ses méthodes de production biologiques. Comparée a la production de sucre a partir de la betterave en Europe ou au Japon, ou encore a la production de sucre a partir de la betterave ou du mais aux Etats-Unis, les écarts sont encore plus nets, car ces méthodes de production fonctionnent a partir d'énergies fossiles alors que UFRA utilise de l'énergie a base de bagasse de canne a sucre.

Energy Self-Sufficiency

The São Francisco Sugarmill is self-sufficient in power production from burning sugarcane bagasse. High efficiency boilers ensure clean, sulfur-emission free biomass burning. The boilers produce steam, converted to thermal, mechanical, and electrical energies. The steam moves a turbo generator that meets the Plant's electricity needs.

In June 1987, the São Francisco Sugarmill, for the first time in Brazil, sold a small surplus of electricity to the local distribution network, commencing the supply of power derived from sugarcane bagasse to the population.

In 2002, with the expansion of the Santo Antônio Sugarmill’s Power Plant, Bioenergia reached an electricity production capacity of 140 GWh/year, of which 53 GWh/year are consumed in the sugarcane milling process, and 87 GWh/year marketed.

From 2010, with the expansions made to São Francisco Sugramill’s Power Plant's capacity, Bioenergia boosted its production capacity to 218 GWh/year and went on to market 146 GWh/year. The electricity Bioenergia sales suffice to meet the needs of a city with 476,000 inhabitants.

The expansion of the cogeneration model to other plants could mitigate the risk of a blackout in power supply in the northeastern region of the State of São Paulo. The sugarcane harvest takes place between May and November, in the dry season, when hydroelectric reservoir levels are low.

In addition to this strategic advantage, the electric power cogeneration system using sugarcane bagasse burning (fuel derived from biomass) is neutral in greenhouse gas emissions, as opposed to power generation in thermal power plants fired by fossil fuels, which are high in emissions. Balbo Group's cogeneration project, reviewed and approved under the Kyoto Protocol's Clean Development Mechanism, has led to the trading of carbon credit equivalent to 143,000 tonnes in emissions avoided between 2002 and 2010.

The sugarcane industry has great potential in this area, in actions such as:

01. Substitution of conventional cultivation for organic farming;

02. Establishment of islands of biodiversity in the sugarcane fields;

03. Production of ethanol (non-fossil origin) and its products;

04. Cogeneration of electric energy made from sugarcane bagasse;

05. Substitution of beet sugar for sugarcane sugar.
