Necessities: Conclusion Although the forecast of a significant increase Cooperation between the in the number of sugar/alcohol industries in the central government and State of Mato Grosso do Sul, the biomass local government for the cogeneration with power export is not a incentive to the guaranteed procedure. cogeneration. Bigger balance between the Biomass and other sources in the incentive mechanisms. Bigger weight of the ambient advantages in the creation of regulations Laws. 20
