RESUMO:

The model of preparation of the area with cutting and grinding, from the TIPITAMBA project, is considered sustainable and, therefore, it is considered an alternative to the cutting and burning system, however, the lack of firewood supply is indicated as a disadvantage to be solved. The objective of this research was to evaluate the socioeconomic profile of family farmers in the Northeast and their demand for alternative sources of biofuels, as well as to evaluate the energy potential of capoeira grind`s biomass in different types of management for alternative source for domestic use in the Northeast from Pará. To do so, took place a field survey to find out and evaluate the perception of family farmers, their production system, income, as well as the demand, estimates and difficulties that farmers use in relation to firewood, in addition to data collection to assess the potential of capoeira grind`s biomass as an energy source. Several were used tools were used, such as interviews, direct observation, in addition to laboratory analyzes of physical, chemical and energetic characteristics of biomass. In the biomass evaluation, the procedures related to the type of grind`s capoeira were adopted, with one and two grinding with the Tritucap. That delimitation the removal of biomass for energy purposes, with the adoption of
three types of screens, 35mm, 55mm and 75mm mesh. The design used in the five-year capoeira experimental area was the 2x3 factorial DBC, with four replications. The results demonstrated that by family farmers in the municipality of Igarapé-Açu, there are demanding by an alternative biofuel, as they present mainly the difficulties of acquiring firewood, collected mainly in the capoeira area from five to ten years of age and with area preparation, and with a demand of 0.50 t or 2.68 of firewood for each 1 t of flour produced. The five-year-old crushed capoeira biomass shows the indexes of bioenergetics qualities the following results found for biomass traditionally used as biofuel, having sufficient energy potential for a direct combustion for prepared for the cassava flour of the familiar individuals, even using only 25 Total% of grind´s biomass, with the adoption of the largest opening sieve (75mm) and with only one grinding.
