 RESUMO: Os objetivos do trabalho foram: caracterizar a fumicultura na região sul do Brasil; verificar o consumo de biomassa na cura do tabaco; verificar a disponibilidade de resíduos do processamento mecânico da madeira como alternativa de fornecimento de biomassa para fins energéticos. O tabaco, mesmo ocupando 18% da área das propriedades, foi responsável por, em média, 53% da renda do produtor na safra 2017/2018. Observou-se um consumo maior de lenha em comparação à serragem, para cada kg de tabaco curado, 2,75 e 2,69 kg, respectivamente. Com relação à disponibilidade de resíduos florestais, foi demonstrado que existe um volume significativo para aproveitamento energético, e ainda ocioso, principalmente os oriundos do processamento de madeira. O uso da serragem em substituição à lenha foi tecnicamente viável e elevaria o nível de comprometimento do setor com a sustentabilidade da atividade fumageira.

 FOREST RESIDUES ENERGY USE AS AN ALTERNATIVE TO FIREWOOD IN TOBACCO FARMING OF SOUTHERN BRAZIL
 
 ABSTRACT: The objective was to characterize the tobacco culture in the southern states of Brazil also analyze the consumption of biomass in tobacco curing, and access availability of mechanical processing wood residues as an alternative supply of biomass for energy purposes. Tobacco, despite occupying only 18% of the properties area, it accounted for an average 53% of the farmers income in 2017/2018 crop. There was also a higher consumption of firewood compared to sawdust for each kg of cured tobacco, 2.75 and 2.69 kg, respectively. Regarding the forest residues availability, there is a significant amount of forest residues for energy recovery level that still idle, especially those from the wood processing. The sawdust usage to replace firewood was technically practicable and would raise the level of commitment of tobacco sector bringing more sustainability to this activity.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
