COMPARAÇÃO DO IMPACTO AMBIENTAL DE CAPA DE LAPTOP UTILIZANDO A AVALIAÇÃO DO CICLO DE VIDA
Bibliographic record
Abstract
O presente artigo objetivou comparar o impacto ambiental de uma capa de laptop, produzida parcialmente com materiais reciclados, por integrantes de projetos sociais da Fundação de Ação Social da Prefeitura Municipal de Curitiba (FAS), com outras duas capas de laptop comerciais (corino e neoprene), através da utilização da metodologia de avaliação do ciclo de vida de produtos. Para o desenvolvimento da ACV foram adotadas as recomendações das normas ISO 14040. Os dados foram trabalhados no software SimaPro v. 8.0.5, com modelagem em relação aos impactos ambientais. Foi utilizada a base de dados do inventário Ecoinvent v.3, para definição do inventário do ciclo de vida do produto, e o método de avaliação IMPACT 2002+ para identificação dos impactos ambientais. Após aplicação da metodologia ACV concluiu-se que as capas de laptop que não utilizavam matéria-prima reciclada geraram menor impacto ambiental.

How this classification was reachedexpand
Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
