Life cycle assessment of offset paper production in Brazil: hotspots and cleaner production alternatives

“…For the life cycle inventory (LCI) phase, dataset inventories of the production of eucalyptus wood (forest production subsystem) and offset paper (industrial production subsystem) were extracted from two Brazilian LCA studies, one by Silva et al (2013c) and the other by Galdiano (2006). Silva et al (2013c) studied particleboard manufacturing in Brazil between 2010 and 2012, providing LCIs for forest and industrial subsystems based on primary and secondary data collected from 57.0% of the Brazilian manufacturers.…”

“…In this paper, only the LCI for forest production was adopted, and it was assumed that the wood is transported by truck for a distance of 80 km from the forest to the manufacturing plant. With regard to forestry inventory, Silva et al (2013c) provided a dataset for an area of 0.005 ha cultivated wood; therefore, all the flows were upgraded to reflect 0.025 ha because, according to Galdiano (2006), this is the area size required to supply wood to produce 1 ton of offset paper. Galdiano (2006) studied the LCI of offset paper in Brazil at five of the country's main paper manufacturers in 1998e2006.…”

Galdiano (2006) studied the LCI of offset paper in Brazil at five of the country's main paper manufacturers in 1998e2006. The result of his study was a consolidated inventory of the environmental aspects involved in the production of wood, pulp extraction, industrial offset paper manufacturing, and other associated subsystems under typical technological conditions in the country.…”

“…Only one Brazilian offset paper life cycle inventory (LCI) analysis by Galdiano (2006) was found. However, the author did not evaluate the environmental life cycle impacts, so no hotspots were identified and the study objectives did not include proposals for environmental improvements.…”

Avaliação do ciclo de vida da produção do painel de madeira MDP no Brasil

“…As práticas comuns nos viveiros de mudas incluem a melhoria genética, o controle de pragas e doenças, adição de nutrientes e irrigação (GALDIANO, 2006). As atividades específicas dentro do viveiro dependem do sistema de produção de mudas adotado.…”
