The main goal of this study was to analyze the environmental profile of
MDF panel manufacturing in the Brazilian industry in terms of energy, emissions and
dependence on renewable sources. The study was conducted by using the methodology
of Life Cycle Assessment (LCA), specifically through the development of the first Life
Cycle Inventory (LCI) of MDF in a Brazilian industry. The life cycle inventory and the
production processes analysis were constructed using Umberto® v.5.6 software and
following the ISO 14040 series. The study covers the life cycle of MDF production from
gate-to-gate perspective, involving the on-site manufacturing system. The functional unit
was defined in 1 m³ of MDF. About 76% of energy required to produce MDF is thermal
(52.8% of thermal energy is required for the drying process of wood fiber). CO2 is a
major emission during the MDF production, where natural gas contributes to 96.7% of
total CO2 fossils. It was observed a low dependence of non-renewable source (19.2%)
compared with the literature.
