This paper sets out to describe the environmental impact assessment for wood charcoal briquettes
produced from eucalyptus wood in Brazil, with specific reference to those impacts associated with Global
Warming Potential. To achieve that objective, the work was undertaken in accordance with ISO 14040
"Environmental management e Life cycle assessment e Principles and framework" which describes
essential LCA characteristics and good practices. Charcoal briquettes are produced from two basic raw
materials, charcoal fines and starch. The fines result from the production of charcoal from sustainably
managed eucalyptus plantations. Starch is extracted from babaçu pulp in the Amazon region. Multi
eoutput processes were allocated based on income from the different by-products. The results showed
that more than 90% of incoming CO2 was due to biomass production for charcoal, and the remainder to
starch biomass production. Based on Brazilian data, as well as information provided by the GaBi4.3
database, it turned out that supplying the energy content of 1 kg of briquettes resulted in the sequestration
of 3.9690 kg of CO2, i.e. around 4 kg of CO2 per kg of briquettes produced. CO2 emissions
throughout the briquette production process are totally compensated for by the environmental quality of
the raw materials used.
