N2 - Life cycle methodology was developed and applied to
assess environmental burdens and impacts of the logging
and sawmill residues throughout the whole fuel chain from
the forestry to energy production. Environmental aspects
of the sawmill residue chains and the terrain and the
roadside chipping chains for logging residues, including
both the fresh and the dry chipping options, were
analysed for a variety of air emissions from the chipping
and the transportation machinery. The data for the energy
production was acquired with emission measurements and
the material balance calculations made for a energy
plant. Thus the study provided a good first stage
database for the life cycle assessments of wood based
energy. However, many important issues, such as the
processes and the time span of the forestry, nutrient
economy of the forests including the various options of
nutrient generation, recycling and compensating
fertilisation, soil emissions, carbon cycle, radiative
forcing, and biodiversity, were excluded from the agenda
of the study.
