Wood logs are still the most important bioenergy source in Germany. None the less each year in
winter there is a lack of ovenready wood logs for domestic wood furnaces. This means that the
preparation of wood logs has to be improved by rationalisation of workflow. To do so there is a
need of getting scientific numbers of the preparation of splitted wood logs and further the storage
of wood logs. But there are no scientific numbers available yet. To receive these numbers this
study includes time studies of different existing workflows of harvesting and preparation of wood
logs with the energy input, trials of the different ways of storage, the determination of the dry
matter loss of wood logs while the storage, measurements of the work intensity while harvesting
and the preparation of woodlogs and the converting volumes. With these results one is able to
combine the numbers in order to get the economic evaluation of four paths with different ways of
the preparation of splitted wood logs.
