Cascading use of woody biomass is getting increasing
attention in current European discussions to ensure the
sustainable and resource-efficient use of wood in future
bioeconomy. So far however, there is no exact agreement
on what is meant by "cascading". This report shortly
summarizes several definitions on cascading use of
biomass and discusses their differences.
In addition, the wood flows in Finland on the year 2013
are presented, as well as examples of wood flows in
selected other EU countries. Based on the comparison, the
differences between the countries are discussed. Finland
exports most of the products processed from woody
biomass. Thus, the cascading cycles often take place
outside Finland. Therefore the role of a wood producing
country (e.g. Finland), supplying virgin fibre, differs
significantly from the consumer countries (e.g. Germany
and Holland) with more recycling, which creates
challenges for creation of common cascading concept .
Cascading should be considered from the perspective of
the whole wood using cycle, recognising the regional
differences in wood flows, when discussing about the
cascading principles. Furthermore, the overall efficiency
of recycling needs to be taken into account.
