The production of biofuel pellets has increased rapidly in Europe,
Northern America and China over the last 5 years, especially in
Sweden. In 2005, the total use of pellets in Swedenwas 1.5 million tons,
which corresponds to 7.1 TWh. The total market increased by 19% and
the sale of residential heating systems was enhanced by 33%.
Therefore, biofuel pellets play an important role in the shift towards
a more sustainable energy system in Sweden.
Sawdust of conifers as a by-product from saw mills is the most
commonly used biomaterial for pellet production in Sweden today.
Experiences from the biofuel pellet industry indicate that biomaterial
properties like tree species, origin of growth-place, storage time of
sawdust (maturity) and moisture content influence the pelletizing
properties and the pellet quality. However, only a few studies have
been reported so far [1–3] where biomaterial characteristics are
studied in combination with pelletizing parameters.
The aim of this work was therefore to evaluate the impact of the
origin of the biomaterial (species, growth-place latitude), and its pretreatment
(storage time) on the pelletizing properties and the pelletquality, and of their interactions in the production process by using a
pilot pellet press similar to an industrial production pellet press.
