panel, the first ecological produced wood material made of saw dust
and wood flour
least 200 million cubic meter saw dust and wood flour per year are
to be obtained by sawing industrial rough timber. So far these by-products
could only be used for process heat. As a raw material for the paper
industry or for wood based panels like chipboards the fibers of
saw dust and wood flour are missing the needed strength.
swiss startup company innovation wood (iwood for short) is
founded on the idea of developing a marketable, new process for
the production of environmentally friendly and affordable panels
for the furniture and building industries. Panels and mouldings
are produced by firstly forming a dough made of sawdust, wood flour,
starch and water. That dough is foamed in the next step either mechanically
or by microorganisms (mainly yeast) very much like a bread dough.
The wood paste is then dried, resulting in a hard material (like
crackers or crispbread) with properties comparable to chipboard
and similar products.
iwood panels as a material weighs half as much as current
conventional materials (250 300 kg/m3) and can
easily be grinded, sawed, planed, drilled, screwed and glued with
