Abstract
A method of forming a structural member from hemp hurd and the structural member produced which is substantially free of hemp bats fibers is made by providing hemp stalks which have been decorticated and hurd material is divided into hurd strands which are then mixed with a binder and then pressed into a structural member. The hemp hurd strands can be mixed with wood strands to form wood/hurd structural members.

- (b) splitting the hurds longitudinally to produce hurd strands;
- (c) adding binder to the hurds;
- (d) orienting a majority of the hurd strands such that the hurd fibres are substantially parallel in the structural member;
- and
- (d) pressing the hurds into a desired shape and allowing the binder to set.
