Small wood set for big green role

MATERIALS

A PROJECT to develop structural grade timber from small pieces of wood could cut waste.

Researcher BRE is investigating methods that allow thin pieces of wood to be bonded together and used as structural members.

Normally, small diameter hardwoods are shunned by the construction industry and sent for use as firewood or turned into paper pulp.

But a combination of increased timber prices and the development of a new sawing technique could make the production of beams using smaller diameters bonded together viable.

The technique involves cutting small diameter sections into quarters and bonding them into square sectioned beams.
