Sustainable development is development that meets the needs ofthe present without compromising the ability of future generationsto meet their own needs.
A sustainable material meets the needs of this generation, withoutcompromising the ability of the next generation to repurpose or recyclethat material to meet their own needs. Does your material cost less to produce than standard materails? Yes NO Does your material perfom on a scale that is Does your material out perform existing better than its percentage of existing materials marterials on a scale equal to its cost cost increase? Yes No Yes No

Oriented Strand Board OSB is an engineered wood product formed by layering strands (chips) of wood in specific orientations. Created in Canada in the late 1970s, OSB is a result of waffle board development. http://image.made-in-china.com/2f0j00HBvQptWavMzj/OSB- Board-1.jpg
Production Layers are laid down sequentially: longitudinal, transverse and longitudinal.Adhesive resin is sprayedwith a rotating disks. http://www.cambridge-biopolymers.com/images/OSB%20and%20resin.jpg http://upload.wikimedia.org/wikipedia/commons/7/71/OSB_production.jpg
Implementation Why to use OSB in construction? - No shrinkage - No design restrictions - Lower price - Expedited construction SustainabilityOSB recycles woodenproduction waste material:chips and other woodenparticles.
PLYWOOD and similars Plywood is a wood product which is made of layers parallel to each other with 0 or 90 degrees angle. It is possible to be covered by any other material. Photos by Deniz Löktas 2012

InnovationWood materials have been started to beconsidered as materials to make buildings withseismic strength.For this purpose, a 7 storey wooden buildingwas tested in Japan against earthquake, in2007 by Italian Professor Ario Ceccotti,University of Venice, Civil EngineeringDepartment.There are similar researches made in USA byNational Science Foundation, under the name Prof. Ario Ceccottiof NEESWood Project. www.dolomitipro.it/foto/anteprima/prof_ario_ceccotti_cnrivalsa,17.jpg
