Why use strawboard instead of wood
Fire-Rated Door Core Particle Board with Mdi Glue


 

The question that many people ask is, "Why make particleboard out of straw?" The main reason is the availability of excess
straw, which is either baled or burned. Straw burning creates a health hazard to many people with respiratory problems.
The smoke has also contributed to higher rates of respiratory diseases and is generally harmful to the environment.

Depleting forests and the availability of wood chips for particleboard production due to the over-cutting of forests is another
factor that has reduced the amount of available timber. Governments are now more concerned than ever about regulating
the annual allowable cutting which takes place. Due to the depletion of the timber supply, the quantities of wood in the form
of sawdust and planer shavings have also been reduced. These products are the basic feedstock for wood-based
particleboard. As a result of the declining supply, prices of wood products and residue have increased.

Straw is a renewable resource. Unlike trees, which may take 20 years to grow to a size that is useful for timber production,
straw is produced each year with a new crop. Shortages of straw should be rare and very short term, until a new crop is
produced. Agrologists suggest that many farmers would be happy to give away or sell their straw for a minimum price because
there is usually much more straw than is required to maintain soil health.

Straw particleboard production is environmentally friendly. It uses an input that is often burned (which increases pollution) to
make a product that can replace wood-based products. By using more straw and fewer trees, it preserves the forests and the
 environment. This benefits wildlife, outdoorsmen, and general nature lovers. As well, the methylene-diphenyl-diisocyanate
(MDI) resin, the binding agent for strawboard is non-toxic and doesn't produce harmful emissions from the finished product.
