NEED FOR INNOVATIVE BUILDING SOLUTIONS

MOVING FORWARD
By 2050, two-thirds of the world’s population will live in urban areas. At the same time, the urgent
need for housing and supportive infrastructure continues to surge at record rates. One important
part of the solution?
Converting the built environment from a carbon source to a carbon sink.

Construction sector
contributes to
40% to

emission.

Cement is the source of about 8% of the

The global iron and steel industry accounts
for approximately 5% of total
global CO2emissions.

Forces in an earthquake are proportional to the structure’s weight and wood is substantially
lighter than other major building materials. The fact that it is durable and adaptable also creates
opportunities for renovation, re-use and recycling.

Moisture Control
Wood is a hygroscopic material, which means it naturally absorbs and
releases water to balance its internal moisture content with the
surrounding environment.

Acetylation’s advantages
A process developed more than 80 years ago,
acetylation modifies the wood at a molecular level to
alter its reaction with water. This permanently alters
wood’s propensity to absorb and release water—the
quality that makes it swell and shrink. Taking the place
of those water-absorbing free hydroxyls are stable
acetyl groups that do not bond with water. Wood
naturally contains acetyl molecules; the nontoxic
acetylation process simply increases their levels so the
wood no longer responds as usual to moisture. This
reduces its tendency to shrink and swell by more than
70 per cent.
accoya_process-en
This means the manufacturing process adds nothing
into the wood that does not already naturally occur
within in. The end product, acetylated wood, does not
add toxins to the environment.
The process also renders the wood inedible to insects
and parasites like fungi and far more resistant to rot and
decay than unmodified wood. The result is a durable,
dimensionally stable product with the natural beauty of
wood.
