Cradle-To-Cradle<br />
«We are not only responsible for our actions,<br />
but for the things we have failed to do.»<br />
Jean Baptiste Molière<br />
As a r<strong>en</strong>ewable raw material, wood is extremely<br />
important for our climate, our culture<br />
and the economy. Wood has virtually <strong>en</strong>dless<br />
growth pot<strong>en</strong>tial and therefore offers many<br />
ecological and economic advantages compared<br />
to fossil resources. Throughout their lifecycle,<br />
trees absorb carbon dioxide and water to g<strong>en</strong>erate<br />
oxyg<strong>en</strong> as part of photosynthesis, which<br />
is vital for most living things. Wh<strong>en</strong> a tree dies,<br />
it slowly decays and returns the carbon dioxide<br />
absorbed back into the atmosphere. The<br />
cycle th<strong>en</strong> starts again from the beginning.<br />
There is no cycle wh<strong>en</strong> using fossil fuels and<br />
ores for <strong>en</strong>ergy production and producing<br />
metals and plastics. The carbon dioxide accumulated<br />
over millions of years is released<br />
directly into the atmosphere all at once, dramatically<br />
speeding up climate change. The<br />
int<strong>en</strong>sifying gre<strong>en</strong>house effect contributes to<br />
changes in the climate. Thus, the longer the<br />
wood undergoes its natural cycle of materials<br />
while decaying and as a result of combustion,<br />
or the more frequ<strong>en</strong>tly it replaces fossil fuel materials,<br />
the more the carbon dioxide balance<br />
in our atmosphere improves.<br />
A particularly long life cycle and the associated<br />
storage of carbon is important for the <strong>en</strong>vironm<strong>en</strong>tal<br />
footprint of our products. Robinia wood<br />
inher<strong>en</strong>tly has excell<strong>en</strong>t physical properties<br />
for the construction of playground equipm<strong>en</strong>t<br />
(p.158). If cared for properly, our playground<br />
equipm<strong>en</strong>t can be used for around 30 years or<br />
more. The use of robinia wood in childr<strong>en</strong>’s<br />
playgrounds is sustainable, economical and<br />
innovative.
