utilizing well produced
timber for industry and housing the world faces a bleak
environmental and social future.
Timber for use
in industry and housing has low energy requirements for production.
Timber causes relatively little environmental pollution during
production, and once produced, locks carbon out of the atmosphere
for the use life and the non-decay life of the product.
been proven as an effective housing and construction material over
thousands of years.
concerns relating to timber revolve around where and how the logs
are produced that the timber is manufactured from.
more timber, and or, a higher value of timber, and more utilitarian
products, Radial provides for
the necessity of cutting fewer trees to make the same volume or
value of timber. Higher value and volume of timber from a log
creates a higher value for the log which provides for the
opportunity to improve silvicultural practices relating to the
production of the logs in both natural and plantation grown forests.
of timber in the process of conversion of logs to sawn timber means
that there is less material available for housing and construction.
In an affluent society this can lead to effects
on house pricing and the forced usage of alternate materials which
may be more expensive, or that may cause other environmental
In energy and resource poor countries wastage
and inappropriate use of timber may mean that many people do not
have housing that could have housing.
Lower value for logs means that corners may have
to be cut and greater pressures in silvicultural and harvesting
practices. Higher value for logs can improve and encourage
plantation forestry and increase options for sustainable natural
Radial also offers high efficiency sawmilling
and best utilization of resource for small mills. There is no
requirement for specialist operator skill levels for quality timber
production. This means small plantation systems are more practical
as plantation viability is not based on the requirement of vast
tracts of land . Fuel and transport wastage can be reduced and
greater benefits returned to local communities.
Whatever the effect, cause or actuality of
climate change- Radial provides for logical solutions that affect a
range of the social, economic and environmental problems that
the world faces.
A summary of the reasons why only a percentage of a log ends up as sawn timber includes:
| Geometry losses
| Losses as sawdust.
| Growth ring misalignment.
| Removal of core-wood.
| Defect removal.
Typical effective recoveries in Australia of sawn timber from hardwood logs expressed as a percentage of initial log volume:
Large (old growth) logs carefully sawn - up to 60%
Large logs high speed sawing - 35% to 40%
Small logs quickly cut- 20%to 30%
|Eliminates or minimizes geometry losses.
and is efficient where wood quality is best.
|Eliminates growth ring misalignment.
|Enables efficient removal
or isolation of core wood.
|Enables efficient removal of defect.
|Produces recoveries of 40% to 80% across a range of log classes and sizes.
