TIMBER ASSESSMENT TASK
By Ryan Bondfield 8IA2
WHERE DOES TIMBER COME FROM? Comes from any
type of tree Because some trees
are rarer than others this means that different timber types cost more
Pine trees are the most common timber type
Different types of timber floors
WHY IS PINE THE MOST COMMON? Pine is the most
common wood type because the tree is:
Quick to grow Doesn’t need
much space Easy to cut And easy to cure
Pine tree plantation
HOW TREES TURN INTO TIMBER After a tree is chopped
down, it is sent to a mill and cut into timber
From there it is preserved.
To be preserved it is treated with chemicals that go into the fibres of the wood.
WHAT IS TIMBER USED FOR? Anything that is
made of woo is a product of timber.
This includes: Paper Furniture Wooden floors Housing equipment Rafts and boats
ETHICAL VIEWS TO THE USE OF WOOD- PROS
Out of most, if not all products, wood is the most sustainable and natural material on the market today
it also does not hurt the environment as much as the other products
ETHICAL VEIWS TO THE USE OF WOOD- CONS
If the wood that you are using is not framed than it is likely that it has caused deforestation somewhere.
Deforestation causes animals to flee from their natural homes and is not ethically good
ENVIRONMENTAL VIEWS OF USING WOOD- PROS
When trees are growing they absorb greenhouse gases
Trees are natural so after they have been used they can be recycled of will decompose faster
ENVIRONMENTAL VIEWS OF USING WOOD-CONS
If deforestation was used in the obtaining of the wood then it has caused major problems to wildlife somewhere in the world
The burning of wood releases greenhouse gases
The processed used to cure timber may involve dangerous chemicals
SUSTAINABILITY OF TIMBER- PROS If timber is farmed
correctly and in the right environment then it is totally sustainable
Wood is the only totally sustainable building material in the world
SUSTAINABILITY OF WOOD- CONS If wood is not
farmed properly it causes many issues for the environment
This includes loss of habitat for animals and loss of natural forests.
INNOVATIONS IN TIMBER- GROWING New technologies in
the breeding growing and harvesting of wood.
These have resulted in massive increases in the amount of sustainable timber farms across the world
NEW INNOVATIONS IN TIMBER- CUREING Australian scientists
have discovered a new way to cure wood.
The use of microwaves to open up the fibres in the timber have resulted in less waste of chemical, using fewer chemicals to cure and a cheaper way to create cured timber.
NEW INNOVATIONS IN TIMBER-BENDING AND PROCESSING
Australian scientist are also trying out a new automated bending machine.
It uses microwaves as well to loosen the fibres in the wood making them easier to bend
This has resulted in faster making of timber products and also a cheaper alternative to make it
