Wood and its
Recycling
What is
wood ?
Wood is the hard substrate that compromises most trees, bushes and shrubs.
It consists of : Cellulose Hemi-cellulose Lignin
Trees provide us with more than 5,000 products that people use every day
From photographic film to paints and from toothpaste to tires, tree-based chemicals and other wood by-products are all around us
They provide shade, oxygen, fruit, nuts and wood products such as paper, furniture and housing etc
USES Fuel
Construction
Furniture and utensils
Engineered wood
In the arts
Sports and recreational equipment
WOOD RECYCLING
The process by which clean waste wood, containing no contaminants or hazardous materials such as glue, lead paint, asbestos or creosote, are ground into chips and used to make new products
Tree branches, stumps, pallets and clean scrap wood from construction sites are all examples of clean waste wood
Wood crushing
Thermal treatment
Separation
WOOD CRUSHER
The crusher reduces the wood from its original size to two inch long splinters
THERMAL PROCESS Gets mixed with hot gases
and other molecules Once heated they are
condensed and it is repeated again and again till it becomes light
That way the wood generates enough hydrocarbon gases to maintain the system in auto-combustion
SEPERATION STEP
Here the carbon is separated from the other minerals
The clean carbon is packed into airtight big-bags of 800 kg, while the other minerals are put into metallic drums.
BENEFITS OF RECYCLING
Reduces cutting of new trees
Preserves the forest habitat of many birds and animals
Reduces the incidence of soil erosion
Reduces landfill space
Increases job in economy
What can we do
now???
Using less paper is a great way to help save our ancient forests. Here are some ways that you can use less paper:
Write on both sides of every piece of paper try to use scratch paper or half sheets whenever possible
Put a cloth napkin in your backpack, purse, or lunch pail and use it instead of paper napkins
Take a canvas bag to the grocery store instead of using paper bags
Use cloth towels at home to clean up spills instead of paper towels and use real cups and plates instead of paper ones
100% post-consumer recycled paper
A fourth way we can use less wood is to build our homes beautiful, inexpensive earth-friendly, homes
TOGETHER WE CAN…
