WOOD AND ITS DERIVATIVES
Sustainability In The Extraction An Use Of Wood
Wood is a biodegradable material decomposed by microorganisms and recycled by the biosphere, this feature makes it an environmentally friendly material this isn't actually quite that simple since the cultivation of wood and its industrial transformation into finished products that have a significant environmental impact.
Machines that consume fossils fuels or polluting chemical products are used to obtain wood boards, the best way to reduce the environmental impact of using a material is to apply the rule of the 3Rs (reduce, recycle and reuse)
REUSE
A lot of wood furniture can be given a new life in the home of someone else rather than throwing it away.
RECYCLE
Used furniture or scraped wood from packages or construction are collected at municipal recycling centres. They are then sent to factories where wood is reused as a raw material to manufactured artificial boards, make sawdust or manufactured pellets to be used in wood burners as fuel.
REDUCE
Many of the wooden packages use could be reduced or eliminated.
This is the process of wood
Stripping the bark
Cutting
Transport
Drying
Logging and pruning
Planning
Wood it is raw material of plant origin and its composed of cellulose and lignin
Sustainability In The Extraction An Use Of Wood
When the people who cuts the trees and then they lived on the floor they are contaminated the earth because they didn't used that wood and the people who have forest protected they clean, they safe that place and they protect that place for the people who cut the trees.
Softwoods
Are usually from conifer trees, with needle-shaped leaves. They grow quicky, contain a lot of resin and are pale-coloured. They are light and easy to work with.
Hardwoods
Usually come from deciduous trees. They grow slowly and have thick, compact trunks. They contain little resin and can be many different colours.
PROPERTIES OF WOOD
Wood is a very varied material
Wood is a soft material and a different harder material may scratch or penetrate it. This features makes it possible to use metallic nails to join together pieces of wood or to work easily by using steel tools.
Dry wood is a good thermal insulator. For this reasons, wooden houses are energy-efficient: they maintain temperatures inside the house inside the house efficiently. Dry wood doesn't conduct electricity but wet wood does.
Wood is very resistant to being stretched, compressed or bent. For this reason, it's still widely used in the construction of houses and other buildings.
Wood is not very dense. Most types of wood are less dense than water and float in it.
It's a biodegradable material. Wood is decomposed by fungi and insects such as termites. To make it more resistant to the passage of time and more durable, it's necessary to protect it from plagues.
Hygroscopy is the ability to absorb moisture from the environment. Wood is very hygroscopy, meaning it absorbs water. It must be protected from moisture because damp woods is more vulnerable to fungi and insects and because it expands when damp reducing its asthetic value.
Wood contains chemical energy inside it. It can be used as a fuel either by burning it directly or turning it into pellets or charcoal.
