Cycle of wood

 
Wood goes through 2 constant cycles.
The CO ² cycle, in which CO ² is retained in the timber during growth of the trees. This CO ² is released again when the wood is broken down or incinerated. The same CO ² is then available again for young trees, so they can grow and form new wood.
 
In addition, the wood is also recycled. The CO ² stays in the timber and therefore does not return freely in the air.
After use in construction or furniture wood, the can, for example, still serve as raw material for the wood panel industry, and then as biomass for energy (which is returned in the cycle CO ²).

Wood as a building material has some unique ecological features. So it is the onlywidely available renewable resource. In addition, wood retains CO2 and thus reduces its concentration in the air. That slows global warming. Finally, timber gives oxygen. Yet, these natural processes that occur in a forest are only optimal, if there is an active forest management.

The social importance of wood is really clear, if you look at the whole life cycle of wood. And compare it with other materials.
This exposes tin ecological assets:

  1. Wood processing slows rural depopulation
    Small woodworking companies call the shots in the wood sector. They prefer to develop their activities close to the source: the forest. Thus the wood industry binds the population to its own region.
  2. Logging pollutes less
    Compared with mines or oil wells, logging pollutes much less than the extraction of other materials.
  3. Timber transport has a limited impact on the environment
    The distance between production and processing of wood is usually small. This reduces both energy consumption and traffic congestion.
  4. Wood processing consumes little energy
    Wood processing has low power consumption. Reason? Wood usually does not undergo drastic process. To produce one ton of wood takes one hundred times less energy than a ton of aluminum.
  5. Timber production emits less sulfur
    In comparison with wood, the production of a steel structure emits five times more sulfur dioxide (SO2) in the atmosphere.
  6. Timber construction requires less energy and water
    Timber construction is a 'dry' construction method not only with less water. Also the drying process requires less energy.
  7. Wood creates a healthy indoor environment
    Wonen in een houten huis is gezonder. Huizen met veel hout voelen ook warmer aan. Voor eenzelfde warmtegevoel ligt de temperatuur er gemiddeld twee graden lager dan in een traditioneel gebouwde woning.
  8. Wood has a higher insulation capacity
    Wood insulates better than concrete, aluminum or steel.
  9. Wood is biodegradable
    Of all building materials, wood is the best biodegradable material.
  10. Wood does not create waste problems
    Most wood can be recycled and the end of it's cycle. What remains can also be used as fuel.
