Sustainable Building and Construction
3.2.1.11.1 Reuse of components
The reapplication of used components is quantitative realisable only in a small scale
but it represents the qualitative higher recycling method compared with the material
recycling. It is a major contribution for the realisation of intelligent material cycles.
Therefore first of all the possibilities of its application should be reviewed in every
construction project.

lot of reusable components.
The reapplication of components in the same project represents the optimal way of
recycling. In general this is only the case during the refurbishment and modification
of buildings. Used components from other civil works are applicable in refurbishment
as well as new construction projects. The components can be supplied directly from
the demounting site or through an intermediate store, a processing or recycling
company or so called component markets and stores.
Complete buildings offered under the term “recycling buildings” can be dismantled to
individual parts and reconstructed somewhere else. Bricks, roof tiles, components
from trusses, wood truss ceilings or columns and massive timber parquet can be
reused for the same function if the fastening allows a non-destructive dismantling.
