The
latest technologies
has allowed for the
easier segregation
of waste types on
site and the reuse
within the
construction of the
replacement
building. On site
crushers allow the
demolished concrete
to be reused as type
1 crushed aggregate
either as a piling
mat for ground
stabilization or as
aggregate in the
mixing of concrete.
Timber
waste can be
shredded using
special timber
shredders and
composted, or used
to form manufactured
timber boards, such
as MDF or Chipboard.
At
the end of a
building’s life,
demolition generates
large amounts of
materials that can
be reused or
recycled,
principally wood,
concrete and other
types of masonry,
and drywall. Rather
than demolish an
entire building,
consider
“deconstructing” all
or part of the
structure.
Deconstruction is
the orderly
dismantling building
components for reuse
or recycling. In
contrast to
demolition, where
buildings are
knocked down and
materials are either landfilled or
recycled,
deconstruction
involves carefully
taking apart
portions of
buildings or
removing their
contents carefully
with the primary
goal being reuse. It
can be as simple as
stripping out
cabinetry, fixtures,
and windows, or as
involved as manually
taking apart the
building frame.
