Building Materials: Recycled Building Materials.
Recycled steel saves more than 70% of the energy used in manufacturing
new steel from primary ore.
Recycling conserves material resources reduces waste disposal, embodied
energy cost and pollution through production. Recycling saves large
amounts of energy that would have been required in the manufacturing
phase.
Consumers should be encouraged to set goals to utilise recycled
products instead of new wherever possible. Be open minded to opportunities
which will allow this to happen, and flexible enough to make design
and structural elements change where needed. With the initial goal to
recycle clearly stated at the start, the project will have more success
in achieving its goal.
Recycling is sometimes made difficult by high labour costs which makes
it uneconomical to recycle or reuse many construction materials. The
cost of labour to remove nails from timber may well exceed the cost
of buying new timber, and consequently used timber is usually designated
to land fill. As owner builders, the Newtons' opted to do this labour
themselves rather then paying for out-sourced labour. With a routine
established, the job was not as difficult as the thought of it.
The quality, strength and length of timber obtained from demolition
sites are superior to modern timbers. The disadvantages working with
old hardwoods include added weight, hardness and the need to use special
woodworking tools. Environmentally and financially, recycled timber
remains the best option.
Recyling and the Newton House
The Newton House is pole framed. Poles have been purchased second
hand from an auction at the Brisbane Port Authority, Hemmant in 1999.
These are previously used as wharf pylons, their history indicated
that they would have initially been logged on Fraser Island, and were
taken to Horn Island. When pulled down to make way for concrete pylons,
they were transported back to Brisbane. The pylons are turpentine and
iron bark timber.
Hardwood for the structure and framework of the house was purchased
from a Cupitt Demolition in Beenleigh, the timbers from local
properties. The timber is seasoned and came in long lengths that are
rarely available.
The Newton House will utilise a large amount of second hand products
such as timbers, doors, windows and vanity basins. These have been sourced
from auctions, demolition yards and friends. The key is to keep an open
mind and opportunities follow. The financial and environmental benefits
are substantial.
