When Environmental
Impact is Considered
Jim Olsen
Today's business and cultural climate, protecting our natural resources and
the planet is not only necessary, but also good practice. The precast
concrete industry is also responsible for protecting our children's future
way of life. This industry ~ unique in that in many ways it has virtually no
impact on the environment, while in other it can have a major impact.
No
impact
Major concrete ingredients ‑ sand, stone and cement ‑are mined. No trees or
plants are destroyed. Most precast forms are made from steel, not wood. And
unlike other primary construction materials, precast concrete is produced
with a minimum of chemicals.
Due
to strict quality control, there is very little waste in precast concrete.
In most plants, even the concrete mixer was water is recycled for use the
following business day. Solid concrete from plant clean up is hauled to
landfills or used as clean fill at the plant.
Big
impact
Concrete products have a long service life, which eliminates the need for
replacement. Precast concrete products require less construction time in the
field, which means projects can be completed faster. Precast products allow
for less disruption of the construction site, less waste and less erosion
due to storm runoff.
Precast products include structures for storm water management ponds, box
culverts, precast inlets, reinforced concrete pipe for storm water control
manholes, pump stations aid utility vaults for sanitary sewers and force
mains.
Most
underground precast products assist in meeting EPA requirement for storm and
sanitary sewer control. At the same time precast products have a positive
impact on clean water.
Transportation products such as median barriers, bridges and highway
drainage structures contribute to more efficient road and rail routes. These
efficiencies cut travel time and therefore eliminate air pollution from
combustion engines.
The
obvious choice
Given a variety of considerations, especially those related to environmental
impact, it is clear that precast concrete products are the way to go.
Precast concrete is a green product and contributes much to maintaining a
clean environment for us, our children and future generations. In short,
life without precast is less healthy, less prosperous, less enjoyable and
certainly less green. Think "green," think precast concrete in the New
Millennium. |
