Innovative Sustainable Materials
Construction
activities have experienced a boom due to a rapid improvement in procument of
building materials. However, the current scenario in the booming construction
industry has posed many challenges due to some un sustainable aspects of the
highly polluting and the exhaustive nature of building materials. At the same
it has also created opportunities for innovative and unconventional resource to
emerge.
Among
these building materials, stand out due to their durability, cost effectiveness
and local availability.

- · GrassCrete
- · HempCrete
- · Bamboo
- · Recycled Plastic
- · AshCrete
Rather
than relying on new research and technology, straw bale building hearkens back
to the days when homes were built from natural, locally-occurring materials.
Straw bales are used to create walls inside of a frame, replacing other
building materials such as concrete, wood, gypsum, plaster, fiberglass, or
stone. When properly sealed, straw bales naturally provide very high levels of
insulation for a hot a cold climate, and are not only affordable but
sustainable as straw is a rapidly renewable source.
GrassCrete
As
its name might indicate, garsscrete is a method of laying concrete flooring,
walkways, sidewalks and driveways in such a manner that there are open patterns
allowing grass or other flora to grow. While this provides the benefits of
reducing concrete usage overall, there is also another important perk; improved
stromwater absorption and drainage.
HepCrete
is a concrete like material created from the woody inner fibers of the hemp
plant. The hemp fibers are bound with lime to create concrete like shapes that
are strong and light. HempCrete blocks are super-lightweight, which can also
dramatically reduce the energy used to transport the blocks, and hemp itself is
a fast-growing, renewable resource.
Bamboo
Bamboo
might seem trendy, but it has actually been a locally-sourced building material
in some regions of the world for millennia. The combination of tensile
strength, light weight, and fast-growing renewable nature of bamboo makes such
a promising building material for modern buildings. Used for framing buildings
and shelters, bamboo can replace expensive and heavy imported materials and
provide an alternative to concrete and rebar construction, especially in
difficult to reach areas, post-disaster rebuilding, and low income areas with
access to natural locally-sourced bamboo.
Recycled Plastic
Instead
of mining, extracting, and milling new components, researchers are creating
concrete that includes ground up recycled plastic and trash, which not only
reduce greenhouse gas emissions, but also reduces weight and provides a new use
for landfill-clogging plastic waste.
AshCrete
AshCrete
is concrete alternative that uses fly ash instead of traditional cement. By
using fly ash, a by-product of burning coal, 97 percent of traditional
components in concrete can be replaced with recycled materials.
