Concrete production is major contributor to CO2 emissions, but there was a desire for greener options.

Old-fashioned energy intensive materials like concrete and metal are increasingly being slowly changed by greener alternatives such as for instance bamboo, recycled materials, and engineered wood. The primary sustainability enhancement within the building industry however since the 1950s was the introduction of supplementary cementitious materials such as fly ash, slag and slicia fume. Replacing a portion of the concrete with SCMs can dramatically reduce CO2 emissions and energy consumption during production. Also, the incorporation of other lasting materials like recycled aggregates and industrial by products like crushed class and plastic granules has gained increased traction in the past couple of years. The use of such materials have not only lowered the interest in raw materials and resources but has recycled waste from landfill sites.

Conventional concrete manufacturing utilises huge reserves of raw materials such as for example limestone and cement, that are energy-intensive to draw out and produce. Nonetheless, skillfully developed and business leaders such as Naser Bustami would likely aim out that novel binders such as for example geopolymers and calcium sulfoaluminate cements are effective greener alternatives to old-fashioned Portland cement. Geopolymers are formulated by triggering industrial by products such as fly ash with alkalis causing concrete with comparable if not superior performance to mainstream mixes. CSA cements, regarding the other side, need lower heat processing and emit less carbon dioxide during production. Hence, the adoption of those alternative binders holds great potential for cutting carbon footprint of concrete manufacturing. Additionally, carbon capture technologies are now being developed. These innovative solutions aim to catch co2 (CO2) emissions from cement plants and use the captured CO2 within the manufacturing of synthetic limestone. These technology could possibly turn cement in to a carbon-neutral and even carbon-negative material by sequestering CO2 into concrete.

In the last handful of decades, the construction industry and concrete production in specific has seen substantial modification. That is especially the situation when it comes to sustainability. Governments around the globe are enacting strict legislation to implement sustainable practices in construction projects. There is a stronger attention on green building efforts like reaching net zero carbon concrete by 2050 and a greater interest in sustainable building materials. The interest in concrete is expected to increase because of population growth and urbanisation, as business leaders such as Amin Nasser anNadhim Al Nasrwould likely attest. Many nations now enforce building codes that need a certain percentage of renewable materials to be utilized in building such as timber from sustainably manged forests. Additionally, building codes have included energy saving systems and technologies such as for example green roofs, solar panels and LED lighting. Also, the emergence of the latest construction technologies has enabled the industry to explore revolutionary methods to enhance sustainability. For example, to reduce energy consumption construction companies are constructing building with large windows and utilizing energy saving heating, air flow, and air conditioning.
