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

In the last couple of years, the construction industry and concrete production in particular has seen significant change. That is especially the situation when it comes to sustainability. Governments around the world are enacting stringent rules to implement sustainable methods in construction ventures. There is a more powerful focus on green building efforts like reaching net zero carbon concrete by 2050 and an increased demand for sustainable building materials. The interest in concrete is anticipated to increase because of population growth and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr would probably attest. Many countries now enforce building codes that want a certain percentage of renewable materials to be used in building such as timber from sustainably manged forests. Furthermore, building codes have included energy efficient systems and technologies such as for instance green roofs, solar panel systems and LED lighting. Also, the emergence of the latest construction technologies has enabled the industry to explore innovative solutions to enhance sustainability. For example, to lessen energy consumption construction businesses are building building with big windows and using energy-efficient heating, ventilation, and air conditioning.

Conventional energy intensive materials like tangible and metal are increasingly being slowly changed by greener alternatives such as for instance bamboo, recycled materials, and manufactured wood. The primary sustainability improvement in the building industry though since the 1950s has been the inclusion of supplementary cementitious materials such as fly ash, slag and slicia fume. Replacing a percentage of the concrete with SCMs can significantly reduce CO2 emissions and energy consumption during production. Moreover, the inclusion of other lasting materials like recycled aggregates and commercial by products like crushed class and plastic granules has gained increased traction in the past few decades. The employment of such materials have not only lowered the interest in raw materials and resources but has recycled waste from landfills.

Traditional concrete manufacturing utilises large reserves of raw materials such as for instance limestone and concrete, that are energy-intensive to draw out and create. But, skillfully developed and business leaders such as Naser Bustami would likely point out that novel binders such as geopolymers and calcium sulfoaluminate cements are good greener alternatives to old-fashioned Portland cement. Geopolymers are made by activating industrial by products such as fly ash with alkalis causing concrete with comparable and even superior performance to mainstream mixes. CSA cements, in the other hand, require lower temperature processing and emit less carbon dioxide during manufacturing. Hence, the use among these alternate binders holds great prospect of cutting carbon footprint of concrete manufacturing. Also, carbon capture technologies are increasingly being built. These innovative methods try to capture co2 (CO2) emissions from concrete plants and make use of the captured CO2 into the manufacturing of artificial limestone. This technology could possibly turn cement in to a carbon-neutral and on occasion even carbon-negative product by sequestering CO2 into concrete.
