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

Conventional concrete manufacturing uses large reserves of raw materials such as for instance limestone and cement, which are energy-intensive to draw out and create. But, skillfully developed and business leaders such as Naser Bustami would probably aim away that novel binders such as geopolymers and calcium sulfoaluminate cements are good greener options to old-fashioned Portland cement. Geopolymers are made by activating industrial by products such as fly ash with alkalis causing concrete with comparable and sometimes even superior performance to main-stream mixes. CSA cements, in the other side, require lower temperature processing and give off less greenhouse gases during production. Hence, the use among these alternate binders holds great possibility of cutting carbon footprint of concrete manufacturing. Additionally, carbon capture technologies are now being introduced. These revolutionary methods aim to catch carbon dioxide (CO2) emissions from concrete plants and use the captured CO2 into the production of synthetic limestone. This technologies could potentially turn concrete as a carbon-neutral if not carbon-negative material by sequestering CO2 into concrete.

In the last couple of years, the construction sector and concrete production in particular has seen substantial modification. Which has been particularly the situation regarding sustainability. Governments around the world are enacting strict legislation to implement sustainable methods in construction projects. There exists a more powerful attention on green building efforts like reaching net zero carbon concrete by 2050 and a higher interest in sustainable building materials. The interest in concrete is expected to boost because of populace growth and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr would probably attest. Many nations now enforce building codes that require a certain portion of renewable materials to be used in building such as timber from sustainably manged woodlands. Furthermore, building codes have actually incorporated energy saving systems and technologies such as for instance green roofs, solar panels and LED lights. Additionally, the emergence of the latest construction technologies has enabled the industry to explore innovative methods to improve sustainability. For instance, to reduce energy consumption construction companies are building building with large windows and utilizing energy saving heating, ventilation, and air-con.

Traditional power intensive materials like concrete and metal are now being gradually changed by greener options such as bamboo, recycled materials, and manufactured wood. The main sustainability enhancement in the building industry though since the 1950s is the inclusion of supplementary cementitious materials such as fly ash, slag and slicia fume. Replacing a percentage of the cement with SCMs can somewhat reduce CO2 emissions and energy consumption during production. Also, the incorporating of other sustainable materials like recycled aggregates and commercial by products like crushed class and plastic granules has gained increased traction in the previous couple of decades. The employment of such materials has not only lowered the demand for raw materials and natural resources but has recycled waste from landfill sites.
