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

Conventional power intensive materials like concrete and metal are increasingly being slowly changed by more environmentally friendly alternatives such as for instance bamboo, recycled materials, and engineered timber. The key sustainability improvement within the building industry though since the 1950s happens to be the inclusion of supplementary cementitious materials such as fly ash, slag and slicia fume. Replacing a percentage of the cement with SCMs can notably reduce CO2 emissions and energy consumption during manufacturing. Furthermore, the inclusion of other lasting materials like recycled aggregates and industrial by products like crushed class and rubber granules has gained increased traction within the previous couple of decades. The utilization of such materials have not only lowered the demand for raw materials and resources but has recycled waste from landfill sites.

Within the last couple of decades, the construction sector and concrete production in specific has seen important modification. That has been especially the case in terms of sustainability. Governments across the world are enacting strict legislations to implement sustainable methods in construction ventures. There exists a stronger focus 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 anticipated to boost as a result of population growth and urbanisation, as business leaders such as Amin Nasser anNadhim Al Nasrwould probably attest. Numerous countries now enforce building codes that require a certain percentage of renewable materials to be used in building such as for example timber from sustainably manged forests. Furthermore, building codes have included energy saving systems and technologies such as for example green roofs, solar power panels and LED lighting. Furthermore, the emergence of the latest construction technologies has enabled the industry to explore revolutionary solutions to improve sustainability. For example, to cut back energy consumption construction companies are constructing building with big windows and making use of energy conserving heating, air flow, and ac.

Traditional concrete manufacturing utilises large stocks of raw materials such as limestone and cement, that are energy-intensive to draw out and produce. However, industry experts and business leaders such as Naser Bustami would likely point out that novel binders such as geopolymers and calcium sulfoaluminate cements are excellent enviromentally friendly options to old-fashioned Portland cement. Geopolymers are made by triggering industrial by products such as fly ash with alkalis causing concrete with comparable and on occasion even superior performance to old-fashioned mixes. CSA cements, in the other hand, need reduced temperature processing and give off less greenhouse gases during production. Hence, the adoption among these alternate binders holds great possibility of cutting carbon footprint of concrete manufacturing. Additionally, carbon capture technologies are increasingly being improved. These innovative approaches try to catch carbon dioxide (CO2) emissions from concrete plants and use the captured CO2 into the production of synthetic limestone. These technology may potentially turn concrete as a carbon-neutral if not carbon-negative material by sequestering CO2 into concrete.
