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

Conventional concrete manufacturing uses huge stocks of raw materials such as for instance limestone and concrete, that are energy-intensive to draw out and produce. Nonetheless, skillfully developed and business leaders such as Naser Bustami may likely aim away that novel binders such as for instance geopolymers and calcium sulfoaluminate cements are effective greener alternatives to traditional Portland cement. Geopolymers are built by activating industrial by products such as fly ash with alkalis resulting in concrete with comparable as well as superior performance to mainstream mixes. CSA cements, in the other hand, require lower heat processing and give off less carbon dioxide during production. Therefore, the adoption of these alternative binders holds great possibility cutting carbon footprint of concrete manufacturing. Furthermore, carbon capture technologies are now being engineered. These revolutionary methods aim to capture co2 (CO2) emissions from concrete plants and make use of the captured CO2 in the production of artificial limestone. These technology could potentially turn cement in to a carbon-neutral if not carbon-negative material by sequestering CO2 into concrete.

Over the past couple of years, the construction industry and concrete production in particular has seen significant modification. That is especially the case in terms of sustainability. Governments around the globe are enacting stringent legislations to apply sustainable methods in construction projects. There exists a more powerful focus on green building attempts like reaching net zero carbon concrete by 2050 and a greater demand for sustainable building materials. The interest in concrete is anticipated to increase as a result of populace 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 utilized in building such as timber from sustainably manged woodlands. Moreover, building codes have included energy efficient systems and technologies such as for example green roofs, solar power panels and LED lighting. Also, the emergence of new construction technologies has enabled the industry to explore revolutionary solutions to enhance sustainability. For instance, to reduce energy consumption construction businesses are constructing building with big windows and using energy saving heating, ventilation, and air-con.

Conventional power intensive materials like concrete and metal are increasingly being slowly replaced by more environmentally friendly alternatives such as for instance bamboo, recycled materials, and engineered wood. The main sustainability enhancement in the building industry however since the 1950s has been the inclusion 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 manufacturing. Moreover, the incorporating of other sustainable materials like recycled aggregates and commercial by products like crushed class and rubber granules has gained increased traction within the previous few years. The usage of such materials have not only lowered the interest in raw materials and resources but has recycled waste from landfill sites.
