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

Traditional concrete manufacturing uses huge stocks of raw materials such as limestone and cement, that are energy-intensive to draw out and produce. Nonetheless, skillfully developed and business leaders such as Naser Bustami would likely point down that novel binders such as geopolymers and calcium sulfoaluminate cements are good enviromentally friendly options to traditional Portland cement. Geopolymers are formulated by triggering industrial by products such as fly ash with alkalis resulting in concrete with comparable if not superior performance to conventional mixes. CSA cements, on the other side, need lower temperature processing and give off less carbon dioxide during production. Thus, the adoption of those alternate binders holds great possibility cutting carbon footprint of concrete manufacturing. Additionally, carbon capture technologies are increasingly being designed. These innovative techniques try to catch carbon dioxide (CO2) emissions from concrete plants and use the captured CO2 in the production of synthetic limestone. This technology may possibly turn cement as a carbon-neutral or even carbon-negative material by sequestering CO2 into concrete.

Conventional power intensive materials like tangible and steel are increasingly being gradually replaced by more environmentally friendly options such as for instance bamboo, recycled materials, and engineered timber. The main sustainability improvement in the construction industry though since the 1950s has been the inclusion of supplementary cementitious materials such as fly ash, slag and slicia fume. Substituting a portion of the cement with SCMs can dramatically reduce CO2 emissions and energy consumption during production. Moreover, the incorporating of other lasting materials like recycled aggregates and industrial by products like crushed class and rubber granules has gained increased traction in the past few decades. The application of such materials has not only lowered the demand for raw materials and resources but has recycled waste from landfills.

Over the past number of years, the construction sector and concrete production in particular has seen considerable modification. That is especially the case regarding sustainability. Governments across the world are enacting stringent legislations to apply sustainable techniques in construction projects. There is a more powerful attention on green building attempts like reaching net zero carbon concrete by 2050 and a greater demand for sustainable building materials. The demand for concrete is anticipated to boost because of population growth and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr may likely attest. Many nations now enforce building codes that want a certain percentage of renewable materials to be used in building such as for example timber from sustainably manged woodlands. Moreover, building codes have included energy saving systems and technologies such as for instance green roofs, solar panels and LED lighting. Furthermore, the emergence of the latest construction technologies has enabled the industry to explore innovative methods to enhance sustainability. For instance, to reduce energy consumption construction companies are building building with large windows and making use of energy saving heating, ventilation, and air conditioning.
