Annual generation of C&D waste and industrial inorganic wastes in India is estimated to be 170 million tonnes and >300 million tonnes, respectively, which is projected to increase with the growing urbanization and economic development. Considering the constant expansion of the cement industry and its need to sustain, waste valourization has emerged...

Circular economy is a principle of economic activity that aims to ensure that resources remain in the economy for as long as possible. This may be achieved by reducing raw material consumption, waste generation, emissions and energy consumption. The waste and recycling industry represent the largest part of the circular economy today, and it is est...

... For instance, more than 60% of the total spending in the United States' civil infrastructure is for operation and maintenance expenses [1]. Among various environments impinging upon the behavior of construction materials (e.g., freeze-thaw, wet-dry, temperature, ultraviolet rays, carbonation, and deleterious chemicals), sulfuric acid is a representative source degrading the performance of structural materials in industrial and agricultural regions [2,3]. When concrete is exposed to sulfuric acid, substantial changes take place in mechanical and physical properties, thereby decreasing compressive strength by more than 20% [4,5]. ...
... Similarly, in Norway, national projects such as Kortreist stein (shorttravelled aggregates) and RESGRAM (recycled aggregates from excavation masses) are designed to develop technological processing solutions for sustainable use of high-quality excavation materials. Norway has a long tradition of adopting national policies and regulations, economic incentives, and extended producer responsibility to promote recycle operations and to create a market for high-quality waste materials (Karstensen et al. 2020). ...
... Moreover, process investigation is essential to find the most suitable RDF for a specific plant, according to the cost, availability of the fuel, continuity, heat content, physical and chemical properties, and finally, the impact on the quality of the clinker and cement. It is estimated that co-processing of 25,000 tons of AF instead of 7000 tons will increase the =TSR from 5% in 2020 to 20% in 2030 to produce one million tonnes of cement (Saha and Karstensen, 2019). Fig. 1 shows the TSR % of utilization of alternative fuels in various countries worldwide where the highest contributor is Austria followed by Norway. ...
