Construction technologies are among the most critical in terms of negative impact on the environment. Burnt binders, primarily cement and air-lime, emit significant volumes of carbon dioxide and man-made heat. At the same time, a large amount of hydrocarbon fuel is also consumed for their firing. Therefore, to achieve sustainable development goals, the development of alternative binder formulations or innovative ways to produce traditional binders with low carbon emissions is necessary. The synthesis of low-carbon...

India generates over 500 million tonnes of agricultural waste annually, much of which is lignocellulosic biomass rich in silica, calcium, potassium, and carbon elements, which are favourable for catalytic applications. This study highlights the valorisation of abundant agro-wastes such as rice husk (up to 20% silica), coconut shell (74%-78% fixed carbon), sugarcane bagasse (45%-55% cellulose), and tamarind seed (rich in polysaccharides and carbon), as cost-effective and sustainable catalysts. Various preparation t...
