Abstract:
Nowadays climate change is one of the major concerning factors due to increasing temperature
throughout the world. Carbon dioxide is a significant gas in the greenhouse effect which leads to global
warming. The construction industries released 40% carbon emissions from thermal calcium carbonate
decomposition especially in cement production and combustion of fossil fuels of non-renewable energy.
Renewable energy acts a vital part in the evolution of sustainability. Bioenergy has been deliberated
carbon neutral as the released carbon is absorbed by flora. This paper presents a comprehensive
review of the pozzolanic properties of waste ash and the performance of concrete. Ash is a by-product
produced from various resources such as rice husk, wood, coal, sawdust combustion, etc. Waste ash is
reused as supplementary material in eco-friendly concrete production. This helps for the disposal of
waste as well as contributes the sustainability by reducing carbon emission into the environment
