Huge amount of wastes are being generated, and even though the incineration process reduce the mass of wastes to a large extent, large amount of residues are still remain. The sustainable development of the system should decrease the waste-to-energy ratio continuously through the planned reuse of materials. This paper reviews the existing studies on recycling municipal and construction solid waste for the manufacture of Geo polymer composites. The principal findings of this work reveal that municipal and construction solid waste could be successfully used into Geo polymer composites as an alternative in the forms of precursor, aggregate, additive, reinforcement fibres, or filling material. Additionally, the results indicate that although the inclusion of such waste might depress some attributes of Geo polymer composites, proper proportion design and suitable treatment technique could solve these detrimental effects. Finally, a brief discussion is provided to identify the important needs in the future research and development for promoting the utilization of solid waste materials in the forthcoming sustainable geo polymer industry. In summary, this work offers guidance for a greener approach to building – scoring favourably in environmental performance for being relevant to resource conservation, landfill diversion, and waste recycling.

Global warming and climatic changes due to pollution have triggered the global efforts to reduce the concentration of atmospheric carbon dioxide. The carbon dioxide capture and storage method is considered as a strategy or plan of action for meeting carbon dioxide emission reduction targets. This paper aims at providing an intensive review of various carbon capture and storage techniques, transportation of carbon dioxide & the utilization of this captured carbon dioxide in the construction industry. It also provides a huge perception of the manufacturing process of various construction materials using carbon dioxide. This review may present a clear understanding of the carbon upcycling technologies & everything we do is geared towards a goal of creating a circular economy & awaken new ideas to promote its practical application in construction materials.
Keywords-Carbon abatement technology, Carbon capture, Carbon storage, Carbon transportation, Safety and tracking.
Green buildings are constructed mainly using sustainable materials which create healthy environment inside the building by reduced product emissions. The introduction of the translucent concrete into green buildings created a new innovation in sustainable construction. The ability to introduce refined natural lighting whereas maintaining privacy provides large environmental benefits additionally to its aesthetic ones, as well as reducing the cost of heating and lighting. The aim of the paper is a detailed study on the current status and past studies in the area of translucent concrete. Anyway, this new building material is in its developing stage and it has a wide scope in the future.
Keywords: Energy savings, Green buildings, Light transmitting characteristics, Optical fibers, Sustainable construction, Translucent concrete.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
