A Review on Utilizing the Marine Biorefinery Waste in Construction Raw Materials to Reduce Land Pollution and Enhance Green Environment

This research mainly concentrates on eco-friendly construction material. Production of cement and concrete industries release huge amount of carbon dioxide (CO₂) and greenhouse gases which affect the environment and also there is a demand in construction material by man-made or nature. The construction sector finds an economic and eco-friendly cement replacement material to achieve the demand for green concrete that improve the energy conservation and better energy saving material. In marine Bio-refinery waste produce huge quantity of calcium carbonate, whose disposal is cause of major concern. Pre-eminent solution for this problem is utilizing the marine shell waste in cement and concrete. It revises the manufacturing process to reduce the raw material usage in production and adoptable material for global warming. Therefore, the researchers focus on marine waste sea shells as the replacement material in construction industry to save the energy and also give sustainable green material. As per the previous studies by the researchers to determine the chemical composition, specific gravity, water absorption, particle size distribution of seashells and also compressive, flexural and tensile strength of concrete. It shows the seashell is filler material that slightly increases the strength when compared to the conventional materials and therefore the sea shells are suitable for the construction field to manufacture the cement and concrete with eco-friendly manner.
