Abstract - As urban areas grow, they will increasingly rely on naturally sourced materials, leading to increased transportation emissions and environmental impacts associated with activities like quarrying. In some areas of India, sand is even imported from other countries. However, recycling of construction and demolition waste (C&DW) can potentially help address these challenges. Currently, a significant portion of C&DW is either improperly disposed of or sent to landfills, resulting in land use conflicts and a loss of valuable construction resources.
The objective of our project is to extract and reuse sand from construction and demolition waste. While there are several recycling technologies for construction waste available, they concentrate mainly on extracting and utilizing coarse recycled aggregates. Our approach is different, as we implement selective removal of the sand and determine the ideal rotor speed of the crusher to extract the highest amount possible. Our aim is to enhance the quality of the extracted recycled sand and ensure its suitability for construction purposes.
Key Words: construction and demolition waste, sand, recycled aggregates, recycling, extraction.
