In an urban context, sustainability intertwines with social and economic challenges alongside environmental degradation. Architects and project managers can mitigate resource wastage by making informed choices, using suitable materials, applying appropriate processes, and leveraging available technology effectively. Excavated materials from various urban infrastructure projects are often dumped on the outskirts of cities, leading to changes in landforms and other environmental harm. This material, primarily soil, holds significant potential for conversion into compressed stabilized earth (CSE) blocks, which have proven highly efficient. This study aims to develop strategies for utilizing CSE blocks specifically in Mumbai. It involves comparing different soil samples from Mumbai to assess their characteristics, determine the optimal design mix, and ascertain the percentage of soil suitable for construction purposes. The research states that more than 50% of the content of the CSE blocks can contain excavated soil, costing similar to conventional building materials. Recommendations from the study include strategies for integrating this technique in standalone projects and complex developments. Given the substantial volume of excavated soil available, the practical application of this research is primarily geared towards large-scale projects contingent upon the appropriate composition of excavated soil.
