Paving the path to sustainability: Laterite quarry rejuvenation

Laterite, a characteristic rock found in tropical monsoon regions, prominently caps the hillocks in the midland areas of north Malabar, particularly in the Kannur and Kasaragod Districts of Kerala. Laterite quarrying stands as a major economic activity in certain parts of Kannur, driven by the high yields it produces. However, this practice has led to the formation of abandoned quarry pits, which pose significant environmental concerns and safety hazards.

This research proposes a holistic approach to repurpose these abandoned quarries into sustainable areas, employing simulations to determine the optimal design for these sites. The objectives include rejuvenating the landscape, designing spaces that meet community needs, addressing local climate challenges, serving as a model for similar sites in neighboring areas, studying local materials for sustainable applications, and reducing the environmental impact of quarrying.

The methodology involves identifying the environmental concern and conducting a comprehensive literature review to examine existing solutions. This is followed by performing site studies and live case studies to gather relevant data and information about the project location and current solutions. The project requirements are determined by addressing existing problems and community needs. Based on the findings, existing solutions and project formations are outlined.

In the initial stage, several iterations through simulations are conducted to ensure the effectiveness of the design, ultimately leading to the final design. Abandoned quarry pits, which are typically lower than ground level, present design challenges due to high humidity, low wind flow. However, these conditions also offer advantages such as passive shading and low temperature. To find the optimum design, software tools like Autodesk CFD and Design Builder are employed.

The expected result is an optimal design that effectively incorporates wind, light, and temperature considerations, serving as a model for the rejuvenation of more such abandoned quarries.
