In Her Own Words
"I recently conducted my own research to study the correlation between single-use plastic, ocean waste plastic, tap water plastics, and income. At the YRI Fellowship, I want to continue my research on diverse topics, be able to present these at conferences, and be able to publish a paper."

The Research
Working with YRI mentors, Trisha tackled a critical environmental challenge: urban organic waste ending up in landfills. She designed simulation models comparing composting and biogas pathways, proving that circular economy strategies can dramatically reduce emissions and recover valuable resources at the household level.
Waste Loop: Simulating Circular Economy Models for Urban Organic Waste Management
Urban organic waste sent to landfills causes methane emissions and wastes recoverable resources
System dynamics and agent-based models simulating composting vs. biogas pathways
Compost potential, recycling potential, biogas generated, CO₂ avoided
Both circular pathways outperformed landfill disposal in emissions and resource recovery
Composting vs. Biogas: A Data-Driven Comparison
Trisha's research filled a gap in the literature by comparing composting and biogas pathways at the household scale. Her simulations showed that composting excels at nutrient recovery, while biogas provides renewable energy and fossil fuel substitution. High-participation households achieved near-complete landfill avoidance, demonstrating that individual action can drive systemic change.
"The results confirm that circular waste pathways outperform linear landfill disposal. Composting excels in nutrient recovery, while biogas provides renewable energy and emission reduction."
