Project Outcome: Biodegradable mulch sheet made from starch and glycerin
Project Description: As part of the IBDP Group 4 collaborative science project, Dhyana an Yashashvi tackled a real-world environmental issue they observed during their Rural Immersion trip. While visiting local chili farms, they noted the widespread use of plastic tarps with perforations to support plant growth. Over time, these tarps degraded and contributed to microplastic pollution, affecting soil health and posing significant disposal challenges. Motivated to find a sustainable solution, the students drew upon their interdisciplinary knowledge from Chemistry, Environmental Systems and Societies (ESS), and Design Technology. Through a month of dedicated research and experimentation, they developed a biodegradable mulch cover made from starch and glycerin. Unlike conventional plastic tarps, this bioplastic alternative naturally decomposes, enriching the soil instead of polluting it. Their innovation offers a locally adaptable, cost-effective solution that supports agricultural productivity while protecting the environment. By blending scientific understanding with practical application, this project showcases how interdisciplinary collaboration can drive meaningful environmental change.
