We prepared Eco-bricks using discarded plastic bottles by filling them with clean, dry, and non-recyclable plastic waste. This activity helps reduce plastic waste and prevents it from reaching landfills, water bodies, and the natural environment. Eco-bricks can be reused as low-cost building materials for making garden borders, seating arrangements, small structures, and educational models. This initiative promotes waste segregation, recycling awareness, resource conservation, and sustainable living among students and the community. It also encourages the idea of “Waste to Useful” and shows how responsible waste management can contribute to a cleaner and greener environment.
