Plastic Neutrality in Green Dialysis: A Pilot Study Exploring Plastoconcrete for Circularity

Background: Dialysis treatment generates substantial plastic waste, with 41% constituting the total waste stream. Traditional disposal methods (incineration, pyrolysis) worsen carbon emissions. landfill or recycling are legally restricted. This study investigates plastic neutrality as a solution, focusing on the use of surrogate plastic pebbles in plastoconcrete (PC) for a circular economy. Methods: We converted 2,000 dialysis-equivalent plastic waste units into pebbles and distributed them to institutions for conversion into PC bricks, planters, and Ganesha idols. After six months, we compared PC products against traditional alternatives (kiln-baked bricks, plastic pots) in terms of strength, durability, and cost-effectiveness. Additionally, we assessed the effectiveness of Ganesha idols in raising awareness. Results: Our findings demonstrate successful conversion of 4 tonnes of plastic waste into 2.8 tonnes of pebbles. Six polytechnic colleges and four NGOs utilized the pebbles, each processing an average of 250 kg. PC bricks exhibited superior strength, reduced weight, and cost-competitiveness compared to kiln-baked bricks (cost: 50 cents/kg). PC planters offered enhanced durability and aesthetics, effectively replacing plastic pots in college gardens. The distribution of Ganesha idols to healthcare professionals served as impactful awareness tools. Conclusion: Plastoconcrete is a promising solution for achieving plastic neutrality and fostering a circular economy in green dialysis. Future research will focus on scalability, long-term impact, and the integration of a plastic credit model into green dialysis.Institution Students making plastoconcrete bricks, pots and finished items
