Disposable paper cups are convenient for on-the-go beverages, but concerns have emerged about their safety. These cups are typically lined with a thin plastic film to prevent liquid from soaking through the paper. However, when exposed to hot liquids, this plastic layer can degrade, releasing microplastics (MPs) into the drink. Studies have shown that within just 15 minutes of contact with hot liquids, significant amounts of these microplastics can leach into the beverage. These microplastics, once ingested, can carry harmful contaminants like toxic heavy metals and other pollutants. Are Paper Cups Really Safe for Hot Beverages?A recent research from IIT Kharagpur revealed that paper cups release harmful chemicals into your drink. According to the study led by Dr Sudha Goel, Associate Professor at IIT Kharagpur, when a hot liquid (around 85-90°C) is poured into a paper cup, the microplastic layer begins to degrade within just 15 minutes. This process releases approximately 25,000 micron-sized microplastic particles into 100 ml of the beverage. Over time, these microplastics can accumulate in the body, leading to potential health risks. An individual drinking three cups of tea or coffee from paper cups daily could ingest around 75,000 microplastic particles, invisible to the naked eye.These microplastics don’t just pose a physical risk. They can also act as carriers for harmful substances like toxic heavy metals (Palladium, Chromium, Cadmium) and other organic pollutants. Once ingested, these contaminants could have serious health implications, including toxicity and disruptions in bodily functions.What Are The Alternatives To Paper Cups?The research also emphasizes that alternatives to single-use paper cups need to be carefully evaluated. While shifting away from plastic was necessary, paper cups are not necessarily the safest or most sustainable choice. Professor Virendra K Tewari, Director of IIT Kharagpur, suggests that traditional alternatives like earthenware or more eco-friendly products rooted in India’s sustainable practices could be a healthier and environmentally responsible solution.Health Impacts Of Consuming MicroplasticsThe health impacts of consuming microplastics are still under investigation, but initial findings suggest that prolonged exposure could lead to digestive issues, inflammation, and long-term effects due to the accumulation of these particles in the body. The plastic lining in disposable cups, meant to prevent leaks, ironically becomes a source of contamination, raising questions about whether this widely-used option is truly safe for regular consumption.
