Advancing towards greener healthcare : innovative solutions through single-use mask waste to refuse-derived fuel utilization

The healthcare sector faces increasing challenges in managing the environmental impact of single-use masks and medical waste, prompting the exploration of innovative solutions for greener healthcare. This study investigates converting single-use mask waste into Refuse Derived Fuel (RDF) as a sustainable waste management approach. A quantitative analysis assessed the average waste generation of single-use masks in a healthcare facility over three months. The potential RDF production was estimated by calculating single-use masks' weight and calorific value. Additionally, Thermogravimetric Analysis was employed to evaluate the thermal behavior of RDF and its suitability as an alternative fuel source. The findings indicate an average monthly waste generation of 41,555 masks weighing 111.2 kg. RDF production from single-use mask waste yields a daily output of 3.706 kg, providing a promising solution to reduce medical waste. TGA analysis reveals a multi-step degradation process for RDF, with a significant mass loss between 300 and 500 °C, rendering it a viable renewable energy source. Converting single-use mask waste into RDF presents an opportunity for healthcare institutions to contribute to net-zero emission goals, reducing reliance on fossil fuels and embracing sustainable waste management practices.
