 This paper examines the environmental impact of using single-use plastics versus reusing glassware in laboratory settings. The authors found that reusing glassware can reduce the carbon footprint by up to 11 times compared to single-use plastics. Additionally, they calculated the cost savings associated with reusing glassware over time and found that it was often cheaper than using single-use plastics. This paper provides evidence that reusing glassware is more environmentally friendly and economical than using single-use plastics.
