Abstract

Background: People with diabetes benefit from continuous glucose monitoring (CGM) systems. A downside of these valuable aids for diabetes management is the generation of a tremendous amount of waste. This study aimed to quantify this CGM-related waste.

Method: Twenty-four used CGM sensors from two different manufacturers (8× FreeStyle Libre 2, 11× FreeStyle Libre 3, and 5× Dexcom G7) were dismantled manually and separated in case, circuit board, and battery. Each component as well as included packaging, applicator, and leaflet were weighed separately.

Results: Packaging, applicators, and leaflets accounted for most of the waste (FL2: 93.4 g; FL3: 58 g; G7: 108.1 g). The plastic case contributed mainly to the total sensor weight (FL2: 1.9 g/63% of 3.3 g; FL3: 0.5 g/49% of 1.1 g; G7: 1.9 g/59% of 3.2 g), whereas the weight of the electronic circuit board and battery varied (FL2: 0.8 g/25%, 0.4 g/12%; FL3: 0.2 g/17%, 0.4 g/34%; G7: 0.7 g/22%, 0.6 g/19%). Extrapolating these data based on annual worldwide usage of around 230 million glucose sensors, approximately 20,000 tons of packaging, applicators, and leaflets and 580 tons of glucose sensors are disposed of, including about 340 tons of casings, 130 tons of circuit boards, and 110 tons of batteries.

Conclusions: Our data highlight the potential for optimized resource utilization by reduction of packaging, sensor size, longer application periods, implementation of multiuse applicators, and the need for recycling options.

期刊介绍: The Journal of Diabetes Science and Technology (JDST) is a bi-monthly, peer-reviewed scientific journal published by the Diabetes Technology Society. JDST covers scientific and clinical aspects of diabetes technology including glucose monitoring, insulin and metabolic peptide delivery, the artificial pancreas, digital health, precision medicine, social media, cybersecurity, software for modeling, physiologic monitoring, technology for managing obesity, and diagnostic tests of glycation. The journal also covers the development and use of mobile applications and wireless communication, as well as bioengineered tools such as MEMS, new biomaterials, and nanotechnology to develop new sensors. Articles in JDST cover both basic research and clinical applications of technologies being developed to help people with diabetes.
