The purpose of this study is to determine how people with diabetes are disposing of various products and devices and at what rates so that better devices with less waste can be designed in the future.

The study aims to compare the amount of environmental waste that is generated during the management of diabetes of participants who are using a CGM and on multiple daily injection (MDI) or using an AID (automated insulin delivery) system. This study is expected to demonstrate which devices create the most waste and where opportunities exist to decrease diabetes device waste. We will collect data to describe both quantitatively (via daily survey) and qualitatively (via photography) the types of waste that are generated during the management of diabetes.

Inclusion Criteria:

• Person with diabetes (self-identified), either type 1 or type 2, who has been diagnosed at least 6 months earlier
• Age 18 years and above
• Use of a CGM
• Use of an insulin pump or on MDI
• Access to the Internet and e-mail
• Access to a smartphone with photographic capability
• Able and willing to provide informed consent

Exclusion Criteria:

• Failure to meet any of the inclusion criteria
• Any condition which, in the opinion of an investigator, would make the subject not qualified to participate in the study.

Adults with diagnosed diabetes mellitus (either Type 1 or Type 2) at least 6 months earlier, and treated with insulin and a continuous glucose monitor (CGM).

No plan to make individual participant data (IPD) available to other researchers
