„Golden Retriever“

Background

Technology advances have lead to miniaturization of technology, but still as small as these sensors and storage devices might all get, it is still material that is not bio resobable and thus will physically leave the body at some point in time.

Problem

Modern sewage systems are not constructed to handle an increasing number of disposable sensors. This poses a logistic but also an environmental problem if in the future the use of these types of sensors will increase.

Actual Challenge

How will the sensor or its non-dispersible parts be retrieved once excreted from the body? This might be at the rest-room or sewage works level. How could a recycling circle be set up?

Can you find a solution to this challenge?
