The safety of our project was always in our mind while working on it since the primarily goal of the badge is to be used outside of the lab. We decided to design it in a way that prevent our modified bacteria from escaping into the environment. The badge includes a ring filled with bleach which is mixed with the bacteria contained into the capsule once it has been used. The bleach will rapidly kill the bacteria and ensure that no one of them can escape.

Although it ensures that no bacteria will leave the badge alive when discarding it, another biosafety mechanism could be used in case of a capsule leak or even a break upon a hit. One way to prevent this kind of escape road is the introduction of a kill switch inside our bacteria. Several kill switches have been designed and registered as biobricks by multiple iGEM team during the past years. The implementation of one of them would add another barrier and lower even more the risk of our bacteria escaping.

We decided to make our badge in a way that limit its impact on the environment. The badge is mostly made out of Polylactic Acid, which is a biodegradable polymer. The badge is also fully reusable. The support can be kept by the user and the two others parts can be easily cleaned and replenish. The badge is also fully manufacturable using only 3D printers and polymers that are easily accessible.
