Software apps and online services
Hand tools and fabrication machines
One day, I walked to an overseas mall. There we don't need to do something to open it without touching it without stepping on it, just approaching it or bringing our hands closer, we are hygienic without touching the garbage can to dispose of the trash. From there I found inspiration to make it more sophisticated by adding feature features to notify when the trash can is full and connected online. So that later when a full garbage can can be handled by a cleaning service.
