The idea is so good that there’s even a step-by-step guide on how to build your own shampoo dispenser using a Raspberry Pi 3 and a handful of building materials. A user by the name of Log GC has made one available to the general public on his Instructables account.

Plastic use is being extremely stigmatized, but SOAP Refill Station reminds us that plastic itself is not inherently bad—people just have to remember that it is reusable: “We don’t inherently have a problem with plastic. In many applications, plastic is the best material for the job, e.g. glass bottles are nice and all, but maybe they aren’t the best choice for a shower with a tile floor. Our goal is to attempt to break, or at the least slow the pandemic of the throw-away culture, with plastic as the primary target. We want to be there for that person asking themselves “But what can I do?” Well, You can start by refilling your soap.”
