#Loop 3D printer concept turns plastic cups to scrubbers

Even though a lot of coffee shops offer discounts if you bring your own mug or tumbler when you buy from them, there’s still a lot of disposable plastic cups that go to waste, staying in landfills for decades. Since people will still probably continue using them, we need to find a way to be able to properly recycle of this particular kind of waste.

Loop is a concept for a 3D printer that will be able to do just that. It actually looks like a coffee maker or a water storage device but its function is to actually turn those plastic cups to create scrubbers that can also be used at the cafes. Therefore it really lives up to its name as it creates a sustainable circulation structure.

The 3D printer melts the plastic cups that you put in it by grinding them into small particles. They are heated to turn them into a “soft and malleable state” then cooled to solidify. They are then extruded into the desired filament shapes for printing. The scrubbers can then be used in washing dishes at the cafe.

The suggestion of the product designers is for cafes to use this to incentivize their customers into returning the plastic cups instead of just throwing it. It would be interesting to see if something like this can actually change consumer behavior.
