Turning old plastic into new filament for 3D printers

I recently printed my first 3D component using the Maker Bot at my local (awesome) maker space in Troy NY (The Tech Valley Center of Gravity). After attending a handful of maker events over the past month, and being in the local maker space, I became aware of the massive amount of plastic waste that is being generated by Maker Bots all over the world. ABS plastic which is most often used in this type of 3D printing unfortunately falls into plastic recycling category #7, or “other”, and is very difficult to recycle at typical municipal recycling centers.

I had the idea that it would be amazing to try to turn the broken, wasted or generally discarded 3D printed parts back into plastic strands that could be re-used in a Maker Bot. Luckily, someone else did it already:
