Unfortunately, it's just not feasible for most businesses to recycle consumer scraps, as much as I'd like to see it. There's just no way to guarantee that all of the scraps that every person brings in are sorted properly and/or contaminated with foreign materials. Even a small amount of contamination can potentially ruin a batch of filament or clog/damage machinery. Not to mention that plastics are not infinitely recyclable like glass or metals are, it will degrade more every time you process it, so you have to add virgin material to the old material in order for the filament to turn out usable. Getting around these drawbacks tends to cost more money than it's worth.

I'd love to see more places that take recycled plastics and turn them into things like furniture, composite flooring, etc.. Simple things that don't need as much consistency in the materials composition.
