When I looked into this a couple of years back, the prices for ready-made filament extrusion setups looked like the target market was small business rather than individuals. And the recommended DIY method for breaking down plastic if you didn't have a machine shop was to get a paper shredder with metal blades (one of the models capable of shredding optical disks).
Much simpler to recycle printer waste into slab material. Or send it to a manufacturer that does recycling. Unless you're generating at least tens of kilos of waste a year, you're unlikely to break even any time soon by re-extruding, assuming the resulting filament is usable at all (ensuring consistent diameter and near-perfectly round cross-section is probably a PITA).
I would love for a small business to have one near me. I would literally give them the scraps for free. I've just been saving the chunks in a bin
I think in most cases you have to pay the price of postage. Some of the companies will offer you an incentive like free or discounted spools of recycled filament to offset this, but the only one I've found that's in Canada with me ( filaments.ca ) does not. Printerior Designs in the US apparently does (never dealt with them myself), and there are a couple in the EU.
Yeah Id give away all my filament do whatever with it in the name of environmentalism but I'm not paying for a company to sell my off cuts
