Big batches need you to be time efficient - or use a method that uses little work. So my suggestions are mainly needing oversight. Keep a fire extinguisher and safety gear handy though! Melting together Most filaments are melting at or around 200 °C. I recently got rid of my box of (PLA) waste material by putting them on a tray and melting them together in a ...

Resin is notoriously hard to handle, especially as exposure to air and light can and will cure it over time. The uncured resin is a hazardous material. Handling hazardous waste The rules for safe disposal can - generally speaking - be broken down to this: make sure the hazardous material can't contaminate water or food sources make sure the hazardous ...

A plastic shredder machine it's better then a melting/burning solution. It is faster and it doesn't produce fumes. Imagine burning PET bottles. For the shredder you need nothing but electricity for the motor. For plastic melting it would be much higher consumption. Additionally you could reuse shredded plastic for filament machine like Filastruder or ...

There are industrial shredders that will destroy just about anything. They are not cheap, at least from a hobbyist point of view. You might look into them because they might be right for the size of your company. Otherwise, you can simply melt them in a hot oven or with a heat gun. I would be careful about getting them too hot because some filaments release ...

If your company has a shredder which would handle large amounts of paper at one time, it should be able to handle the plastics from 3D printing. Most larger shredders can handle paper clips and staples. 3D plastics would be even less of a burden than them. You may need to break the pieces down into smaller chunks, but I doubt it would be an issue. Even ...

My 2 cents. If you have a CNC machine, you could "mill" them down. other than that, garden shredder/mulcher might suffice.

The IPA with the resin in it is a chemical waste and toxic to nature. As such, it needs to be given to a chemical waste handler. But those handlers do charge by volume, so you need to find a way to handle volumes reasonably. On the one hand, this means to not use huge volumes for washing the prints but reasonably small batches, and on the other hand to try ...
