This is a great idea, I really like having more control of the outputs and also not having to mess with a lot of unnecessary stuff like solid fuel, ice and holmium ore. These are some things I think could be improved:
- Make the outputs stack
- Find a better way to visualize the inputs and outputs before placing
- Make the inputs flipable with V and H, which would make some builds more easy
- Think about some way of balancing the water output, if you use productivity modules, you have to get rid of a lot of water that would otherwise block the system
- Make recycler productivity research apply for the reprocessor
- Add some in game descriptions for the reprocessor and the different recipes
- Add some animation to easily see if it is working
- Fix the slurry pipe connection sprite, if multiple reprocessors are built in a row
