Collecting fixer is easy since the machine is designed to do that. The other chemicals dump to the waste port, making it harder to do. It may be easier to process by hand than trying to manipulate a hose on the drain.
Dilution rather than recovery is the answer for making it easy. But I think that's probably unworkable.
The machine's design criteria were for small volume but pro lab quality results. One shot use ensures the chems are always fresh. But in this case it works against the hobbyists.
