I like this plan!
Especially the no-more-than-two plastic formulations part.
Glass can do some things plastics cannot - it can be sterilised by autoclaving without being softened/melted, and for work purposes it can contain organic solvents and mineral acids that will eat any plastic except maybe PTFE. But I agree with you, I would prefer to minimise glass and focus on re-using rather than recycling it.
With your organic waste stream, especially the solids, you could also consider sterilising that and using it to grow a cellulose-eating fungi such as Pleurotus (Oyster mushroom).
