add more resonable recipes to the shredder

i.e. glass->broken glass, solar cell mono ->recycable, gold->gold scrap, paper->biomass
Something feasible in real life but not in the game.

Glass -> broken glass can be good for nuclear plants, but you can just stockpile broken glassor use molten glass wagon (with DLC) for that. Solar cells mono usually has uses (in space), but can make sense to have. But i see no reason for gold->gold scrap or paper->biomass.

If you have extra resources, dismantling them could be useful.
Gold doesn’t make much sense, and paper converted into biomass probably doesn’t either, but creating paper or plastic through the recycling of waste materials could be interesting.
Maybe you could add a waste sorter that divides trash to obtain recycled paper, plastic, glass, biomass (already present), and other materials.
This way, waste is reduced and new workable resources can be produced.
Essentially, you convert generic garbage into differentiated waste, making each material workable — just like industrial recyclable materials are already handled.
