Does Senil generate much trash as a Synth? And if you have the time to explain, I'd love to hear how it's handled in your lore if any! Would be willing to read a ton.
Ooh, this is an interesting one! In terms of Senil specifically, he doesn't generate too much trash outside of the usual amount for "existing day-to-day" - small bits of plastic and paper waste due to packaging, cardboards, metal shavings, small faulty electronics components, things like that. Since he's battery-powered most of the time, he only needs the occasional metals to give his nanites material to repair and/or grow with (unless his battery tissue itself inflates...), so his overall trash output is pretty minimal. He does have a bio-burner to convert as much energy as possible from biomass into energy for whenever he's trekking somewhere far from power, especially if it's somewhere without consistent access to solar power, but it takes energy to produce energy from it. Even though he could eat spare bits of plastic, paper, cardboard, leaves, etc. to help keep him powered on, small amounts like that usually take more energy to convert than they actually produce, so he practices "leave no trace" whenever possible. He has tried to get more efficient bio-burners that use different processes to convert biomass into energy, but they end up getting rejected by his neurology often times since his power circuitry ended up integrating very poorly when he was young and developing; he just has to take whatever works with him and hope it integrates cleanly enough. If anything, "broken modules" ends up being his most consistent trash output, but usually they can be repaired or repurposed into something else that works just fine. If it can't be... well, he'll either eat it or sell it for scrap.
