Additionally, it can even be hard focused on collection and recycling. But if there are products that couldn't be recycled further, the collector could sell trash to burn off in the city power plant. I think there is a lot of potential for trash in this game.
Garbage sorting would be also cool with items having the percentage of materials they are made from: metal, plastic, wood, other organic, mineral etc and players could sort them into different bins with various rates of sorting quality or not sort at all. Recycler profession could unlock various sorting devices like shredders, magnetic separators, air centrifuges, and floating pools to further separate materials for later uses.
Would be awesome to have a garbage truck, and people put a waste bin at the side of their property, which the garbage collector can come pick up and use recyclers to make materials. I would drop my wood axe in the bin when I buy an iron axe, ditch my tent when I built my house. The garbage collector would turn those into wood logs and cotton cloth. Wet tailing would be collected and be turned into whatever makes sense for tailings to turn into. And bonus, you'll be able to craft a garbage truck early in the game. Or start off with just a cart.
This will be implemented in upcoming Update 14.
