Construction Scrap Sorter

WorldObject

A bulk material sorting system designed for construction and demolition waste. Through a series of graded mesh screens, it separates mixed debris into glass fragments, ceramic waste, and stone rubble for specialized recycling.

Notes

The Construction Scrap Sorter is a late-game industrial object that processes mixed construction waste into separate glass, ceramic, and stone recyclate streams. It requires a high-tier (Tier 3) enclosed room with at least 500 m³ of free volume to function, placing it firmly in advanced industrial facilities. If your town has reached the point of producing significant demolition debris, building a dedicated sorting station can turn that waste into valuable secondary resources rather than simply dumping it.
