Recycling & scrap value toolkit

Recycling isn't just civic virtue — a household can offset $50-200/year in scrap value on aluminum, glass, and cardboard, more with electronics. These calcs turn "bag of stuff in the garage" into a dollar figure so you know whether the trip to the scrap yard is worth it.

    Electronic Waste Recycling Calculator

    Precious-metal recovery from PCBs, phones, and hard drives. A pallet of old CRT monitors can be worth surprisingly little; a bin of old phones can be worth surprisingly a lot.
