Cell phones, like many consumer electronics, create a lot of waste... some in manufacturing, some in plastic in the landfills, plus some toxic waste in the batteries which usually get tossed in our landfills, too. Samsung may be on the right track with their new "Reclaim" cell phone that is solar-charged, and 40% of the plastic case is corn-based, biodegradable plastic.
That doesn't mean you can toss it in the compost pile, though. The other 60% of the plastic housing is still conventional, and won't break down any better than all those zillions of plastic bags in the landfills. BUT, it's a start.
Please do your part and recycle your old cell phone: here.
