Do your cookie sheets rust?
YesI use the professional aluminum onesThey don't warp or rustThey last for years and are fairly cheap at around $15 for 2 of them.
Doing both is a good ideaI prefer carrying a reusable container because the next person to use the plastic bottle might not recycle itAnd a reusable container lasts longer.
Carry a reusable container cuz it takes energy and fossil fuels to produce plastic bottles and to recycle themPlus reusable containers can come in different colors!! :-)
Carry a reusable containerNot all plastics that you send in for recycling actually get recycledMany end up in landfills anyway because there is a very limited market for recycled plastic.
Carry a reusable containerIt saves the pollution created when that new bottle is made (even if it is made from recycled materials)Also, there are no plastic bottles made from 100% recycled plastic (I don't think).
