1 Buying soda in 12 oz aluminum cans or 2 liter plastic bottles.2 Microwave popcorn or popping it on the stove in a pan.
1) aluminum canA greater portion of aluminum is recycled due to its greater value and ease of separation from the garbage waste stream (metal can being heavier than plastic bottle and conductive-assists in the separation technology) 2) if you add the cost (not $$ but the cost associated with environmental impact) and waste generated from the microwave popcorn package (including the metalized portion of the bag that adsorbs microwave heat-look at the side of the bag that is down when in the microwave), I would go for popcorn on the stoveIf you have a good cast iron pan with a lid, you can make some GREAT kettle corn on the stove top (gas or electric).
