bag of trash more than 5 pounds
T took issue with my opposition to regulating plastic bags in Pasadena. In my reply I focused on a clearly factual error he made either deliberately, because he was misinformed or by deviously conflating “landfill” and “litter stream.” I assume it was said to heighten the sense of urgency since the rest of the reply is about the horror of a future with plastic.
Ralph’s Grocery bag 1/8 oz
There in no way that plastic bags are 25% of the waste stream
and it is a checkable fact.
Trash can liner bag 5/8 oz
Do the math:
- Plastic grocery bags weigh an 1/8 of an ounce. (bags in trash are mostly these or smaller)
- Plastic trash bags weigh just over a half of an ounce. (This hold the trash)
- Lets estimate that on the high end plastic bags average weight is 1/4 ounce.
- so there are 4 bags in an ounce
- 16 ounces in a pound=64 bags in a pound
- round down to 5o (margin for error)
- a five pound bag of trash x 25% = 1.25 pounds of bags
- 50bags/pound x 1.25 pounds=62 bags
- which means more than 60 plastic bags would have to be in a small bag of trash to meet “T’s” assertion.
- Conclusion “use common sense to test facts before passing them along”
BTW I read somewhere that the people who would benefit most from a plastic bag ban would be the pulp and paper industry. Makes sense to me. You are fighting a commercial battle with the passion of a true believer.
