Plastic Bags Costs Less They are Free : Its a MYTH

To see the real costs of "free" plastic bags, we must look at the "cradle to grave" multiple impacts and the effects of each phase of a bag's life. Here are some facts to illustrate the actual costs paid by our environment and society for the fleeting convenience of unlimited, free, single-use plastic bags.

Phase 1: Production Costs

  • The production of plastic bags requires petroleum and often natural gas, both non-renewable resources that increase our dependency on foreign suppliers. Additionally, prospecting and drilling for these resources contributes to the destruction of fragile habitats and ecosystems around the world.
  • The toxic chemical ingredients needed to make plastic produces pollution during the manufacturing process.
  • The energy needed to manufacture and transport disposable bags eats up more resources and creates global warming emissions.

Phase 2: Consumption Costs

  • Annual cost to US retailers alone is estimated at $4 billion.
  • When retailers give away free bags, their costs are passed on to consumers in the form of higher prices.

Phase 3: Disposal and Litter Costs

  • In a landfill, plastic bags take up to 1,000 years to degrade. As litter, they breakdown into tiny bits, contaminating our soil and water.
  • Collection, hauling and disposal of plastic bag waste create an additional environmental impact. An estimated 8 billion pounds of plastic bags, wraps and sacks enter the waste stream every year in the US alone, putting an unnecessary burden on our diminishing landfill space and causing air pollution if incinerated.
  • When plastic bags break down, small plastic particles can pose threats to marine life and contaminate the food web. A 2001 paper by Japanese researchers reported that plastic debris acts like a sponge for toxic chemicals, soaking up a million fold greater concentration of such deadly compounds as PCBs and DDE (a breakdown product of the notorious insecticide DDT), than the surrounding seawater. These turn into toxic gut bombs for marine animals which frequently mistake these bits for food.
  • Hundreds of thousands of sea turtles, whales and other marine mammals die every year from eating discarded plastic bags mistaken for food. Turtles think the bags are jellyfish, their primary food source. Once swallowed, plastic bags choke animals or block their intestines, leading to an agonizing death.
  • On land, many cows, goats and other animals suffer a similar fate to marine life when they accidentally ingest plastic bags while foraging for food.
  • Recycling requires energy for the collection, processing, etc. and doesn't address the above issues.

  1. This must be one of the most poorly researched posts I have seen on the subject of plastic bags. Not only is it full of erroneous claims; it also fails to list a single citation. Furthermore the author didn't offer any alternatives to the plasic bag.

    Without plastic people would be more likely to use paper bags with much higher costs to the environment than plastic bags or cheap foreign made reusable bags.
