Plastic Bags In Landfill – Not A Problem

You hear it over and over again, “plastic bags do not decompose and will last a thousand years in a landfill” and “they will be here long after I am gone!”  A Google web search will show hundreds of articles with the same theme and in all cases the writers attempt to convey how bad this is and why we should ban plastic carryout bags.  Look at what some say:

  • Plastic bags are not biodegradable … and end up in landfills where they may take 1,000 years or more to break down into ever smaller particles that continue to pollute the soil and water. (West)
  • A plastic carrier bag will take up to 1000 years to break down once it is in the landfill.  Compare that to its useful life which can be measured in minutes – the length of time it takes to get our shopping home from the store before being dumped in the dustbin. (Green)
  • Plastic bags also have a hard time decomposing; estimates range from ten to twenty years when exposed to air to 500–1,000 years in a landfill. (Cadman)

But what do these writers NOT tell you?  They don’t tell you that the raw materials, oil and natural gas, from whose byproducts plastic carryout bags are made, were in the ground for thousands if not millions of years.  So all that we are doing is putting back into the ground what we extracted from it in the first place, but we put it back in a different and more stable form.

Plastic Bag Recycling Rate – A Non-Issue

Bag Ban Proponents like to point out that the recycling rate for plastic carryout bags is 5% or less and that because of the low recycling rate, plastic carryout bags should be banned.

Bag Ban Proponents totally miss the point.  When plastic carryout bags are reused as trash bags, waste can liners, to pick up pet litter, dispose of kitchen grease, dispose of dirty diapers, or the myriad of other uses and end up in the landfill filled with trash, they cannot be recycled.  Bag Ban Proponents appear to have a particularly difficult time comprehending this simple fact.

Reusable Bag Recycling Rate Lower Than Plastic Bags

The majority of reusable bags currently in use in California are made from non-woven Polypropylene (PP) or fabrics such as cotton.  While PP is technically recyclable, currently there is no recycling infrastructure for PP bags in the state of California.  Furthermore, although cotton bags are technically compostable, there is no composting facility currently available.  Hence, both PP and cotton reusable bags must be disposed of in the trash or landfill.

A very small percentage (much less than 5%) of reusable bags are made from High Density Polyethylene (HDPE) or Low Density Polyethylene (LDPE).  These bags are recyclable via the In-Store Recycling Bin at your local retail store.

Environmentalists like to say that the recycling rate for plastic grocery bags is only 5% and therefore they should be banned.  But the recycling rate for reusable bags is closer to 0%.  Should they not be banned?
