Where did I leave off? Oh yes. In my last post, The Myth of the Biodegradable Poop Bag – Part 1, you just threw the poop bag in the trash.
Here is where I get all “science-y” on you.
In the old landfill days, people dumped stuff in a pit in the ground. Much of the stuff decayed, releasing methane and other gasses into the atmosphere. When rain passed through the decaying matter produced trash juice, called leachate, that soaked into the ground.
Methane is one of the greenhouse gasses and this leachate contained contaminants that made their way into groundwater and polluted our drinking water. As population and trash production grew, this posed a big problem for the environment and those in the waste industry.
One solution – the trash compacting.
So, your happy little bag of poop makes its way into a garbage truck and to a landfill. At the landfill, garbage is compacted very tightly by heavy equipment to make room for more trash. This serves another purpose too.
By tightly compacting the trash, all air is essentially squeezed out of the trash pile and it is covered with another layer of trash. This robs the trash of air and sunlight that is essential for biological and ecological functions……LIKE DECOMPOSITION.
So, I hate to tell you, but those little poop bags are going to sit there for basically eternity until some future archaeologist finds it.
So buy the biodegradable bags to help free us from our dependence on petroleum. Plastic is a by-product of oil refining and accounts for 4% of the world’s total oil production. Buy them because they use renewable resources – like corn. But – and I hate to crush your dream…really – don’t envision those little baggies turning to dirt in the landfill because they don’t.
Unfortunately, dog poop does not belong in your curbside yard waste either (except in maybe one or two locations around the country I hear) so don’t even think about it. Commercial composting facilities do not have the technology to raise the temperature of the compost enough to destroy the bacteria and pathogens in dog poop.
What do you think about all this?
