Biodegradable products may not be so green

Once thrown out, biodegradable products — everything from trash bags and diaper liners to pens — are designed to break down relatively quickly and disappear into the natural environment. But these products may not live up to their green image, new research indicates.

“The implication is, it’s biodegradable, therefore, it’s better for the environment — and our point is: Well, not necessarily and not so fast,” said study researcher Morton Barlaz, who heads North Carolina State University’s Department of Civil, Construction, and Environmental Engineering.

These biodegradable products release a potent greenhouse gas, methane, as they break down in landfills, a problem aggravated by the relatively rapid rate at which they decompose.

Barlaz and colleagues looked at what happened when food waste, office paper, newsprint, municipal solid waste overall, and a biodegradable polymer called PHBO were buried in the average American landfill. Their modeling experiment showed that materials with higher rates of decomposition, like food waste and PHBO, ultimately emitted more methane into the atmosphere.

    A Lot that Green stuff nothing but a hoax of marketing and people eating it up.

    Hahahahahahahahaha!
    I guess the only way to save the earth is for us all to just kill ourselves, huh? Whatever we do we will be hurting the mother earth. You go first, I’ll be right behind you!

    I am sure you have compared the life cycle analysis of the type options of products to see what the reality is. Because you would know that most biodegradable utensils, etc, need to be properly treated and actually composted in order to really break down.

    When the environmentalists stop having children (massive carbon footprint) then I’ll start taking them seriously. How many kids does Gore have?

    I can certainly counter that with an equally moronic statement that is completely irrelevant.
    When Christians start believing that the earth is very very old I will take them seriously. How old do you think the earth is?
    Here is why what you said is ridiculous. Environmentalists want the leave the earth in better condition for the future generations. Also you used one person to judge an entire group of millions.
    Think, type, think. Or type, think, delete, think, type. Try it.
