What really happens to the plastic you throw away - Emma Bryce

  • 0:07 - 0:10
    This is the story
    of three plastic bottles,
  • 0:10 - 0:12
    empty and discarded.
  • 0:12 - 0:14
    Their journeys are about to diverge
  • 0:14 - 0:19
    with outcomes that impact nothing less
    than the fate of the planet.
  • 0:19 - 0:21
    But they weren't always this way.
  • 0:21 - 0:26
    To understand where these bottles end up,
    we must first explore their origins.
  • 0:26 - 0:30
    The heroes of our story
    were conceived in this oil refinery.
  • 0:30 - 0:31
    The plastic in their bodies
  • 0:31 - 0:36
    was formed by chemically bonding
    oil and gas molecules together
  • 0:36 - 0:37
    to make monomers.
  • 0:37 - 0:43
    In turn, these monomers were bonded
    into long polymer chains to make plastic
  • 0:43 - 0:47
    in the form of millions of pellets.
  • 0:47 - 0:51
    Those were melted at manufacturing plants
    and reformed in molds
  • 0:51 - 0:55
    to create the resilient material
    that makes up the triplets' bodies.
  • 0:55 - 0:58
    Machines filled the bottles
    with sweet bubbily liquid
  • 0:58 - 1:02
    and they were then wrapped, shipped,
    bought, opened, consumed
  • 1:02 - 1:06
    and unceremoniously discarded.
  • 1:06 - 1:07
    And now here they lie,
  • 1:07 - 1:10
    poised at the edge of the unknown.
  • 1:10 - 1:15
    Bottle one, like hundreds of millions
    of tons of his plastic brethren,
  • 1:15 - 1:17
    ends up in a landfill.
  • 1:17 - 1:19
    This huge dump expands each day
  • 1:19 - 1:24
    as more trash comes in
    and continues to take up space.
  • 1:24 - 1:28
    As plastics sit there being compressed
    amongst layers of other junk,
  • 1:28 - 1:30
    rainwater flows through the waste
  • 1:30 - 1:34
    and absorbs the water-soluble
    compounds it contains,
  • 1:34 - 1:37
    and some of those are highly toxic.
  • 1:37 - 1:41
    Together, they create a harmful stew
    called leachate,
  • 1:41 - 1:44
    which can move into groundwater,
    soil and streams,
  • 1:44 - 1:48
    poisoning ecosystems and harming wildlife.
  • 1:48 - 1:54
    It can take bottle one an agonizing
    1,000 years to decompose.
  • 1:54 - 1:59
    Bottle two's journey is stranger
    but, unfortunately, no happier.
  • 1:59 - 2:02
    He floats on a trickle
    that reaches a stream,
  • 2:02 - 2:04
    a stream that flows into a river,
  • 2:04 - 2:07
    and a river that reaches the ocean.
  • 2:07 - 2:08
    After months lost at sea,
  • 2:08 - 2:13
    he's slowly drawn into a massive vortex,
    where trash accumulates,
  • 2:13 - 2:18
    a place known as
    the Great Pacific Garbage Patch.
  • 2:18 - 2:22
    Here the ocean's currents have trapped
    millions of pieces of plastic debris.
  • 2:22 - 2:27
    This is one of five plastic-filled
    gyres in the world's seas.
  • 2:27 - 2:32
    Places where the pollutants
    turn the water into a cloudy plastic soup.
  • 2:32 - 2:36
    Some animals, like seabirds,
    get entangled in the mess.
  • 2:36 - 2:41
    They, and others, mistake the brightly
    colored plastic bits for food.
  • 2:41 - 2:45
    Plastic makes them feel full
    when they're not,
  • 2:45 - 2:47
    so they starve to death
  • 2:47 - 2:50
    and pass the toxins from the plastic
    up the food chain.
  • 2:50 - 2:53
    For example, it's eaten by lanternfish,
  • 2:53 - 2:55
    the lanternfish are eaten by squid,
  • 2:55 - 2:57
    the squid are eaten by tuna,
  • 2:57 - 3:00
    and the tuna are eaten by us.
  • 3:00 - 3:03
    And most plastics don't biodegrade,
  • 3:03 - 3:07
    which means they're destined to break down
    into smaller and smaller pieces
  • 3:07 - 3:09
    called micro plastics,
  • 3:09 - 3:13
    which might rotate in the sea eternally.
  • 3:13 - 3:17
    But bottle three is spared the cruel
    purgatories of his brothers.
  • 3:17 - 3:19
    A truck brings him to a plant
  • 3:19 - 3:22
    where he and his companions
    are squeezed flat
  • 3:22 - 3:25
    and compressed into a block.
  • 3:25 - 3:28
    Okay, this sounds pretty bad, too,
    but hang in there.
  • 3:28 - 3:29
    It gets better.
  • 3:29 - 3:32
    The blocks are shredded
    into tiny pieces,
  • 3:32 - 3:34
    which are washed and melted,
  • 3:34 - 3:38
    so they become the raw materials
    that can be used again.
  • 3:38 - 3:42
    As if by magic, bottle three
    is now ready to be reborn
  • 3:42 - 3:44
    as something completely new.
  • 3:44 - 3:48
    For this bit of plastic
    with such humble origins,
  • 3:48 - 3:51
    suddenly the sky is the limit.

We’ve all been told that we should recycle plastic bottles and containers. But what actually happens to the plastic if we just throw it away? Emma Bryce traces the life cycles of three different plastic bottles, shedding light on the dangers these disposables present to our world.
