Plastic Trash Forming Into "Plastiglomerate" Rocks

Posted by samzenpus on from the earth-plus-plastic dept.

sciencehabit (1205606) writes 'Plastic may be with us a lot longer than we thought. In addition to clogging up landfills and becoming trapped in Arctic ice, some of it is turning into stone. Scientists say a new type of rock cobbled together from plastic, volcanic rock, beach sand, seashells, and corals has begun forming on the shores of Hawaii. The new material--which the researchers are calling a "plastiglomerate"--may be becoming so pervasive that it actually becomes part of the geologic record.'

      Most of the plastic IS the dust - the big plastic garbage patch is made up of really tiny pellets after the big chunks have broken down.

      And what's happening looks like the plastic is breaking down and the pieces are starting to glob together forming some strange multi-material piece of plastic.

      Of course, once the dust gets small enough, the breakdown has to happen by UV only. In a big chunk, the plastic becomes brittle and the wave action helps break it down further, but once it's dust, it's too small for mechanical breakdown.

      The degradation of plastic material is a slow process that can occur mechanically, chemically (thermo- or photo-oxidative), and to a lesser degree, biologically (Kulshreshtha, 1992; Shah et al., 2008; Cooper and Corcoran, 2010). The persistence of plastic in the environment has been estimated to be in the range of hundreds to thousands of years, although longevity can increase in cool climates and where material is buried on the ocean bottom or under sediment (Gregory and Andrady, 2003). A recent study examining the accumulation of marine ocean debris at depths of 25–3971 m over a 22-year period shows that 33% of all debris in Monterey Bay, California, USA, is composed of plastic litter (Schlining et al., 2013). Similar results from other localities reveal that much of plastic debris is below

      the water surface (Goldberg, 1997; Galgani et al., 2000; Keller et al., 2010). This debris may be composed of high-density plastics or low-density plastics with fouled surfaces (Ye and Andrady, 1991; Goldberg, 1997; Gregory, 2009; Lobelle and Cunliffe, 2011). Given the low water temperatures and decreased exposure to UV light at greater depths within and below the photic zone, sunken plastic debris has good potential to persist and eventually form part of the rock record. On beaches, plastic debris, such as resin pellets, fragments, and expanded polystyrene up to 11 mm in size, may be preserved within the upper 5 cm of beach sediment (Kusui and Noda, 2003). Claessens et al. (2011) identified microplastics in beach sediment cores at depths down to 32 cm. In addition, Fisner et al. (2013), in their study of polycyclic aromatic hydrocarbons in pellets, were able to locate plastic debris at sediment depths as great as 1 m. However, we found no visible loose plastic fragments at depths >10 cm in sand on Kamilo Beach, Hawaii.

Reporting on environmental problems needs to better distinguish between serious harms like habitat loss and species extinction, resource conservation issues (one generation using everything up - like fresh water - disadvantaging later human generations), and what researchers call "fetishizing". The "fetish" is used when people are made to feel guilty about something (e.g. "waste") and continue to attach guilt and responsibility to the item based not on risk but on past human ownership. This can lead to regulations which disadvantage recycling (secondary copper smelters), secondary markets (e.g. used display devices and cell phones) disproportionately to the risk.

      There are some interesting academic papers on environmental fetishes and untended consequences of fixations based on previous human 'ownership' and 'guilt association'. Many environmentalists are scientists and are aware of the 'quasi-religion' of moral risk association, but are afraid to speak openly about it the same as the Renaissance's great thinkers were afraid to publicly pose their doubts about Christianity. The philosophers doubted much about sources of Christian ethics but were concerned about replacing it with anarchy. Scientific environmentalists have similar concerns about exposing "fetish" environmentalism without discrediting actual moral progress on stewardship.

  17. Typical AAAS tripe by bradley13 · · Score: 2, Insightful

    Here's the key phrase out of the abstract: "...melted plastic during campfire burning... [increases] the potential for burial and subsequent preservation". Why? Because lumps of melted plastic stick to sand or rocks, and hence are more likely to not blow away, be degraded by UV or whatever.

    This is a topic for a scientific paper, and deem headline-worthy by the AAAS? I knew there was a reason I cancelled my membership a couple of decades ago...

    So instead of releasing the carbon into the atmosphere we're pissed off because now we have ugly rocks that are made of trapped carbon?

    If this plastiglomerate can remain in the environment for eons, then I'm thinking we should make more of it, a lot more of it.

      it uses it therefor it traps. but I assume you meant the word "use" in some other way...

      we are pulling hydrocarbons from deep underground and if we continue to either burn it or allow it to decompose, it will become CO2 and contribute to the greenhouse effect. Anything that could sequester carbon long term is better than the nothing we are doing today.

      the eventual goal would be to stop pulling material out of the ground, and reverse the trend and put carbon back faster than we take it out. We're so far away from doing that that I don't believe there are any viable plans written up to accomplish it.

    For years we've been hearing from environmentalists how our use of nondegradable plastics is cluttering up the environment, but here we see the truth; the earth is using these plastics to produce new fossil carbon, for future generations to use for fuel! And as a bonus this is a carbon sink to limit global warming! I look forward to the day when I can build a deck out of petrified engineered lumber.
