    Waste: Withgott text v.6, chapter 22

    Waste: Defined as anything from human activity that is not saved or re-used
    MSW (municipal solid waste) vs. ISW (industrial solid waste)
    Typical waste stream:


    Consumption is proportional to waste in our society
    Affluence leads to waste (plenty of trees, so let's waste firewood!)
    Interesting map, note geographical and social patterns:

    You may have noticed these states on the sides of some of the bottles you drink from...

    Check this out:

    Orcas Island WA, costs $6 per BAG of trash. Lots of recycling there (also locked dumpsters).
    Recycling is complex, especially here on Hawaii island: where does your recycling go? Where did it go 5 years ago? What changed?
    HPA has two dumpsters behind maintenance: a recycling one and a trash one. Only one is weighed. Which one do you think? Why?




    Greenhouse gas emissions that are reduced by recycling:
    Closed and open loop recycling:



    RCRA and sanitary landfills: Make sure you understand both of these, as they are always on the AP exam...
    RCRA is the Resource Conservation and Recovery Act, part of the EPA regulating landfills:
    Resources=stuff
    Conservation=stuff we use or don't use (conservation)
    Recovery=recycling or safe disposal
    Act=something Congress decided

    Sanitary landfills: isolated from the groundwater, far from rivers, wetlands or earthquakes
    Make certain you understand "leachate" and why these produce methane...

    Incineration is another option, but produces extremely toxic ash that must be treated carefully:

    This is also where the nasty stuff from power plant scrubbers goes (recall last chapter on pollution)

    Look here: https://www.covanta.com/Our-Facilities/Covanta-Honolulu
    H-Power is trash to power, where the landfills on Oahu were full in the 1980's. One in Laie actually was created inside a volcanic crater that barfed up all the waste one year during a flood.

    Life cycle analysis (see also William McDonough in 'cradle to cradle'):
    His idea is "up-cycling" instead of re-cycling, essentially designing things so they could be used for other purposes.

    You might look for the red label ("1993") on trucks. Here are some common numbers:
    1075: Propane
    1203: Gasoline
    1202: Diesel fuel
    3334: Aviation fuel

    Look up BLEVE on youtube (Boiling liquid expanding vapor explosions)

    E-waste is a growing issue, but there are solutions:
    https://www.theverge.com/2018/4/19/17258180/apple-daisy-iphone-recycling-robot
    Daisy, the Apple robot that recycles iPhones.
    Question: why would the white mac laptops in our classroom cost more to recycle than the aluminum ones? Which is cheaper? Which is cheaper after counting the value of the parts inside each?

    Lead from e-waste:
    Liquid waste disposal:

    This is often done off-shore or into remote rivers away from prying eyes.
    Deep well injection is a temporary solution, this toxic material is not going away.
    Radioactive waste is even more critical, as it melts through containers, and is radioactive for many centuries.
    One plan was to bury nuclear waste in the Yucca Salt mines in Nevada, below the water table, and away from earthquake activity. It did not go through, after many years and millions of dollars spent...

    CERCLA:
    Comprehensive=all
    Environmental=environment
    Response=responds to accidents
    Compensation=pays victims
    Liability=finds those resposible
    Act=something congress decides

    Also known as "superfund" is funded through a tax on hazmat (hazardous materials) industrial producers ("the polluter pays" principle)
    "Brownfields" are areas toxic for public use. We had one behind the elab ("Mount Edgar") which we cleaned up to build the elab, gaining LEED credits for cleaning up something we created ourselves...
    Two critical cases:
    Love canal, NY: Hooker chemical, toxic land, kids got sick, cancer, miscarriages, homeowners had to relocate:
    https://en.wikipedia.org/wiki/Love_Canal
    Times Beach, Missouri: Dioxin pollution, sprayed on the roads to reduce dust (dioxin is a contact carcinogen)
    https://en.wikipedia.org/wiki/Times_Beach,_Missouri
    Town was near a river, when it flooded, the dioxin went everywhere, entire town had to be abandoned.
