Lana Chechack worked at the Landfill recycled garden to fulfill her Service Learning hours this term. Check this out:
I
worked with the Solid Waste Management, Perdido landfill. They aim to
provide society with exceptional waste collection, recycling and
disposal services that protect, preserve and improve our environment and
the quality of life in our communities. I worked with the recycled
garden at the landfill to find alternate uses for items that were
supposed to be dumped, but were comprehended by staff before they could
be disposed of. It use to be a drainage ditch, but with reconstruction
of paths with old bricks, tractor tracks, and blocks, we were able to
control how the water flowed to the drain. I maintained the tires that
were overrun by weeds, so the pre-existing plants were more appealing
and future plants could be added. Being in a landfill there was always
trash and maintenance to maintain on the area.
Even
though we have these landfills, the process of decomposition can’t keep
up with the growing human population. In Chapter 6 we see how
uncontrollably fast the world is repopulating. We see the IPAT model, a
formula that represents our total impact (I) on the environment results
from the interaction among the population (P), affluence (A), and
technology (T).Pollution has a direct correlation with people. Seeing as
we are the one with the technology to build, the more we create, the
more we throw our trash around. Depleting our resources and animals.
Since I was working with a drainage ditch, spraying reused pesticides
on ants, and seeing how the water flowed through it made me think of all
of the contaminates that our water has to go through. Chapter 12 states that groundwater
pollution is a serious problem. Surface water may be slightly easier to
deal with, but once it seeps underground the treatment process becomes
much more difficult. It shows how we are trying to treat the wastewater.
We had an in class activity on this, and concluded that even though we
can treat it, certain standards allows unwanted substances in our
“clean” drinking water. With huge landfills what kind of harm is it
backlashing against our water?
While volunteering at the landfill I was able to observe the processes
they go through with the waste. I knew from prior knowledge that the
stacked up trash emitted different gasses, but in Chapter 16 I learned
they harness biopower for generating electricity, and use the “landfill
gas” to burn at power plants. We can substitute biomass for up to 15% of
the coal with only minor equipment modification and no appreciable loss
of efficiency. With other biomass options it helps, but the book states
it wouldn’t be a sufficient energy source to provide for the whole
globe.
Waste generation is in no doubt rising. The U.S has been coined “the
throwaway state,” because of the nondurable goods packaged to be
disposed. The U.S. Environmental Protection Agency states, “U.S.
citizens produced 251 million tons of solid waste, almost 1 ton per
person. The average American generating 4.6 lb of trash per day.”
Chapter 17 dumbs down the regulated sanitary landfills, where waste is
buried or piled in large to decompose. Bacteria controls the major
process. The bottoms and sides of sanitary landfills must be lined with
heavy duty plastic and 2-4 ft of impermeable clay to help prevent
contaminants from seeping into aquifers. They also have systems designed
to collect and treat leachate, the liquid from dissolving substances
mixing with rain water.
After putting my time into the Perdido landfill and observing
everything going on around my surrounding I learned more hands on about
the world than just reading it through my book. It caused me to ask more
questions and understand it more. I still am left wondering why the
blackbirds and white birds don’t alternate seasons, instead they
coexist.
