These are just some general thoughts that I’ve had on class
so far.

Some Pitfalls in Waste Export
During this first week
of class, I stopped to think on the video and our field trips and tried to tie
things together. It still surprises me how even nowadays we are still unaware
of the lack of long term sustainable plans for the future and the lack of common
environmental procedural consensus across countries. We might have a good sense
of how things work within our borders but once we step into foreign territory
we cannot really tell what really happens to the handling of waste and if any
regulations are being implemented. Somehow, the way our system works is not
sustainable, not only in the broad sense of not recycling enough within the
country but also in the sense that developed countries export waste to developing
countries, from which we also extract in huge part natural resources, and in
which feeble governments allow this to happen. The problem raised is that by
exporting cheap waste to other poorer countries with more space available and
less safe workplace investment that are willing to take it, not only
jeopardizes the emerging country’s standard of living conditions assuming that
handling and safety are somewhat lower and sneaky in those countries, but also
in the long run, the lack of supervision from abroad into those developing
countries will result into an aggravation of the global environment, and that
affects the developed countries too. It is also raised an ethical question here
too. That is just a short-term plan but not a long-term. We think we recycle
but do we really know what is the real destination of every material? Some of
the materials like paper or plastic might be kept within the country, however
where does electronic waste go? A follow up on the true externalized costs
concept mentioned in class would be the technological equipment waste or
e-waste. These links are some examples that really opened my mind into a new
perspective and made me think more skeptically about our waste disposal final
destination.

The True Cost of Cell Phones
One of the most fascinating topics presented in our class so far has been the idea of externalized cost. Externalized cost refers to the social cost, or an additional cost of a product that effects a third party. The externalized cost for cell phones are the violation of human labor rights in central Africa. Many of the materials used in the construction of cell phones are called conflict minerals because they are mined in under conditions of labor abuse and armed conflict across this region. The four main conflict minerals are: Coltan, Cassiterite, Wolframite, and Gold. These minerals are mined to produce tungsten, tantalum, and tin, which are integral to other technologies such as laptops and mp3 players.
The three main countries that extract conflict minerals are from the Republic of Congo, Rwanda, and Uganda. Many of the workers in these mines are children, and sometimes work up to 48 hour shifts. These mines have no safety regulations and are susceptible to mudslides and collapse, also the majority of the mines are under constant surveillance by armed guards.The profits obtained from the extraction and sell of these minerals are used to fund the military groups which replenishes their resources for armed combat instead of funding infrastructure, health care, or education.
The next you pick up your phone, think about the true cost that went into the creation of that device. Think of the countless labors endured by the miner who extracted the material to create a device that provides convenient communication for western society.

Waste to Energy
After
our field trip to Covanta, I was interested in learning more about
waste to energy plants. I was especially curious about how well they
could control emissions. I found a website that explained how WTE
facilities have to follow very strict policies under the Clean Air
Act or face closing. I was surprised to find that many even surpass
the regulations and have cleaner emissions than required.
Issues on Rare Earth Minerals
With the development of technology, rare earth mineral, which contains one or more rare earth elements as major metal constituents, plays an important role in the industry around the world, from cellphone manufacture to missile construction. Unlike other minerals, such as copper, which spread around most places, rare earth minerals only distribute in several areas, such as Africa and south Asia. Besides, 43% of the world rare earth mineral storage is in China.
However, rare earth mineral has been facing a lot of issues and is almost at an urgent point of running out.
Hold china as an example, when the world rare earth mineral market first opened, the price of rare earth mineral did not show its real value. Comparing to the price of gold and copper which has tripled, the price of rare earth mineral has only increased 150%. People who live on rare earth mineral exploitation have to extract and sell a huge amount of those mineral to expand interests and gain profits. When the world market continues to develop and people begin to realize the real value of rare earth mineral, the price of rare earth mineral skyrockets. More people see the money underneath their ground and more people start to crazily extract those mineral. Jiangxi, a province in southern China, holds 36% of China's rare earth mineral storage and has encountered severe environmental problems of desertification, soil loss and water pollution. Besides environmental destruction, with the increase of rare earth mineral demand, people who only see the immediate interests smuggle the minerals and cause a huge amount of mineral waste while mining and transporting. Therefore, the storage of rare earth mineral is decreasing sharply.
To eliminate the issues above, rare earth mineral exporting countries begin to put restriction on rare earth mineral exploitation. This directly leads to problems to countries, such as japan, which purely rely on importing minerals to develop technology. With the restriction and decreasing amount, rare earth minerals are more and more difficult to get, but the world cannot stop developing for the shortage of rare earth minerals.
The only ways to solve this problem is to invent substitutes and recycling. Rare earth recovery can be done from extraction from e-waste such as hard-disk drive and Air Condition Compressor. Household trash can also be a source of rare earth recovery that rare earth can be extracted in glass waste.
There is no time to delay our actions. As our class promotes, be an active recycler to help the world!

What to do with Styrofoam
Today in class we separated our waste materials
into their proper categories for disposal: recycling, composting or discarding
to a landfill. As we were going through the items we ran into a problem with
the material Styrofoam, we were unsure about where to place the particular material
because it does not fit into the recycling categories: paper, plastic, metal,
or glass. So that leaves us with the question of what exactly is Styrofoam, and
where does it belong: the recycling bin, the compost box or the trash?
